## What is BolTimer?

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
• Flash or sound start detection marks the start moment automatically
• 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. Align the flash detection zone and tap Stand By
2. After the start signal, BolTimer records automatically
3. Step through frames and mark the moments you need
4. Copy results or export annotated video to Photos

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. Recordings and results stay on your device and are not uploaded to our servers.

MEMBERSHIP
Free sessions included. An optional paid 7-day pass or a one-time lifetime purchase unlocks unlimited use. Both are one-time purchases, not auto-renewing subscriptions. Purchases are processed by Apple.

## Version history (last 2 releases)

### 1.1 — 2026-08-12

Swimming training mode and video import.

• Swimming mode: mark takeoff, entry, breakout, turns and finish; reaction time, lap splits, left/right stroke counts, distance per stroke and SWOLF
• Import a video you already shot, set the start frame yourself, and judge it in track or swimming mode
• Slow-motion clips are read at their true capture rate instead of a stretched 30 fps timeline
• Race History now shows the frame rate each race was actually captured at
• Detection is paused while you are judging, so a nearby whistle can no longer start a recording behind your back
• New "Next race" button: store the clip and arm for the next start right away, then judge everything later

### 1.0 — 2026-07-10

No release notes.
