FitNotes

A developer known as DuarteSantos8 has released openGym, a self-hosted gym and body-weight tracker built in JavaScript. The tool lets users plan routines, log workouts including supersets, warm-ups and cardio, and visualise which muscles are trained, fatigued or detraining. It supports imports from FitNotes, Strong and Hevy, and offers passkey login, with all data stored on the user's own server.
