A referee in everyone’s pocket.
Live capture, a server-coordinated clock, sealed evidence and a transparent report. Try the interface below. The challenge is 20 pushups. The footage is a real clip, and the count below comes from running it through Pontaro’s computer-vision pipeline (MediaPipe pose → elbow angle → repetition state machine). It found four complete reps, so the challenge fails.
- ◆Server-side start/stop timestamps
- ◆Randomised on-camera phrase makes replays harder
- ◆SHA-256 integrity hash recomputed by the server
- ◆Explicit limits: capture can’t make manipulation impossible

Historical demonstration, not a live session. This replays the stored output of the pipeline run on this clip on 2026-11-02 (mediapipe pose_landmarker_full, tracking confidence 89%, evidence quality high). Real sessions are analysed after upload and the Referee states its uncertainty. Accuracy beyond this small test set is unmeasured.
