Muscles

Muscles is a private workout tracker for people who simply want to train well — without accounts, cloud storage, ads, or distractions.

Build your own workout plans, choose exercises from the built-in library, log sets, weights and reps, and track your progress.

Browse exercises by muscle group and equipment, check instructions, and keep your training history in one place.

No account. No cloud. No ads. Your workout data stays on your device.

-=| Your plan. Your workout. |=-

We do not force you into ready-made programs or a single way of training.

Build your workouts, add exercises, set your sets, weights, reps and rest times. Reorder exercises, add or remove sets, and make changes even during a workout.

Muscles adapts to the way you train — not the other way around.

-=| Built-in exercise library |=-

Find the exercise you need without leaving the app.

Browse the exercise library by muscle group and equipment. Add exercises directly to your workout plans.

Exercise pages include descriptions, step-by-step instructions and illustrations showing how each movement is performed.

Can't find what you need? Create your own custom exercises.

-=| Stop guessing what you did last time |=-

“How much did I lift last time?”
“How many reps did I do?”
“Was it 80 or 85 kg?”

Muscles keeps your workout history, including exercises, sets, weights and reps.

Quickly look back at previous sessions and see exactly what you did.

-=| Rest without watching the clock |=-

The built-in rest timer tracks your breaks between sets.

Shorten or extend your rest, set a custom duration, or end it early. Notifications still work when your phone is locked.

You recover. Muscles keeps the time.

-=| See your progress |=-

Muscles PRO helps you see how your training changes over time.

Progress charts, records, PRs and Previous Performance make it easy to compare your results and see what you achieved last time.

Live workout ETA shows roughly how much time you have left, while estimated plan duration helps you plan your day.

-=| Training with someone? Share your plan |=-

Training with a friend, partner or coach?

Share your plan with a QR code or file. They can load it directly without retyping exercises or rebuilding the workout.

Just show the code and train from the same plan.

-=| Your data is yours |=-

Muscles works locally and offline.

No account.
No cloud.
No ads.

Your workout data stays on your device. Create backups and move your data whenever you choose.

-=| OpenDyslexic — a more readable interface |=-

Muscles PRO includes OpenDyslexic, an optional typeface that some readers find easier to distinguish and follow.

It may be preferred by people with dyslexia, ADHD, or anyone who finds its distinctive letter shapes easier to read and focus on.

Enable it with a single setting.

-=| Try everything first |=-

Your first 15 qualifying workouts give you full trial access to every feature.

Use Muscles during real training sessions and decide whether PRO is right for you.

After the trial, core workout features remain free. Your data and history stay intact, and you can continue logging workouts.

You do the training.
