Level up your apps with the latest features from Android Health

Posted by Breana Tate - Developer Relations Engineer, Android Health

Android Health’s mission is to enable billions of Android users to be healthier through access, storage, and control of their health, fitness, and safety data. To further this mission, we offer two primary APIs for developers, Health Connect and Health Services on Wear OS, which are both used by a growing number of apps on Android and Wear OS.

AI capabilities unlock amazing and unique use cases, but to be ready to deliver the most value to your users at the right time, you need a strong foundation of data. Our updates this year focus on helping you build up this data foundation, with support for more data types, new ways to access data, and additional methods of getting timely data updates when you need them.

Changes to the Google Fit APIs

We recently shared that Google Fit developer services will be transitioning to become a core part of the Android Health platform. As part of this, the Google Fit APIs, including the REST API, will remain available until June 30, 2025.

Health Connect is the recommended solution for storing and sharing health and fitness data on Android phones. Beginning with Android 14, it’s available by default in Settings. On pre-Android 14 devices, it’s available for download from the Play Store. Health Connect lets your app connect with hundreds of apps using a single API integration. To date, over 500 apps have integrated with Health Connect and have unlocked deeper insights for their users. Check out the featured list to see some of the apps that have integrated.

We’re excited to continue supporting the Google Fit Android Recording API functionality through the Recording API on mobile, which allows developers to record steps, and soon distance and calories, in a power-efficient manner. In contrast to the Google Fit Android Recording API, the Recording API on mobile does not store data in the cloud by default, and does not require Google Sign-In. The API is designed to make migrating from the Fit Recording API effortless. Keep an eye on d.android.com/health-and-fitness for upcoming documentation.

Upcoming capabilities from Health Connect

Health Connect will soon add support for background reads and history reads.

Background reads will enable developers to read data from Health Connect while their app is in the background, meaning that you can keep data up-to-date without relying on the user to open your app. This is a departure from current behavior, where apps can only read from Health Connect while the app is in the foreground or running a foreground service.

History reads will give users the option to grant apps access to all historical data in Health Connect, not just the past 30 days.

With both background reads and history reads, users are in control. Both capabilities require developers to declare the respective permissions, and users must approve the permission requests before developers can make use of the data protected by those permissions. Even after granting approval, users have the option of revoking access at any time from within Health Connect settings.

Both features will be released later this year, so stay tuned to learn how to add support to your apps!

Updates to Health Services on Wear OS

Health Services on Wear OS is a set of APIs that makes it simple to create power-efficient health and fitness experiences on Wear OS.

In Wear OS 5, we’re introducing 2 new features:

    • New data types for running
    • Support for debounced goals

New Data Types for Running

Starting with Wear OS 5, Health Services will support new data types for running. These data types can help provide additional insights on running form and economy.

The full list of new advanced running metrics is:

    • Ground Contact Time
    • Stride Length
    • Vertical Oscillation
    • Vertical Ratio

As with all data types supported by Health Services on Wear OS, be sure to check exercise capabilities so that your app only uses metrics that are supported on the devices running your app, creating a smoother experience for users. This is especially important for Wear OS, as there is a strong ecosystem of devices for consumers to choose from, and they don’t always support the same metrics.

// Checking if the device supports the RUNNING exercise and confirming the 
// data types that are supported.
suspend fun getExerciseCapabilities(): ExerciseTypeCapabilities? {
   val capabilities = exerciseClient.getCapabilitiesAsync().await()
   return if (ExerciseType.RUNNING in capabilities.supportedExerciseTypes) {
   } else {

. . .

// Checking whether the data types that we want to use are supported by
// the RUNNING exercise on this device.
val dataTypes = setOf(
Checking exercise capabilities with Health Services on Wear OS

To make this easy, we’ve introduced a sensor panel, available starting in Android Studio Koala Feature Drop, which is currently in Canary. You can use the panel to test your app across a variety of device capabilities, experimenting with situations where metrics like heart rate or distance aren’t available.

