RepZero is a weight lifting log and gym workout tracker for iPhone and Apple Watch. Log every set in seconds, see your records the moment you break them, and always know what to train next. It's built for people who want to know they're getting stronger, not just hope they are. LOGGING THAT KEEPS UP WITH YOU RepZero shows one set at a time: tap 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. • 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 • 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 Follow a program and RepZero plans every session and raises your weights as you progress. Beginner Strength and Dumbbell Foundations are free. Upper/Lower Hypertrophy, Push/Pull/Legs, Strength Waves and Minimalist come with Pro, and so does building 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 • 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 or build your own in minutes, and share routines and programs with a link. Bring your history from other apps with an AI-assisted import. Back up to iCloud, sync across devices with a free account, and export your data anytime. REPZERO PRO Pro is for lifters who want a plan, not just a log. • 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. • All six programs, plus programs you build yourself • Lift forecasts, strength levels and muscle balance • Unlimited custom routines (free includes 5) • Body measurements, Lift and Progress widgets, and premium themes • The Gainz Goblin: a pixel-art pet on your Today screen, Watch and Live Activity. Train and he stays fed. Skip too many days and he gets hungry. WHOEVER YOU ARE Chasing your first bodyweight bench, running a powerlifting block or just trying to get to the gym three times a week, RepZero shows you it's working and what to do next.
