Rep Trace is a strength training log and recovery companion built for people who lift. It remembers more than weight and reps. Save machine settings, seat positions, grips, training cues, target muscles, and how each exercise felt. When you return to the gym, your next workout no longer starts from memory. REMEMBER EVERY WORKOUT • Quickly log exercises, sets, reps, and weight • Save machine settings and personal training cues • View your previous workout for the same exercise or muscle group • Track training volume and progressive overload KNOW HOW TO TRAIN TODAY With your permission, Rep Trace uses available Apple Health signals such as sleep, heart rate, HRV, activity, and recent workouts to provide a clear training direction: • Ready to push • Train as planned • Reduce total volume • Prioritize recovery SCAN GYM EQUIPMENT WITH AI Take a photo of an unfamiliar machine to learn its common purpose, target muscles, basic setup, movement cues, and common mistakes. Add useful exercises directly to today’s editable workout plan. REVIEW YOUR PROGRESS Choose a week, month, or custom date range to review workout frequency, training volume, muscle-group balance, progressive overload, and recovery patterns. AI-assisted reviews help identify practical adjustments for your next training phase. TRAIN WITH APPLE WATCH View today’s plan, track the current set, start a rest timer, receive haptic reminders, and check your readiness from your wrist. Rep Trace does not give you another generic workout course. It remembers how you trained, helps you decide how to train today, and makes every workout useful to the next one. Health, readiness, equipment recognition, and AI-generated suggestions are for general fitness information only and are not medical advice. Available Apple Health data depends on your device and permissions. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