Support for debounced goals

Second, Health Services on Wear OS will soon support debounced goals for instantaneous metrics. These include metrics like heart rate, distance, and speed, for which users want to maintain a specified threshold or range throughout an exercise.

Debounced goals prevent the same event from being emitted multiple times—every time the condition is true—over a short time period. Instead, events are emitted only if the threshold has been continuously exceeded for a (configurable) number of seconds. You can also prevent events from being emitted immediately after goal registration.

This support comes from two new ways to better time goal alerts for instantaneous metrics: duration at threshold and initial delay:

    • Duration at threshold is the amount of uninterrupted time the user needs to cross the specified threshold before Health Services sends an alert event.
    • Initial delay is the amount of time that must pass, since goal registration, before your app is notified.

Together, these features reduce the number of false positives and repeated alerts surfaced to users if your app lets users set fitness goals or targets.

The differences between Duration at Threshold and Initial Delay

A common use case for debounced goals involves heart rate zones. Heart rate continuously fluctuates throughout an exercise, especially during cardio-intensive activities. Without support for debouncing, an app might get many alerts in a short period of time, such as each time the user’s heart rate dips above or below the target range.

By introducing an initial delay, you can inform Health Services to send a goal alert only after a specified time period has passed–think of this like an adjustment period. And by introducing a duration at threshold, you can take this customization further, by specifying the amount of time that must pass in (or out) of the specified threshold for the goal to be activated. In practice, this would be like waiting for the user to be out of their target heart rate range for 15 seconds before your app lets them know to increase or decrease their intensity.

Evolving Health on Android: Migrating from Google Fit APIs to Android Health

Posted by Chris Wilk – Senior Product Manager, Android Health

At Google, we're committed to empowering developers to create innovative health and fitness experiences on Android. Over the past few years, we've been investing heavily in establishing the Android Health platform, making significant improvements to build a more unified, secure, and user-friendly health ecosystem. Our goal is to provide developers with a powerful, integrated health platform that reduces fragmentation and streamlines the development process.

What is changing

As a result of these advancements, we're excited to announce that Google Fit developer services will be transitioning to become a core part of the Android Health platform. This change allows us to better serve developers and users, providing a seamless experience across the platform.

As part of this transition, Google Fit APIs, including the REST API, will remain available until June 30, 2025, giving developers ample time to migrate to Android Health. Starting today, new sign-ups for the Google Fit APIs will no longer be accepted as we focus on enhancing the Android Health platform.

What this means for developers

Developers Using Google Fit APIs for Android

If you are a developer using Google Fit APIs for Android, we recommend migrating to Android Health products now to ensure uninterrupted service for your users. Android Health APIs offer several advantages over the Google Fit APIs for Android, including:

    1. Recording steps, distance, and calories: In the near future, Android Health will provide the Recording API on mobile, which doesn’t require a Google user account or the need for you to request access to API scopes. And it is more battery-efficient than using Android SensorManager (ASM). The Recording API will launch with steps, and soon support distance and calories.

    2. Accessing recorded data: The Recording API on mobile will enable developers to access up to 10 days of recorded data.

    3. Storing and sharing data between apps: By integrating with Health Connect, your Android app can access data from a growing ecosystem of apps with just one connection. Plus, data is stored on-device, ensuring the user is in full control of their data.

To help you get started with the migration process, we've created a comprehensive migration guide. This guide will walk you through the steps needed to transition your app from Google Fit APIs to Android Health products, primarily Health Connect, to ensure a smooth experience for both you and your users.

Developers using Google Fit REST APIs

Our Android Health API offerings have moved to an on-device model, so there will not be an alternative to the Fit REST API. Where possible, we encourage Fit REST API users to migrate to Android Health APIs.

