Myosin - Gym Workout Tracker

Myosin is a workout tracker built for people who take training seriously. Design your own gym routines, track every set and rep, hit personal records, and build the habits that move the needle, and it all works offline. WORKOUTS YOUR WAY Build routines with any structure — straight sets, supersets, drop sets, circuits, or custom blocks. Schedule them by day, start with one tap, and never lose your place again. TRACK EVERY REP Log your sets in real time with built-in rest timers. Myosin automatically detects personal records, so you always know when your strength work is paying off. No guesswork, no spreadsheets. BUILD HABITS THAT STICK Complement your workouts with a flexible habit tracker. Sleep, hydration, recovery, supplements, mindset — track whatever matters to your progress. Pick from curated templates or create your own. PROGRESS YOU CAN SEE See your volume per muscle, your frequency, and your trends over time. Spot what's working and what isn't. Your data tells the story your body can't put into words. WORKS WITHOUT SIGNAL Train in the gym without signal. Lose connection mid-session. Switch devices on the road.
