openGym

openGym is a self-hosted gym and body-weight tracker: routines over a library of 1,300+ exercises with animated demos, guided workouts with rest timers and PR detection, progression rules (linear, Greyskull, double progression), strength balance ratios, body-weight charts and progress photos. Passkey (Face ID / Touch ID / fingerprint) login, offline-capable PWA installable on the home screen, data stored as plain files in a folder you own and back up.

This package runs openGym natively: the API as a systemd service under its own user, the frontend as static files served by nginx — no Docker. Passkeys work over the app's own accounts; YunoHost SSO deliberately does not provide the identity (openGym has no LDAP mode), so access control on the portal side is "who may reach the page", and accounts are created inside openGym.