In addition to Fitbit which supports Health Connect today, partners like Withings, Signos, Oura, Peloton, and Lifesum are already building innovative experiences with Android Health products. As more developers embrace this powerful set of APIs, we anticipate a thriving ecosystem of connected health and fitness apps that empower users to take control of their wellbeing.

We're committed to supporting you throughout this transition and can't wait to see the innovative solutions you'll create. If you encounter issues, have proposals for features you would like to see, or have any feedback, please provide them here.

We will share more details about what’s next for Android Health at Google I/O on May 14, 2024. Stay tuned for updates and announcements during the event.

Health Connect brings together Peloton, ŌURA, and Lifesum for deeper health and fitness insights

Posted by the Android team

Health Connect is an Android API that gives users a simpler way to consolidate and share their health and fitness data across applications. With Health Connect, users can opt to share their health and fitness metrics between their favorite apps. And for developers, Health Connect helps streamline workflows and reduce API complexities.

By using Health Connect, Peloton, ŌURA, and Lifesum were able to provide their users more information about their health by bridging the gap between the specific types of health metrics available on each application. Together, these metrics can provide a clearer, more holistic view of users’ health. And thanks to Health Connect’s intuitive APIs, implementing these changes has become easier than ever. Rather than having to build multiple API integrations to support access to multiple datasets, Health Connect saved engineers time by only requiring one.

Peloton provides more metrics with a single API integration

The Peloton team received numerous requests from its Members asking for integrations with other platforms. Because of this, Peloton engineers saw an opportunity to give them a more holistic view of their wellness information by supporting easier access to the data they track across each of their health and fitness apps. But the Peloton team was concerned by the time and cost that developing individual API connections for each app would require.

“We would have to coordinate road maps, marketing, and support, and it isn’t feasible to do these things for every service we’d like to work with,” said Eder Bastos, a senior Android engineer at Peloton. “By integrating Health Connect, we don’t need to do any additional implementation work to support other services.”

Maintaining a single Health Connect API integration to share data with other health and fitness apps saves Peloton developers time and effort. When updates are made to the Health Connect API, the Peloton team can adopt those changes and receive all the benefits at once, rather than maintaining multiple APIs for each potential partner’s platform.

Roughly 20% of Peloton’s new Members now use Health Connect. Health Connect also increased Member engagement in the Peloton App, driving a 10% increase in Members using Peloton to log their workouts over time when the Health Connect API was enabled.

“Having a standardized API we can target allows us to share our data to an ecosystem, rather than targeting individual apps and services.” — Eder Bastos, senior Android engineer at Peloton

Health Connect helps ŌURA securely synergize data for its users

Health Connect provided the ŌURA team a seamless way to synergize user information across health and fitness applications. By giving their members access to the data they track where they need it, they’re able to monitor their health in the ways that work best for them—including syncing data from other health apps like Peloton.

For instance, when an ŌURA member takes a Peloton strength class, they can choose whether to share their data with the Health Connect API in their permission settings. If they opt to share the data, ŌURA can then read it from Peloton and show the member a full view of their fitness journey in the ŌURA application—and make personalized suggestions for their future workouts.

ŌURA not only reads exercise data but can also write sleep data from the ŌURA Ring. When connected to its signature wearable, the ŌURA app can track sleep stages, duration, heart rate, and heart rate variability. With a member’s permission, ŌURA can then share this data with other apps integrated into their member’s Health Connect ecosystem.

“Integrating Health Connect was a smooth experience, thanks to its good documentation," said Alex Earll, a senior backend engineer at ŌURA. “Some developers might not have the resources to directly integrate with ŌURA’s API, so we offered Health Connect as a turnkey solution to fit their product.”

Thanks to Health Connect, the ŌURA team nearly doubled the number of Android users importing workouts. The number of weekly workouts imported from Android has also increased by 95% since ŌURA integrated Health Connect last November.

ŌURA engineers are actively planning to use the Health Connect API to read and write additional data so people get an even more comprehensive image of their health. That includes movement data like active calories burned, step counts, and workout duration.

