Complete-rep count
Identify cycles that begin near standing, pass the documented lowest-phase threshold, and return to standing.
Set Replay for iPhone
Measure the set. Skip the verdict.
Choose or record one side-view squat video. Set Replay counts complete rep cycles and reports camera-observed 2D estimates for knee angle, rep time, joint coverage, and within-set consistency.
No account, advertising, analytics, tracking, automatic upload, safety score, or correctness grade.
One observable job
Replay mechanics you can compare.
Set Replay is deliberately limited to after-set side-view squat measurements. It does not diagnose movement, replace a coach, or tell you whether exercise is safe or suitable.
Transparent 2D estimates
See estimated lowest knee angle, descent and ascent time, and the exact thresholds used by the app.
Local set history
Keep measured summaries on your device, compare recorded sets, delete a saved result, or export a clearly labeled CSV.
Private by architecture
Your workout video is not uploaded.
Apple Vision pose detection, rep segmentation, and metric calculation run on your device. Set Replay stores measured summaries in local app storage and has no developer server or analytics SDK.
