A PERSONAL TRAINER IN YOUR POCKET, GENERATED DAILY. A real trainer charges $60 to $100 an hour. A static workout app hands you the same eight-week block whether you slept four hours or eight, whether your shoulders are wrecked or fresh, whether your gym has a squat rack today or not. KeyLifter fixes both. Every day, it generates a new workout for you based on how the last session went, how recovered each muscle group is, what equipment your gym actually has, and where you are in your progression on every lift. Progressive overload happens without spreadsheets. Deloads happen when your body needs them, not when a static program says so. WHY THIS IS DIFFERENT FROM EVERY OTHER GYM APP • It writes the workout. You don't pick a template, you don't fill in sets and reps — you open the app and the day's session is there. • It adapts. Logged a brutal squat day yesterday? Today's leg work backs off. Felt fresh on bench? It pushes the next session harder. • It knows your gym. Save the equipment at every gym you train at. Traveling? Switch profiles and the day's program reworks in seconds. • It tracks recovery, not just volume. Per-muscle freshness scores tell you what's ready to train and what needs another day. INSIDE THE APP WORKOUT Today's session, written for you. Full-screen player with rest timers, RPE logging after each set, and progressive overload flags on every lift so you know exactly what to beat. RECOVERY A body map showing freshness scores for every muscle group. See at a glance what's recovered, what's still cooking, and why the AI programmed today the way it did. HISTORY Every session, every lift, every PR. Watch your bench, squat, deadlift, and accessory work trend up over weeks and months — not as a graph you have to interpret, but as a clear signal of what's working. PROFILE Your goal (strength, hypertrophy, body recomp, weight loss), your experience level, your current lifts, your gym equipment profiles. Change any of it and tomorrow's workout changes with you. WHO THIS IS FOR • Lifters tired of paying $200 to $1,000 a month for a coach to text them a Google Doc • People who've cycled through three apps and a dozen YouTube programs and still don't know what to do today • Travelers and multi-gym members who waste half a session figuring out substitutions • Beginners who need a real plan with real form cues — not a generic template • Advanced lifters who want periodization that actually responds to their recovery PRICING Free: one AI-generated workout per week, one equipment profile, basic progression tracking. Try the magic before you pay. Pro ($9.99/month or $79.99/year): daily AI workouts, unlimited gym profiles, recovery-aware programming, body-map targeting, supplement and nutrition tracking. Less than one session with a human trainer, for a month of programming that adapts every single day. Download KeyLifter, answer a few questions about your goal and your gym, and open tomorrow's workout.
