Aarogya Setu 2.0 launches with Google's Gemma 4 and open Medical Data Toolkit

India's National Health Authority launched the new Aarogya Setu 2.0 app on Monday, rebuilding the COVID-era contact-tracing tool into a unified platform for personal health records and government health services.

The app runs on Google's Gemma 4 open models and its Medical Data Toolkit, which together turn messy medical paperwork into something patients and doctors can actually use.The problem they're solving is a familiar one. Health records arrive as a jumble of lab reports, scans, and printouts, often unstructured and hard to read. Gemma 4 and the toolkit work in tandem to identify what kind of record they're looking at, then pull out the details that matter, like test names, methods, and results, from both text and images.The toolkit then maps that information into FHIR data, the standard format that lets different healthcare systems share records without friction. The practical payoff: when a patient moves between hospitals or providers, their history travels with them instead of getting lost in translation. Inside the app, users stay in control of all their health records.Google has also open-sourced the Medical Data Toolkit, handing it to developers and health organisations at no cost.

The first release is tuned for the most common record types, such as lab reports and observations, and helps apps comply with interoperability standards under the Ayushman Bharat Digital Mission. Gemma 4 itself launched back in April 2026.Preeti Lobana, Vice President and Country Manager at Google India, said the tools are meant to give Indians tighter control over their health journeys while lowering the barrier for health-tech startups. The toolkit builds on an earlier Google release, a wrapper that helped Indian developers plug their apps into the ABDM architecture.
