Lift. Sip. Sleep. Repeat. Lean makes the everyday stuff feel like progress. Log sets, reps, weights, RPE and cardio. Follow routines, review personal records and muscle coverage, and track nutrition, water and sleep. Apple Health sleep import and iCloud sync are optional. Your effort has a counter: try on-device pull-up exams and push-up practice, with live joint landmarks and front/rear camera switching. Camera frames are processed on-device, without recording or upload. Counting depends on lighting, framing and visibility. Six pull-ups can unlock the first playful fitness degree. Revisit achievements and share certificates, posters or metallic workout reports with privacy controls. These degrees are in-app entertainment achievements, not academic or professional qualifications. Optional AI coaching answers questions and helps create editable plans, workout reviews and meal estimates. Review estimates before saving. Each week, nonmembers get 2 AI text chats and 1 food-photo calorie estimate. Both reset Monday at 00:00 Beijing time; unused credits do not carry over. Other AI generation requires LumaFIT Pro. Online AI requires an internet connection and consent before relevant data is sent to the disclosed service. LumaFIT Pro offers monthly and yearly auto-renewable subscriptions. Prices and any eligible offers appear before purchase. Payment is charged to your Apple Account at confirmation. Renewal is automatic unless cancelled at least 24 hours before the current period ends. Manage or cancel in App Store settings; restore purchases in the app. A LumaFit account is optional. Store text is localized; the app currently includes Chinese and English, and some screens remain in Chinese. Fitness guidance and meal estimates are for general reference, not medical advice. Stop if you feel pain or unwell. Privacy: https://lumafit.xyz/privacy Terms: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
