About
Read the full description
LazyFit is an iPhone app of short standing workouts, three, five or eight minutes long. Hold the phone at your chest, in your hand or overhead and its motion sensors count your reps, while a voice and gentle haptics keep the tempo. No camera, no equipment, nothing on the floor. Nine standing moves, streaks, widgets and Apple Health logging if you want it. The app is free with no account, no ads and no tracking; an optional one-time Pro purchase adds custom workouts and programs. iOS 17 or later.

Could you build this?
Partial The UI, timers, voice, and haptics are straightforward SwiftUI and CoreMotion work, but reliable rep counting from phone motion across different users and grips needs signal-processing tuning and real test data.
What it would actually take: The stack would be native Swift with CoreMotion for accelerometer and gyroscope streams, a peak-detection or rep-classification layer, and AVSpeech plus Core Haptics for cues. The hard part is making rep detection accurate across body positions and users, which requires collecting labeled motion recordings and tuning thresholds or a small classifier. Someone with mobile sensor-signal experience and a test panel of real users would be needed.
