Overview
This one I did alone, from the idea to the App Store. The camera counts your reps while you train, using pose estimation from Vision and a CoreML classifier I trained myself. The AI coach reads your sessions and routines and tells you how you are doing, and it runs on the phone with Apple Foundation Models, so nothing leaves the device. If the iPhone has LiDAR it also scans body measurements. Around that there is session logging, saved routines with a weekly schedule, personal records, progress charts with Swift Charts and a backup to iCloud Drive every 6 hours. Clean Architecture inside: MVVM, repositories, use cases and a DI container, SwiftData for persistence and only Apple frameworks, nothing from third parties.
