General guidance from repository metadata, not legal advice. How we score
From the README
A self-hosted gym & body-weight tracker you actually own.
Plan your week, run guided workouts, track every set and your body weight over time — on your phone, synced across devices, behind your own passkey login. No account on someone else's server, no subscription, no ads. Just
docker compose up.Screenshots, docs and the APK download live on the site.
Want to poke at it first? The in-browser demo is the real app with example data — no account, nothing to install.
Most workout apps lock your data behind a login on their servers, nag you to upgrade, or disappear when the startup does. openGym is the opposite: it runs on your box, your data stays in a folder you control, and it's yours to fork. It still feels modern — installable as a home-screen app, passkey sign-in, offline support, sync across your phone and laptop.
