Lean, formerly LumaFit, brings strength training, hydration and sleep into one daily routine. TRAIN AND SEE YOUR PROGRESS • Follow built-in routines or create multi-day plans. • Record sets, reps, weight, RPE, cardio and workout notes. • Review personal records, training history, muscle coverage and progress trends. • Use Apple Watch, Live Activities and widgets, with optional iCloud sync. MAKE CONSISTENCY VISIBLE • Track training, water and sleep from the daily dashboard. • Optionally import sleep records from Apple Health after granting permission. • Reveal silver-blue metallic workout reports, review your best sets and share your progress. • Choose whether to include body measurements or hide absolute training weights in shared reports. CAMERA EXAMS AND ACHIEVEMENTS • Try pull-up exams and push-up counting with on-device pose recognition and live landmarks. • Switch between front and rear cameras in the camera screen. • Unlock playful fitness degree achievements, revisit them on the achievement wall, and share landscape certificates or portrait posters. • Camera video for movement recognition is processed on-device and is not recorded or uploaded. Pose counting depends on lighting, camera placement and visibility. In-app fitness degrees are entertainment achievements, not academic degrees or professional certifications. OPTIONAL AI COACHING • Ask training questions or generate editable plans and workout reviews. • Estimate meals from photos or descriptions, then review and confirm before saving. • Two free AI text chats are available each day. Additional AI features require LumaFIT Pro. • Online AI requires an internet connection and consent before relevant data is sent to the disclosed service. LUMAFIT PRO Monthly and yearly auto-renewable subscriptions are available through Apple. Any eligible introductory offer and renewal price are shown before purchase. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your App Store account settings and restore purchases in the app. A LumaFit account is optional. Fitness guidance and meal estimates are for general reference, not medical advice. Stop exercising if you feel pain or unwell. Privacy Policy: https://lumafit.xyz/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

MiloFit is an AI personal trainer app built for strength training. It closes the loop between planning, logging, reviewing, and next-step recommendations — while keeping in-workout logging fast enough to never break your rhythm. — Innovative Logging Interaction Log sets and reps in seconds between sets. Custom exercises, quick reference to past sets, and automatic PR detection. Your history is right in front of you — no flipping through screens to find last time's weight. — AI Coach That Reads Your Training Data The AI coach gives advice based on your real training logs, body metrics, and workout templates — not as a generic chatbot. Ask about exercise technique, key form cues, or injury prevention. After each session, it automatically reviews your progress and weak points. AI can also generate training templates and weekly plans based on your goals and history, but nothing takes effect until you confirm — the AI suggests, you decide. — Body Metrics and Health Data Integration Import height, weight, and body fat from the Health app to personalize recommendations. Completed workouts can optionally be written back to the Health app, and whether to enable estimated active energy is your choice. — Templates and Weekly Plans Save your own training templates for quick reuse, or let AI generate weekly plans based on your goals and training history, adjusted dynamically as you progress. — Your Data Stays in Your Hands Core training data is stored locally first, with optional cloud backup for cross-device sync after sign-in. Export your training, body metrics, and template data anytime from the profile page. Whether you're just starting out or already experienced — if you're into strength training and want less logging friction with more data-driven insight, MiloFit is built for you.
