Myosin - Gym Workout Tracker

Myosin logs your training set by set: gym routines, lifting, calisthenics, sports and habits, in one app that works offline and has no ads.

BUILD YOUR ROUTINE
Four block types: single, superset, circuit and HIIT. Circuits run by rounds, AMRAP, For Time or EMOM, and HIIT comes with Tabata ready to go. Ten set types, like warm-up, drop set, rest-pause, cluster or to failure, with RPE, tempo and notes. Assign days to each routine and Myosin shows you today's. Just starting out? Pick a template and train in minutes.

LOG WITHOUT LETTING GO OF THE BAR
One set, one tap. Rest timer with alarm, rounds and interval clock, plate calculator and generated warm-up sets. On iPhone, your workout stays on the Dynamic Island and the lock screen.

RECORDS THAT ARE REAL
Myosin detects ten kinds of personal record: heaviest weight, estimated 1RM, best reps, duration, distance, pace and more. They light up only when you've truly beaten your mark.

CALISTHENICS, STEP BY STEP
21 progression paths and 257 steps: pull-ups, handstand, muscle-up, front lever, planche, human flag, dragon flag. Every step has one goal to achieve it and another to master it.

YOUR PROGRESS, ON ONE SCREEN
By week, month or year: sets per muscle, your strength over the last three months, records, consistency and time trained. Every exercise also gets its own curve.

YOUR BODY
Log your weight and measurements. Myosin shows you the trend, not the noise of the scale.

HABITS, NO GUILT
Sleep, recovery, supplements, nutrition and mind. One tap a day, with reminders and widgets to check them off without opening the app.

SPORTS AND CLASSES
Soccer, padel, running, swimming, yoga, spinning, martial arts and more: over twenty activities count toward your week alongside the gym.

YOUR CIRCLE
Invite friends with a link, see their workouts, compare your lifts with theirs and copy their routines. You decide whether you share.

WORKS WITHOUT SIGNAL
Everything is saved on your phone first. Train in a basement with no connection: Myosin syncs on its own when the signal comes back, and you can switch phones without losing anything.

YOUR DATA IS YOURS
No ads and no ad tracking. Export everything as JSON or CSV and delete your account anytime. If you use Claude or ChatGPT, you can connect them to Myosin so they can read your training and build routines for you.
