About this app

Muscle Memory is a workout log app built to make logging at the gym as fast and simple as possible.

✅ Start as a guest
No sign-up needed — open the app and start logging right away.

✅ Input built for each exercise
Weight exercises take weight and reps, bodyweight exercises take reps only, timed exercises like planks take time, and cardio takes distance and time. Weight carries over from your last set or last session, so you rarely type it twice.

✅ Works offline
No connection? Your workout still saves to your device first, then syncs automatically once you're back online.

✅ Find and organize exercises
Search exercises by body part, and drag sets to reorder them.

✅ A clear summary when you finish
See total volume, workout time, and every exercise you logged. Past workouts are always there to look back on.

✅ Your preferred units
Switch weight (kg/lb) and distance (km/mi) units anytime in settings.

✅ Korean, English and Japanese
Change the app language right from settings.
