MuscleLit Terms of Use
Last updated 13 October 2026
By using MuscleLit you agree to these terms. If you do not agree, please do not use the app.
Not medical advice
MuscleLit shows exercises and plans for general fitness. It is not medical advice, and the camera form check is not a substitute for a qualified coach. Ask a doctor before starting a training programme if you have an injury, a health condition or are unsure, and stop at once if you feel pain. You train at your own risk.
Free features and MuscleLit Pro
The exercise library, the 3D body, starter plans and basic logging are free. MuscleLit Pro unlocks the rest, including the camera rep counter, the mirror, the X-ray layer, muscle balance, the weekly video, share cards, unlimited workouts, your own plan, progress photos and backups.
Pro is sold as a monthly subscription, a yearly subscription, or a one-time lifetime purchase, through Google Play on Android and the App Store on iPhone.
Subscriptions and free trial
- The yearly plan may include a free trial. If you do not cancel before the trial ends, the yearly price is charged.
- Subscriptions renew automatically at the same price and period until you cancel. Cancel at least 24 hours before the end of the current period to avoid being charged for the next one.
- Cancel in Google Play (Subscriptions) or in the iPhone's Settings → Subscriptions. Deleting the app does not cancel a subscription.
- Prices are shown in your local currency in the store before you confirm and may differ by country.
- Refunds are handled by Google Play or Apple under their refund policies.
Lifetime purchase
The lifetime purchase gives Pro on the store account that bought it for as long as MuscleLit is available on that store. It is not a subscription and does not renew.
Your content
Your workouts, photos and settings are yours and stay on your device. You are responsible for keeping a backup. Share cards and videos you create may be shared by you however you like.
Acceptable use
Do not copy, resell or reverse-engineer the app or its 3D content beyond what the licences below allow.

Liability
MuscleLit is provided as is. To the extent permitted by law, Codebage is not liable for injury, loss or damage arising from use of the app.
