Strength Training Performance Tracker for iOS.
Tap 'New Session' to log a strength training workout. Enter the session name, date, warm-up and warm-down minutes, then add exercises with sets, reps, weight, and RPE for each set you complete.
Choose from the built-in exercise library or create custom exercises. For each exercise, log multiple sets with weight, reps, and RPE (rate of perceived exertion). The app calculates total volume and estimated 1RM (one-rep max) using the Epley formula.
Create reusable workout templates to quickly start sessions with your typical exercises pre-loaded. Templates save time when logging recurring workouts.
Strength Coach Analysis automatically calculates total session volume (sets × reps × weight) and estimated 1RM for each exercise. Track how your strength progresses over time.
Strength Coach Pro unlocks per-exercise trend analysis, showing how your volume, 1RM, and RPE change over time for each exercise.
Export and share your training reports via the iOS system share sheet. Reports include session summaries, exercise breakdowns, and progress metrics.
Update your name, age, body weight, height, sport, position, and weight unit preference anytime from the More tab → Edit Profile. All fields entered during onboarding are editable.
Strength Coach Analysis can save your strength workouts to Apple Health as traditional strength training workouts. The app also reads body mass, biological sex, and date of birth from HealthKit to personalise your reports, as well as sleep analysis, HRV (SDNN), and resting heart rate for recovery scoring. HealthKit access is optional — you can decline and use the app fully without it.
Your workout data is stored locally on your device using SwiftData. No personal data or workout results are sent to any server. You can delete all data at any time from Settings → Reset All Data.
