MakeFit: Body Age Tracker

Your workouts are changing your biological age. MakeFit shows you exactly how. Every session, every night of sleep, every rest day — tracked and scored against your Body Age, a real-time fitness indicator built from VO2 max estimates, heart rate recovery, sleep consistency, strength volume, and training zone distribution. JOIN YOUR COMMUNITY Compare your biological age and aging rate on shared leaderboards. See who's improving fastest. Get personalized recommendations based on real health data, not algorithms optimized for engagement. DAILY READINESS & RECOVERY Vitals scores combine sleep quality (duration, efficiency, consistency) with daytime recovery signals so you know whether to push or rest before you start. TRAINING THAT ADAPTS The workout recommender adjusts daily and weekly targets to your actual recovery state — cardiovascular, strength, and rest balanced against your fitness trend, not a fixed plan. AI FITNESS COACH — FULLY ON DEVICE On supported devices with Apple Intelligence, your health coach processes everything locally. Nothing leaves your phone. No cloud, no profile, no exposure. ADVANCED WORKOUT ANALYSIS Heart rate zones, training distribution, heart rate recovery curves, 42-day fitness trend with projection. Every metric feeds back into Body Age. SLEEP DEFICIT TRACKING Cumulative 3-day sleep deficit model with visual alert. Bedtime notifications use fresh, context-aware data — not a fixed schedule. — MakeFit is not a medical device.
