Movement Tracker+

Movement Tracker+ is a native iOS app (SwiftUI, Swift 6, iOS 27) for people who train alone, at home or in a dorm gym, without a coach. It watches your set through the iPhone camera, counts every rep on-device, measures depth, tempo and fatigue per rep, and has Meta's Muse model turn those numbers into coaching, plans and nutrition logging. How it works: - Frame yourself side-on with the front or back camera. Counting starts only once the joints the exercise needs are confident, clear of the frame edge and held for a second. - Live set: reps, partial reps and a depth gauge update on-device, with at most one spoken cue per rep. Built-in exercises: bodyweight squat and push-up. - Set review: per-rep measurements first, then a Muse review that cites reps by number. - Coach chat: answers from your own training and nutrition data through on-device tools; plans and meals come back as proposals you confirm. - Meal photo: Muse names the foods and estimates grams, USDA FoodData Central supplies the nutrients, you edit and save. - Today: the day's nutrition, latest workout, weight trend, and a readiness estimate from Apple Health recovery readings with a suggestion to train, go easy or rest. - Teach a new exercise by demonstration: do a few reps and say how many; it is saved as a counted exercise only if replaying the demonstration through the engine reproduces that count. Also shipped: workouts, meals and weight written to Apple Health; a Live Activity for the workout in progress; App Shortcuts and Siri; rest alerts; English and Simplified Chinese. Muse never counts reps. The on-device numbers are the source of truth; Muse explains them.
