RepZero is a weight lifting log and gym workout tracker for iPhone and Apple Watch, and every lifting feature is free. Log every set in seconds, see your records the moment you break them, and always know what to train next. LOGGING THAT KEEPS UP WITH YOU Tap an exercise and log one set at a time: dial in your weight and reps, log it, and the rest timer starts on its own. Supersets, drop sets, timed holds and cardio all work the way you'd expect. • Load guidance: a zone bar shows how the weight you dial in compares with your own best, from building muscle to max effort • Plate calculator: which plates go on each side of a barbell, trap bar, EZ bar or Smith machine • Warm-ups in one tap, ramping up to your first working set • Animated how-to guides for barbell and dumbbell lifts • Rest timer on your Lock Screen and in the Dynamic Island, with skip and log buttons • New personal records show up live, mid-workout • Start a workout from a widget, Control Center, Siri or Shortcuts BUILT FOR APPLE WATCH Leave your phone in your bag. Start a workout on your wrist, turn the Digital Crown to set weight and reps, and double tap to log. Heart rate and calories go to Apple Health, and everything syncs back to your iPhone. PROGRAMS THAT MOVE YOU FORWARD Tell RepZero your goal, how you train and the equipment you have, and it picks a plan for you and takes you straight to your first set. Follow a program and RepZero plans every session and raises your weights as you progress. All six programs are free: Big Lifts, Dumbbell Foundations, Upper/Lower Hypertrophy, Push/Pull/Legs, Strength Waves and Minimalist. You can also build your own program from your routines. AN AI COACH IN YOUR POCKET Ask the AI coach about your training, from what to train today to building a new routine. It runs on device with Apple Intelligence on supported iPhones. SEE YOUR PROGRESS, CLEARLY • Estimated 1RM, PRs and records for every lift • Volume, workout and training-time trends • A weekly goal with streaks that give you credit for rest days • Body weight and body measurements • Muscle recovery at a glance • A full history of every workout, as a list or a calendar • Achievements that reward consistency START STRONG, STAY ORGANIZED Use a ready-made routine, including no-equipment Bodyweight Basics, or build as many of your own as you like, and share routines and programs with a link. Bring your history from other apps with an AI-assisted import. Back up to iCloud every day, sync across devices with a free account, and export your data anytime. REPZERO PRO Pro adds a training partner, a coach and a look of your own. • The Gainz Goober: a pixel-art partner on your Today screen, Watch and Live Activity that levels up with every workout and grows into new forms • Weekly challengers: each week a new Goober steps into the arena with its own taunts and signature move. Every workout you finish knocks a chunk off its health bar: empty it before the week ends to win • Coach: ranked next steps after every workout, like adding sets to a lagging muscle or breaking through a plateau, applied to your routines in one tap • Recovery check: reads last night's sleep, heart rate variability and resting heart rate from Apple Health and suggests going lighter or taking a rest day. Those readings never leave your device. • Lift forecasts, strength levels and muscle balance • Lift and Progress widgets, and premium themes, including Forge Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://darkmatterlabs.app/privacy
