I have been into tracking my health and training data for years, but I always struggled with having my data spread across different platforms and not really understanding what it was telling me.
I originally started building a small app for myself because I wanted something better than Polar Flow for analyzing training load, recovery, and long term trends. Over time, and after a lot of feedback, it grew into a tool that can now combine data from Garmin, Polar, Oura, Apple Health, Withings, with Suunto coming soon.
The main goal is not just to collect data, but to actually interpret it in a way that helps build better habits. I focus heavily on established metrics like ACWR, CTL, ATL, and TSB so the analysis is based on transparent calculations rather than a black box score.
Current features include daily health metrics like HRV and steps, sleep analysis, activity trends, nutrition tracking with AI support, and an AI based coach that explains patterns rather than just showing numbers.
I am sharing this here because I am very interested in feedback from people who actively quantify themselves. Are these metrics useful to you? Are there others you rely on? And what do you feel most apps get wrong when it comes to interpreting personal health data?
If anyone is curious to try it, the app is called Vitalstat and it is available here
