Metrya is a new iOS app that does something Apple hasn't built into Health itself: it lets you talk to your data.
The app connects your Apple Health records - sleep, heart rate, activity, blood oxygen, and everything else collected across your Apple devices - to an AI model of your choice. You bring your own API key for Claude, GPT-4, or Gemini. Your health data flows directly between your device and the AI provider; Metrya doesn't store it on its own servers.
The practical use case is natural language queries over your health history. Instead of manually cross-referencing charts in the Health app, you ask questions: why does my sleep score dip on certain days, what does my resting heart rate trend look like over six months, how does my activity compare to last quarter. The AI reads your data and responds in plain English.
For users serious about self-tracking who don't want to export CSVs or pay for a coaching subscription, the architecture here - free app, pay-per-query AI costs, no data middleman - is sensible. Whether Metrya builds enough of an audience to sustain the product long-term is the real question for an indie iOS app in this space.
Available now on iOS.