Lifesum integrates Sleep X Nutrition feature with Health Connect

Holistic wellness is dependent on more than a person's diet, which is why the nutrition app Lifesum enabled its users to import their sleep data via Health Connect. With this integration, users can sync external sleep data with the Lifesum app. This helps them better understand the correlation between how they eat and sleep and provides a more holistic view of their health.

With Health Connect, Lifesum users can easily import their sleep data from ŌURA and other data, like exercise and steps, from other apps within the Health Connect ecosystem. Then, Lifesum’s new feature, Sleep X Nutrition, can provide insights into how dietary choices impact sleep and vice versa.

Combining the power of two fields—ŌURA, an expert in sleep, and Lifesum, an expert in nutrition—allowed both platforms to create a richer, more insightful user experience around health.

“Mediating a relationship with ŌURA through Health Connect lets Lifesum users track more information about their sleep, such as duration and quality," said Kajsa Ernestam, a product manager at Lifesum. “It also helps Lifesum provide personalized sleep insights and actionable feedback to improve users’ eating habits and reach their goals.”

By integrating Health Connect with its new Sleep X Nutrition feature, Lifesum cut its development time by an estimated 75%. Additionally, Lifesum increased organic installations by 3X during the promotional period of the new Sleep X Nutrition feature in the Play Store.

“Lifesum cut its development time by an estimated 75% by integrating Health Connect with its new Sleep X Nutrition feature.” — Oskar Florén, lead Android developer at Lifesum.

More opportunities with Health Connect

Today, there are over 50 apps integrated with Health Connect, and that number continues to grow. As new apps join the Health Connect ecosystem, each app directly benefits from a greater variation of health data that they can read and write to.

Health Connect is coming to Android 14 this fall. This will make it even easier for users who opt in to control how their health and fitness data are shared across apps.

“We’re really excited to see more seamless integration of Health Connect into Android 14,” said Eder from Peloton. “Downloading a separate app can be too much overhead for some people, so we’re excited to see even more Health Connect usage as it becomes easier to access.”

What’s new in Android Health

Posted by Sara Hamilton, Developer Relations Engineer

Health and fitness data is interconnected – sleep, nutrition, workouts and more all inform one another. For example, consider that your sleep impacts your recovery, which impacts your readiness to run your favorite 5k. Over time, your recovery and workout habits drive metrics like heart rate variability, resting heart rate, VO2Max and more! Often this data exists in silos, making it hard for users to get a holistic view of their health data.

We want to make it simple for people to use their favorite apps and devices to track their health by bringing this data together. They should have full control of what data they share, and when they share it. And, we want to make sure developers can enable this with less complexity and fewer lines of code.

This is why we’ve continued to improve our Android Health offerings, and why today at I/O 2023, we’re announcing key updates across both Health Connect and Health Services for app developers and users.

What is Android Health?

Android Health brings together two important platforms for developers to deliver robust health and fitness app to users; Health Connect and Health Services.

Health Connect is an on-device data store that provides APIs for storing and sharing health and fitness data between Android apps. Before Health Connect, there was not a consistent way for developers to share data across Android apps. They had to integrate with many different APIs, each with a different set of data types and different permissions management frameworks.

Now, with Health Connect, there is less fragmentation. Health Connect provides a consistent set of 40+ data types and a single permissions management framework for users to control data permissions. This means that developers can share data with less effort, enabling people to access their health data in their favorite apps, and have more control over data permissions.

Health Services is our API surface for accessing sensor data on Wear OS devices in a power-efficient way. Before Health Services, developers had to work directly with low-level sensors, which required different configurations on different devices, and was not battery-efficient.

With Health Services, there is now a consistent API surface across all Wear OS 3+ devices, allowing developers to write code once and run it across all devices. And, the Health Services architecture means that developers get great power savings in the process, allowing people to track longer workouts.

