Myosin - Gym Workout Tracker

Myosin

About this app

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 — all offline-first.

WORKOUTS YOUR WAY
Build workout routines with any structure — straight sets, supersets, drop sets, circuits, or custom blocks. Schedule your training by day, start your workout 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 training 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 habit templates or create your own.

PROGRESS YOU CAN SEE
See your training volume, frequency, and trends over time. Spot what's working and what isn't. Your workout data tells the story your body can't put into words.

OFFLINE-FIRST BY DESIGN
Train in the gym without signal. Lose connection mid-workout. Switch devices on the road. This workout tracker works fully offline and syncs automatically when you're back online — your data is always safe.

DESIGNED, NOT BLOATED
Myosin is built around one belief: a workout tracker should disappear into the background and let you train. No ads, no popups, no upsells. Just the tools you need, ready when you need them.

PRIVACY AND DATA
