Fit By Mo is a personal-training app built around one idea: a real coach, with AI that adapts your plan to how you actually sleep, eat, and lift. Train with a program that moves with you. Every session, meal, and check-in feeds back into your week — so your next workout reflects the work you really did, not a template from a book. WHO IT'S FOR • People who've tried gym templates and want something built around their numbers. • Athletes who want their lifts, sleep, and recovery in one place. • Anyone who wants a coach in their pocket without the WhatsApp chaos. WHAT'S INSIDE • Today, in one screen. Your next workout, hydration, macros, steps and weight on the home tab — no tab-hopping mid-session. • Programs that adapt. Push / Pull / Legs, Upper / Lower, sport-specific blocks. The plan re-tunes weekly from your sleep, soreness, and check-ins. • Smart lift tracking. Log reps, RPE, and rest between sets. The app charts your strength curve and surfaces the next progression. • Macros that match the plan. Personal calorie and protein targets recalculated every phase. Photo-log meals or pick from the catalog. • Health connected. Pulls steps, sleep, heart rate, HRV, and workouts from Apple Health and Health Connect — your coach sees the full picture, not just gym logs. • Direct line to Mo. Voice notes, photo check-ins, and questions answered in-app, not buried in a group chat. • Supplements catalog. Curated, evidence-based picks with dose, timing, and warnings. THE METHOD 1. Intake — a 45-minute call with Coach Mohamed. Not a quiz. 2. Program — AI builds the week from your numbers. Mo reviews and edits before it ships. 3. Adapt — every check-in re-tunes load, volume, and rest. The plan moves with you. 4. Own it — you learn the why behind every set. The plan ends. The skill stays. PRIVACY FIRST Your health data is yours. Apple Health and Health Connect samples are encrypted in transit, and only your coach can see your individual numbers. We never sell your data.