Health Connect is coming to Android 14 with new features

Health Connect is currently available for download as an app on the Play Store. We are excited to announce that starting with the release of Android 14 later this year, Health Connect will be a core part of Android and available on all Android mobile devices. Users will be able to access Health Connect directly from Settings on their device, helping to control how their health data is shared across apps.

Several new features will be shipped with the Health Connect Android 14 release. We’re adding a new exercise routes feature to allow users to share maps of their workouts through Health Connect. We’ve also made improvements to make it easier for people to log their menstrual cycles. And, Health Connect updates will be delivered through Google Play System Updates, which will allow new features to be updated often.

Health Services now supports more uses cases with new API capabilities

We’ve released several exciting changes to Health Services this year to support more use cases. Our new Batching Modes feature allows developers to adjust the data delivery frequency of heart rate data to support home gym use cases. We’ve also added new API capabilities, like golf shot detection.

The new version of Wear OS arrives later this year. Wear OS 4 will be the most performant yet, delivering improved battery life for the next generation of Wear OS watches. We will be releasing additional Health Services updates with this change, including improved background body sensor permissions.

Our developer ecosystem is growing

There are over 50 apps already integrated with Health Connect and hundreds of apps with health services, including Peloton, Withings, Oura, and more. These apps are using Health Connect to incorporate new data, to give people an interconnected health experience, without building out many new API integrations. Learn more about how these health and fitness apps are creating new experiences for users in areas like sleep, exercise, nutrition, and more in our I/O technical session.

We also have over 100 apps integrated with Health Services. Apps using Health Services are seeing higher engagement from users with Wear apps, and are giving their users longer battery life in the process. For example, Strava found that users with their Wear app did 25% more activities than those without.

Get started with Health Connect

We hope many more developers will join us in bringing unique experiences within Android Health to your users this year.

If you’d like to create a more interconnected health experience for your users, we encourage you to integrate with Health Connect. And if you are a Wear developer, make sure you are using Health Services to get the best battery performance and future proofing for all upcoming Wear OS devices.

Withings reduces 50% of its data sync code by streamlining health and fitness API integrations with Health Connect

Posted by the Android team

French consumer electronics company Withings hosts one of the largest ecosystems of digital health and wellness products in the world. The company’s products include smart watches, smart scales, blood pressure monitors, and its own health-tracking application. Formerly known as Health Mate, the Withings application gives Withings users an easy way to track all of their health information—like activity, weight, ECG records, and sleep—obtained from Withings devices.

While Withings works to create a central hub for its users to access their health-related data, the number of devices and applications for monitoring health has grown substantially. And as health and fitness data spread across multiple platforms, it can be difficult for users to easily track and analyze this information.

To extend access to additional metrics and give Withings users a chance to use the application with their non-Withings apps and devices, Withings integrated Health Connect, Android’s latest API offering that gives users a simpler way to consolidate and share their health and fitness data across applications.

Health data is more powerful together

Before integrating Health Connect, Withings users had to manually activate which health and fitness apps could sync data to and from the Withings app. Now, thanks to Health Connect, its users can grant permissions to new health and fitness applications and automatically sync their data to the Withings app, letting them find their data in one easy-to-manage place.

“We integrated Health Connect in Withings app to grow our health sphere and offer a more complete experience to our users by supporting a wider range of data,” said Sophie Zecri, a mobile software engineer at Withings. “Health Connect helped us create a richer health-tracking interface and a more efficient overview for users.”

By uniting health data using the Health Connect API, Withings application offers its users a more holistic view of their health and makes it easier to develop a deeper understanding of key health insights with the data they gather.

For instance, Withings’ users can now combine their other workout- or calorie-tracking applications with the Withings app. By doing this, users can more easily track how changes in one area of their health may be affecting another. Additionally, the Withings app can provide greater guidance and more specialized programs to meet each user's unique needs, such as specific dietary recommendations and recipes or more specialized exercise programs.

