Photo finish app

Capture professional, high-precision photo-finish results for any race using just your smartphone!

Photo Finish Stopwatch turns your device into a powerful timing tool using the same slit-scan technology used in professional sports. Get definitive proof and accurate times down to 0.05 seconds. No more disputes - see the winner cross the line.

KEY FEATURES:
- High-Precision Timing: Measure finish times with an accuracy of about 0.05 seconds.
- Visual Proof: Generate a time-stamped slit-scan image that clearly shows the finish order.
- Save and Share: Save the photo-finish image or a video of the moment. Easily share results with athletes, parents, or officials.
- Determine Winners: Instantly resolve close races with frame-by-frame analysis.

HOW IT WORKS:
The app continuously photographs a narrow slit of the finish line, stitching each slice into a single image. Every part of this final image has a precise timestamp. Simply scroll the picture to the exact moment an athlete crosses the line to see their official time.

EASY TO USE:
1. Align the camera guide line with the finish line.
2. Start the stopwatch when the race begins.
3. Tap Record as athletes cross the finish line.
4. The app automatically captures image and video from 2 seconds before and 2 seconds after the button press.
5. Scroll the resulting image to find the exact finish time for each competitor.

ADVANCED FEATURES FOR PROS:
- Stopwatch Sync (NTP): Synchronize race start time across multiple devices using NTP. Set one phone as the server and others as clients to capture multiple angles in sync.
- Precise Start Time: If you miss the start, record the starting gun (sound and flash), find the exact start frame, and copy its timestamp as the official time zero.
- Starting Gun Mode: Use your device to start the race with a loud sound and camera flash.
- Remote Control: Place your phone on a tripod and use volume buttons, a Bluetooth remote, or a headset to control stopwatch and recording.
- Full Control: Adjust slit width, recording direction, and other settings; review saved finishes in gallery; pinch to zoom for close calls.

Stop guessing. Start timing. Download Photo Finish Stopwatch and bring professional accuracy to your next race.
