About this app

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 your 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 IT'S DIFFERENT FROM EVERY OTHER GYM APP
• It writes the workout. No templates, no filling in sets and reps — open the app and today's session is there.
• It adapts. Brutal squat day yesterday? Today's legs back off. Felt fresh on bench? Tomorrow pushes 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. A 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 what's recovered, what's still cooking, and why the AI programmed today the way it did.

HISTORY & MILESTONES — Every session, every lift, every PR. Watch your bench, squat, deadlift, and accessory work trend up, and celebrate milestones as you hit them.

SUPPLEMENTS — Track your supplement and nutrition stack alongside your training, so the whole routine lives in one place.

PROFILE — Your goal (strength, hypertrophy, body recomp, weight loss), experience level, current lifts, and gym equipment profiles. Change any of it and tomorrow's workout changes with you.

WORKS WITH YOUR WORLD
• Health sync — workouts sync to your health data so it all stays in one place.
• Your music — connect Spotify and control your soundtrack without leaving the session.

WHO IT'S FOR
• Lifters tired of paying for a coach who just texts them a Google Doc
• People who've tried a dozen programs and still don't know what to do today
• Travelers and multi-gym members who waste half a session on substitutions
• Beginners who need a real plan with real form cues
• Advanced lifters who want periodization that responds to their recovery
