BolTimer is an electronic timing app for track & field and swimming training. Record at a high frame rate, then judge the result frame by frame on your phone. TRACK • Finish-line recording up to 240 fps on supported iPhones • Choose sprint or distance: distance races record the start and splits on a timeline • Flash or sound start detection can mark 0 time automatically; you can also open and warm up the camera first, then record manually. Distance races can be filmed in segments and exported as one video • Frame-by-frame review with up to 8 lanes • Drag a result onto a lane, recalibrate the start frame, fine-tune within ±3 ms • Copy results as text or export video with a timing overlay SWIMMING • One phone follows one swimmer; several phones stay on the same clock by filming the same starting flash • Mark takeoff, entry, breakout, turn touch, turn push and finish frame by frame • Reaction time, flight time, underwater phase, lap splits and total time • Count left and right arm entries separately, with a check for missed or accidental double taps • Stroke count, distance per stroke and SWOLF per lap IMPORT AN EXISTING VIDEO • Pick a clip from your library, choose the start frame yourself, then judge it like a live recording • Slow-motion clips are read at their real capture rate, so times are not stretched • Short clips are prepared for smooth frame-by-frame stepping HOW IT WORKS 1. Auto start: align the flash zone, tap Stand By, recording begins after the gun 2. Manual start: open and warm up the camera, wait until Ready, then tap Record (the start flash must be in the clip) 3.

Copy results or export annotated video to Photos; distance races can merge all clips into one export REQUIREMENTS • iOS 17.0 or later • A real iPhone with a rear camera (the Simulator has no camera); the highest frame rate available depends on your model • Camera and microphone permission for timing; photo library permission only when you import or export a video DATA & PRIVACY No account and no sign-in.
