Ultrahuman is a consumer health-tech startup that provides daily well-being insights to users based on biometric data from the company’s wearables, like the RING Air and the M1 Live Continuous Glucose Monitor (CGM). The Ultrahuman team leaned on Gemini in Android Studio's contextually aware tools to streamline and accelerate their development process.

Ultrahuman’s app is maintained by a lean team of just eight developers. They prioritize building features that their users love, and have a backlog of bugs and needed performance improvements that take a lot of time. The team needed to scale up their output of feature improvements, and also needed to handle their performance improvements, without increasing headcount. One of their biggest opportunities was reducing the amount of time and effort for their backlog: every hour saved on maintenance could be reinvested into working on features for their users.

Solving technical hurdles and boosting performance with Gemini

The team integrated Gemini in Android Studio to see if the AI enhanced tools could improve their workflow by handling many Android tasks. First, the team turned to the Gemini chat inside Android Studio. The goal was to prototype a GATT Server implementation for their application’s Bluetooth Low Energy (BLE) connectivity. 

As Ultrahuman’s Android Development Lead, Arka, noted, “Gemini helped us reach a working prototype in under an hour—something that would have otherwise taken us several hours.” The BLE implementation provided by Gemini worked perfectly for syncing large amounts of health sensor data while the app ran in the background, improving the data syncing process and saving battery life on both the user's Android phone and Ultrahuman's paired wearable device.

Beyond this core challenge, Gemini also proved invaluable for finding algorithmic optimizations in a custom open-source library, pointing to helpful documentation, assisting with code commenting, and analyzing crash logs. The Ultrahuman team also used code completion to help them breeze through writing otherwise repetitive code, Jetpack Compose Preview Generation to enable rapid iteration during UI design, and Agent Mode for managing complex, project-wide changes, such as rendering a new stacked bar graph that mapped to backend data models and UI models.

Transforming productivity and accelerating feature delivery 

These improvements have saved the team dozens of hours each week. This reclaimed time is being used to deliver new features to Ultrahuman’s beta users 10-15% faster. For example, the team built a new in-app AI assistant for users, powered by Gemini 2.5 Flash. The UI design, architecture, and parts of the user experience for this new feature were initially suggested by Gemini in Android Studio—showcasing a full-circle AI-assisted development process.
