Description
Most workout apps are built around someone else’s account system, servers and subscription.
With openGym you can host the app yourself and keep your workout data on your own machine.
It lets you plan weekly routines, follow guided workouts, record sets and reps, track body weight, and see your progress over time. The self-hosted version runs in a browser and can sync your data between devices using passkey authentication.
There is also a standalone Android app. It can work without an account or server.
It keeps your workout data directly on your phone while providing features such as native reminders and a rest countdown.
Use Cases
- Plan routines, log every set, track progression, and keep your training history in one place.
- Record your weight and compare your progress against a target over time.
- Host openGym yourself instead of keeping your training history on a third-party service.
- Import existing data from FitNotes, Strong, or Hevy and continue from your existing history.
- Install the Android APK for a standalone workout tracker with reminders and a rest countdown.

A Workout Tracker You Actually Control
A workout tracker doesn’t necessarily need to be tied to somebody else’s cloud account.
openGym gives you the option to run the whole thing yourself, with your workouts, body weight, routines, and settings stored on your own device.
This app is interesting for people who want a proper workout tracker without giving up control over where their data lives.