Withings also wanted the data available through the Withings application to be accessible in its users' other health and fitness apps. Integrating with Health Connect made this possible. “We wanted to extend access to additional metrics, giving our users a chance to use Withings devices with their other applications,” said Sophie.

Ensuring that users felt in control of their data was also a top priority for the Withings team. They saw Health Connect as a powerful tool that’s equally secure for both Withings and its users. With Health Connect, users can easily manage permissions in one place, with granular controls to see which apps are accessing data at any given time. And for Withings, setting up permission checks was as easy as dropping in a simple piece of code provided by Health Connect.

Simplify connectivity between apps with Health Connect

The amount of work required to connect with other third-party health and fitness applications was Withings’ biggest roadblock to giving its users access to additional syncs. All the APIs for every other app, with all their unique code, made integrations complex and expensive for Withings to maintain.

“Connecting with other apps’ APIs was onerous. Any changes had to be repeated for every API, which meant expanding the codebase and increasing the risk of bugs that could impact Withings app’s quality,” said Sophie.

Health Connect lets Withings developers maintain less code while preserving stability and minimizing potential bugs. This translates to a reduced codebase and increased productivity for other projects. By integrating Health Connect with the Withings app, Withings reduced the amount of code related to data sync with third-party applications by 50%.

Headshot of Sophie Zecri, Mobile Software Engineer at Withings, with quote, 'Integrating Health Connect was really rewarding for us. We're thrilled we can enrich the user experience by generating true synergy, letting users  dive deeper into the details of their health aspects.'

Preparing for a future with Health Connect

The Withings team attributes much of its success to the available Android resources for developers looking to integrate Health Connect with their company’s app. Withings developers used the Health Connect UX developer guide to aid the integration, and they used the Health Connect toolbox for testing and to understand how Withings app behaves with other applications that have integrated Health Connect.

The Withings team is excited to support new data types as its product range grows and new biomarker measurements become available. Currently, the company plans to expand its use of Health Connect by adding more data types related to women’s health.

“I would recommend Health Connect to other engineers looking to unite data for its users,” said Sophie. “Health Connect is a powerful, interesting, and easy tool to use.”

Leading Health and Fitness Apps Roll Out Health Connect Integrations

Posted by Sara Hamilton, Developer RelationsEarlier this year, we introduced Health Connect as a way for app developers like you to have early access to a platform that securely shares health and fitness data across Android devices, with user consent. We collaborated with Samsung to build this platform which simplifies the connectivity between your apps while providing centralized privacy controls for users. We are now making the Health Connect (Beta) app available for download in Google Play to give users a central place to manage their privacy settings with granular controls to see which apps have access to data at any given time.

Today, 10+ health, fitness and wellness apps are rolling out integrations with the platform including early adopters of Health Connect like MyFitnessPal, Oura and Peloton.
Against a light blue background, an illustration of a person and their dog looking at a large screen with a 3x3 display of health app icons: Lifesum, Fitbit, MyFitnessPal, Dexcom, Samsung Health, Oura, Peloton, Flo,and WW.
Through the first wave of integrations, we have seen Health Connect provide many key benefits to developers.

Reduced fragmentation makes it easier to give users more holistic health insights

By enabling health and fitness apps to talk to each other, each app is able to provide a user with better, more holistic health insights.

In the past, developers had to establish multiple API connections to share data between different apps and each integration was costly to build and maintain. This limited developers’ data sharing capabilities and made it hard for users to unlock this data so that it could be utilized in different apps.

Now, with Health Connect, building an integration with a new app is as simple as reading in new data from Health Connect, rather than building a whole new integration.

For example, Android users will now be able to sync and get credit for their Peloton workouts in apps like Oura, MyFitnessPal, WeightWatchers and Lifesum. Now, through a single integration with Health Connect, Peloton Members will have the option to share their workout stats across the ecosystem of apps they use to support their overall wellness.

