I couldn't find an open-source calisthenics tracking app, so I built one for my own training records. It's now polished enough to share.
Key points: - Full customization: No preset exercises, no locked features. Every exercise you create has access to all settings (reps/time, unilateral/bilateral, goals, per-exercise timers) - Two modes: Quick manual logging or guided workout with timers - Completely offline: No account, no tracking, no ads. Your data stays on your device.
