Myosin - Gym Workout Tracker

About this app

Myosin is a workout tracker built for people who take training seriously. Design your own routines, track every set and rep, hit personal records, and build the habits that move the needle — all offline-first. WORKOUTS YOUR WAY Build routines with any structure — straight sets, supersets, drop sets, circuits, or custom blocks. Schedule by day, start training with one tap, and never lose your place again. TRACK EVERY REP Log sets in real time with built-in rest timers. Myosin automatically detects personal records, so you always know when you're getting stronger. No guesswork, no spreadsheets. BUILD HABITS THAT STICK Complement your training 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, frequency, and trends over time. Spot what's working and what isn't. Your 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. Everything works 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 in your face. Just the tools you need, ready when you need them. KEY FEATURES - Custom routine builder with supersets, circuits, and rest blocks - Real-time workout tracking with built-in rest timers - Automatic personal record detection (1RM, volume, reps) - Open habit tracker — sleep, recovery, hydration, anything you want - Weekly progress insights and training analytics - Home screen widgets for streaks and quick stats - Full offline support with automatic cloud sync - Dark mode interface designed for gym lighting - Account deletion and data export available anytime - No ads, no third-party trackers WHO IT'S FOR Myosin is for lifters, strength athletes, hybrid trainers, and anyone serious about getting stronger and tracking what actually works. If you've outgrown spreadsheets and want a tool that respects your time and your training, this is for you. PRIVACY AND DATA Your training data belongs to you. Myosin stores everything locally on your device first and syncs to the cloud only to back up your data and let you switch devices. We don't sell your data, we don't show you ads, and you can delete your account anytime. GET STARTED Create your first routine in under two minutes. Log your first workout. Watch the personal records start adding up. That's all you need to do.

IN-APP GUIDES 21 walkthroughs that show you where everything lives: building a superset or a circuit, generating warm-up sets, using the timer, sharing a routine, and more. You'll find them in Profile, and each one takes you straight to the screen it explains. FORGOT TO END YOUR WORKOUT It happens. Now, when a session is left open, Myosin works out how long you actually trained and offers you that duration before saving, instead of counting the hours the app stayed open. STARTING A WORKOUT IS MORE DIRECT The tab is now called Train, and it lets you start in one tap without having to build a routine first.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
