KasMaker is a workout tracker built around a muscle map, not just a gym logger. Log your sets and an interactive body map fills in โ€” primary and secondary muscles โ€” so you see exactly what you trained, what is still fresh, and what to train next. A free strength training log with 800+ exercises, automatic personal records, supersets, a plate calculator, and a rest timer. TRACK EVERY MUSCLE Your body map fills in as you log. See at a glance which muscles are worked, which are fresh, and which you keep skipping. Tap any muscle to dig into its training history and top exercises filtered by your equipment. LOG WORKOUTS YOUR WAY Pick from 800+ exercises with instructions and images. Repeat a past workout in one tap, start from a saved routine, or build from scratch. Step away and come back โ€” your session picks up right where you left off. AUTOMATIC PR DETECTION Personal records are caught the moment you log them. The first set at a new weight gets highlighted, so a milestone never slips by. REST TIMER Built-in rest timer that auto-starts when you finish a set and stays out of your way between exercises. Adjust the duration to fit how you train. SUPERSETS Link exercises to run back to back. Grouped exercises are badged in your log, and the rest timer waits for the end of the round instead of firing mid-superset. PLATE CALCULATOR Tap Plates on any barbell exercise and see exactly what to load per side โ€” pick your bar, get the breakdown. No more gym math between sets. SET TYPES, WARM-UPS & RPE Mark sets as warm-up, drop set, or to failure. A warm-up calculator ramps you to your working weight, and warm-ups never inflate your PRs or recovery. Rate effort (RPE or RIR) to sharpen recovery estimates โ€” off by default. APPLE HEALTH Optionally save every finished workout to Apple Health, so your lifting counts toward your activity. HOME SCREEN WIDGETS Your muscle map, right on your home screen. See what's fresh and what's still recovering without opening the app. Small and medium sizes. LIVE ACTIVITY & DYNAMIC ISLAND Run your whole workout from the Lock Screen and Dynamic Island โ€” timer, current exercise, set progress. Complete sets and save your workout without unlocking your phone. MAKE IT YOURS Light, dark, or follow the system โ€” plus an accent that runs through the whole app, muscle map included. BUILT FOR PRIVACY Your data lives on your device. iCloud sync is optional, and no account is required. No analytics. No tracking. No ads. Ever. MUSCLE RECOVERY โ€” PRO Every muscle gets a readiness state โ€” fresh, recovering, or fatigued โ€” computed from your logged sets, your effort ratings, and each muscle's recovery window. Open the app and know exactly what's ready to train. SMART TRAINING INSIGHTS โ€” PRO Push/pull balance, recovery status, volume trends, compound-vs-isolation mix, and progressive-overload targets โ€” all generated from your own data, with no black boxes. Free includes your first insight; Pro unlocks all five. PROGRESS CHARTS โ€” PRO Watch weight and estimated 1RM climb over time for every exercise you train. KASMAKER PRO Start completely free: workout logging, 800+ exercises, the body map, PR detection, the rest timer, supersets, the plate calculator, set types, the warm-up calculator, RPE/RIR, Apple Health, widgets, Live Activity, and your first training insight. KasMaker Pro unlocks the analytics layer โ€” muscle recovery, per-exercise progress charts, all five training insights, and CSV export of your full history. โ€” Subscription Terms KasMaker Pro is offered as an auto-renewable subscription (monthly or yearly) or a one-time lifetime purchase. Payment is charged to your Apple ID at confirmation. Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings.
