Photo Finish: Sprint Timer

Time sprints and training runs directly from race footage with frame-level precision. Photo Finish: Sprint Timer lets athletes and coaches import a video, step through individual source frames, mark the start cue and finish crossing, and save comparable results on your device.

BUILT FOR TRACK AND SPRINT TRAINING
Whether you are timing a 60 m dash, a 100 m heat, a 200 m bend, or a custom flying-sprint distance, Photo Finish works directly with the video's source presentation timestamps - including variable-frame-rate recordings - without guesswork or frame interpolation.

KEY FEATURES
- Frame-by-frame video review: Step forward or backward one source frame at a time, scrub the visual filmstrip, or play and pause to locate key moments.
- Adjustable finish-line guide: Tap the video stage to align the vertical orange finish marker with the near edge of the finish line, then zoom up to 4x to inspect close torso crossings.
- Precise start and finish markers: Pick the exact frame showing your start cue and the exact frame where the athlete's torso crosses the finish plane. Elapsed times display to the millisecond (0.001 s).
- Distance presets and custom distances: Choose 60 m, 100 m, or 200 m in one tap, or enter any custom distance from 0.01 m to 1,000 m.
- Time multiple athletes from one clip: Open any saved race video and tap Time an athlete to reuse the start marker and score separate finishers in the same heat.
- Ranked comparisons and time gaps: View ranked results by distance with exact gaps behind the fastest run so athletes and coaches can track progress across heats.
- CSV and clip sharing: Export your saved sprint results as a formatted CSV spreadsheet or share saved race videos using the system share sheet.
- No account required: Open the app and start timing right away, with your saved clips and timing library stored privately on your device.

HOW IT WORKS
1. Start a session: Enter the athlete's name, pick a distance, and import an MP4 or MOV race clip from Photos or Files.
2. Mark the start: Step to the first frame showing the start signal or initial movement and tap Set start.
3. Align and mark the finish: Position the orange guide on the finish line, zoom in if needed, step to the frame where the torso reaches the plane, and tap Set finish.
4. Save and compare: Save the timed result to inspect ranked splits, compare heats at the same distance, or export CSV summaries.

NOTE FOR ATHLETES AND COACHES
Photo Finish: Sprint Timer is designed for training and video review. Timing precision depends on camera angle, shutter clarity, and the video's recorded frame spacing. Place the camera steady at the finish line, aimed across the lanes, for the clearest torso alignment.
