TapSplit is a no-nonsense stopwatch built for coaches and athletes who need to trust their timing. TAP ANYWHERE — START, LAP, RESUME The whole screen is your button. Tap to start, tap for every lap (zero debounce — every touch counts), tap to resume after a stop. Each tap fires a crisp haptic. No tiny targets, no missed splits — just keep your eyes on the athlete. LAP & SPLIT AT A GLANCE See each lap time and its cumulative split side by side, with a running BEST / AVERAGE / WORST strip so trends jump out at a glance. PLAN YOUR SETS Save a set like 8×100m on 1:30 and load it onto the stopwatch. TapSplit counts the reps and shows live "Rep 3 of 8" progress, so you just tap the splits — no counting in your head. Give the set a send-off interval and it counts down to your next rep during the rest, buzzing when it's time to go — a real interval trainer. Keep a reusable library of your go-to sets, each with its own note. TIME YOUR WHOLE SQUAD Switch the stopwatch to Multi mode and give every athlete their own clock on one screen. Save your athletes once and drop them onto lanes — no retyping names. Start them all together for a mass start, or each one as they go. Every athlete's run saves as its own session, just like the single stopwatch. STROKE RATE IN A FEW TAPS Press and hold while you count a few cycles — strokes, steps, or pedal strokes — and release. TapSplit times the hold and gives you the rate per minute. Measure mid-session and it pairs with the lap you took it on, so rate sits right beside that length's split. REVIEW EVERYTHING IN HISTORY Every session is saved the moment you start — there's no Save button to forget. Filter by stopwatch, set, or athlete, search your sessions, and browse them grouped by day. Rename sessions and add notes. ROCK-SOLID ACCURACY TapSplit runs on a monotonic clock that never drifts — accurate across stop and resume, and it keeps running even when your phone is locked or the app is in the background. SHARE YOUR DATA Export any session as a clean text or CSV file — or select several and share them all as one combined file. Save to Files, AirDrop, or email straight from the share sheet. PRIVATE BY DESIGN No accounts. No analytics. No network requests. Everything stays on your device, full stop. FEATURES • Tap anywhere to start, lap, and resume — zero debounce • Single, Multi, or Sets mode — one stopwatch, one per athlete, or a planned set • Training Sets — save and reuse planned sets, with live "Rep N of M" progress • Send-off intervals — a live countdown to the next rep, turning Sets into an interval trainer • Reusable saved athlete list • Stroke-rate (SPM) measurement, paired to each lap • Pro controls: Lap / Stop, Start / Reset • Live current-lap time, plus BEST / AVG / WORST • Millisecond precision (MM:SS.hh), rolls over to hours for long efforts • Auto-saved sessions — filter, search, and browse grouped by day • Editable session titles and notes • Undo lap deletions; duplicate and prune sessions • Text or CSV export — per session, or several combined into one file • Light / Dark / System appearance • Haptic feedback (with on/off toggle) • Screen stays awake while timing Whatever the sport, TapSplit keeps the timing honest and out of your way.

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. Step through frames and mark the moments you need 4. 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.
