Quick answers about the Muscla app. Can’t find yours? Write to support@muscla.app.
Is Muscla available yet?
Not yet. Muscla is coming to the App Store. Join the waitlist on the home page and we will email you once, when it is ready.
Do I need an account?
No. Muscla works fully without an account, and your workouts stay on your iPhone. An account lets you back up your workouts, use them on all your devices and get your plan in your calendar. The Community and the connection to AI assistants need an account.
How does the plan adapt?
After each exercise you answer one question: how many more reps could you have done? Muscla uses that answer and your logged sets to choose the next step in small percentages. If you prefer, you can rate every set with RIR or RPE in your settings. Deload weeks are planned for you and do not count as a failure.
Can I build my own routines or bring my data from another app?
Yes. You can edit routines, add your own exercises and put a routine on any day of your week. You can import your history from FitNotes, Strong or Hevy, and import a backup file made by Muscla.
How do I log food?
Scan a barcode, take a photo or describe the meal in a few words, and AI fills in the numbers. You can also search more than 1 million foods in 12 languages, save recipes and track water. Values from a photo or a description are estimates, so check them before you save.
How are my calorie and protein targets set?
Muscla sets them from your goal and adapts them over time. You can add extra kcal for training days, and a weekly check shows whether the target still fits your progress, so you can adjust it. You can change your targets yourself at any time.
Who can see my workouts and my food?
Muscla is private by default. Only followers you accept see your workouts, and you decide what each person sees. Food and body weight stay private until you decide to share them.
What are the leaderboards, and who can see me on them?
Leaderboards among friends work from the start. Public city and country lists open after 90 training days. In those lists your name, picture, city, body weight and best values are visible, and public lists are opt-in, and you choose in Visibility (You → Settings → Visibility). Lifts can be verified by video.
Does Muscla work on Apple Watch?
Yes. The Watch shows your rest timer and your next set. On the iPhone, a Live Activity keeps your rest countdown on the Lock Screen, and widgets show today's workout and the calories you have left.
Does Muscla use Apple Health?
Only if you connect it. Finished workouts and your weigh-ins go to Apple Health, and weigh-ins from scales and other apps come in. Muscla can also read heart rate variability, resting pulse and sleep from Apple Health for a hint on the Today screen. You can disconnect at any time. What is already in Health stays there.
What does Pro include, and what does it cost?
Muscla is free to start. Pro is an optional subscription that you buy and manage through your Apple account, and you can cancel any time there. It includes the connection to AI assistants. Prices and the free trial are shown in the app when Pro is available in your country.
How do I connect Claude or ChatGPT?
In the app, open You → Settings → AI assistants, copy the connector address and add it in your assistant. The steps for each assistant are on the Assistants page.
How do I back up my data or delete my account?
Under You → Settings you can export a backup of your workouts as a file and import it again. You can also delete your account there. Deleting removes your account and everything synced to it, and you choose what stays on your iPhone.
When does Muscla send reminders?
At the moments you choose: morning, midday, evening or around your training. Muscla reaches out on its own at most once a day and never between 22:00 and 8:00. You can change them in the app's notification settings.