Standardized data schema ensures data consistency between apps

Health Connect provides a standardized data schema which supports 40+ data types across 6 categories. The schema is intuitive to use and covers a wide range of use cases, from exercises to sleep tracking to vital signs. It only requires just a few lines of code to read and write any of these data types in Health Connect. Health Connect even supports complex aggregations so that you can completely customize your queries to your app’s use case.

"With Health Connect APIs, our engineers were able to easily adapt their existing architecture in order to read and write user health data such as nutrition, hydration, exercise, and steps. With this integration, we're now able to consume data from any 3rd party application that also writes to Health Connect, expanding our users' choices while allowing them more flexibility to grant granular permissions about which data they want to share"
– Jason Peterson, Chief Technology Officer of MyFitnessPal

Centralize privacy controls for users, with less code

Previously, users had to navigate to multiple apps to manage data permissions. And, developers had to build out permissions management UIs themselves.

With Health Connect, users can easily manage permissions in a single place, with granular controls to see which apps are accessing data at any given time.

For developers, Health Connect provides the permissions management hub and granular permissions UIs out of the box, so you can set this up quickly.

Introducing Health Connect, a new API for Android app developers to securely access user health data

Posted by Chris Wilk, Product Manager

Android Jetpack with heart beat for health 

From helping you log your meals with MyFitnessPal to getting a holistic view of your health with Withings, apps and devices are a source for many kinds of useful health and fitness data. As Android developers, connecting and sharing this data between apps can help you provide more meaningful experiences and insights for your users. However, much of this information is spread across multiple experiences and different devices, making it difficult to bring together. Moreover, there are no centralized privacy controls for Android users.

Introducing Health Connect

This is why we’ve created Health Connect, a platform and API for Android app developers. With user permission, developers can use a single set of APIs to securely access and share health and fitness data across Android devices.

We're building this new unified platform in collaboration with Samsung to simplify connectivity between apps. We appreciate Samsung’s collaboration as we roll out Health Connect to foster richer app experiences while also providing centralized privacy controls for users.

We've been working with developers including MyFitnessPal, Leap Fitness and Withings as part of an early access program. In addition, Samsung Health, Google Fit and Fitbit are adopting Health Connect. Starting today, all developers can get access to Health Connect's common set of APIs for Android via Android Jetpack.

Health Connect fits in with Google’s wider efforts to help billions of people be healthier, using our platforms and technology to connect and bring more meaning to health information.

How does Health Connect work?

How Health Connect Works

How Health Connect Works

Health Connect supports many common health and fitness data types and categories, including: activity, sleep, nutrition, body measurements and vitals like heart rate and blood pressure.

With user permission, developers can securely read from and write data to Health Connect, using standardized schema and API behavior. Users will have full control over their privacy settings, with granular controls to see which apps are requesting access to data at any given time. The data in Health Connect is all on-device and encrypted. Users will have the ability to shut off access or delete data they don’t want on their device, and the option to prioritize one data source over another when using multiple apps.

Getting started

It’s easy to get started with Health Connect. Health Connect’s single set of APIs makes it simple to manage permissions and read and write data. Here’s an example of how you can request permissions and then write some data.

First, build a set of the permissions you plan to request read or write access to. In this example we are reading and writing steps and heart rate.

private val permissions =

// then, create a permissions request for this set of permissions

Then, launch the permissions request, which will bring the user to the Health Connect permissions UI to grant permissions.

Once the user grants permission, you are ready to read and write data. Here’s an example of how to write steps data over a period of time. Include the total number of steps, start and end time, and timezone information, and then insert the data into Health Connect.

private suspend fun writeSomeData(client: HealthConnectClient) {
    val records = mutableListOf<Record>()

        count = 888,
        startTime = START_TIME,
        endTime = END_TIME,
        startZoneOffset = null,
        endZoneOffset = null,
    // add additional records as needed
