Personal health tracking application with zero telemetry, embedded SQLite database, multi-platform desktop and mobile support, nutrition logging, blood pressure analysis, and private peer sync.

Hi everyone,

I built HealthCoach, an open-source, local-first health and wellness companion designed to track weight, blood pressure, calorie budgets, and daily nutrition journals across desktop and mobile devices.

Most commercial wellness apps rely on mandatory account registrations, cloud lock-in, aggressive telemetry, and recurring subscriptions. HealthCoach takes the opposite path:

  • Local-First & Private: All data resides locally on your hardware. There is zero telemetry, tracking, or remote advertising.
  • Native Desktop & Mobile Support: Full native desktop builds for Linux and Windows, alongside an Android mobile client.
  • Offline Local Sync: Synchronize to a local file share, or peer-to-peer over local Wi-Fi without intermediate third-party servers (with optional Google Drive backup if preferred).
  • Open Source: Licensed under GPL. Codebase, architecture notes, and builds are fully open:

Google Play Closed Testing:
I’m currently working through Google Play’s 14-day closed testing hurdle to make the Android build publicly available on the Play Store. If you run Linux/Windows and would like to test the Android companion app, I’d greatly appreciate your help:
