A developer named Duarte Santos has released openGym, a self-hosted JavaScript app for planning routines and logging gym and body-weight workouts, including supersets, warm-ups and cardio. It maps which muscles are trained, fatigued or detraining, and can import data from FitNotes, Strong and Hevy, with passkey login. The pitch is full data ownership: everything runs on the user's own server, appealing to fitness app users wary of subscriptions and cloud lock-in.
