Stopwatch Max vs TapSplit

The stopwatch built for your wrist — now on your phone too. Stopwatch Max is a precision lap timer designed for Apple Watch, where it runs entirely on its own, with a full iPhone app that stays on the same run. Raise your wrist and go. TRACK EVERY LAP Capture every split with pinpoint accuracy. Record laps with a tap, a double-tap, a hand gesture on Apple Watch, or automatically at an interval you set — whatever feels right in the moment. Every split is logged instantly and displayed in real time, so you always know exactly where you stand. WATCH AND IPHONE, ONE RUN Start a run on your wrist and see it tick on your phone. Laps, elapsed time and the running state mirror across both devices, and a finished run lands in the history on each one. Use either device alone, or both together. YOUR SESSION HISTORY Every run is saved — laps, splits, date, and your average and maximum heart rate. Open any session to see the full lap list exactly as you recorded it. HEART RATE, LAP BY LAP Turn on heart-rate recording and your Apple Watch captures your heart rate at the moment you take each lap, not just the average and maximum for the whole run. See how you climbed, and where you recovered. SHARE AND EXPORT On iPhone, send a run as a clean summary, export it as a CSV for your spreadsheet, or share it as an image card with a chart of your splits, your average line and your fastest lap highlighted. HEALTHKIT WORKOUTS With heart-rate recording on, every timing session on Apple Watch is logged as a workout in Apple Health, with lap events recorded as activity milestones — a structured log of every run. Leave it off and Health is never asked for. SIRI SHORTCUTS Your hands are busy. Start, lap, pause, resume and reset — all hands-free with Siri, from anywhere, at any time. Whether you're mid-rep, mid-lap, or mid-race, your voice is all you need. WATCH COMPLICATIONS Add Stopwatch Max to any watch face and launch it instantly with a single tap — no swiping, no searching. Have your stopwatch ready the moment you need it. TUNED TO YOU Set an auto-lap interval, choose your display refresh rate, and feel a lap without looking — on Apple Watch the lap haptic comes in Light, Medium and Strong. BUILT TO LAST Your timer state is saved automatically in the background. Switching apps, checking a notification, or restarting your watch won't cost you a single second. Come back to your stopwatch exactly as you left it. WORKS IN YOUR LANGUAGE Fully localized in English, German, Spanish, French, Japanese, Russian, and Simplified Chinese. PRIVACY FIRST No ads. No subscriptions. No data collected. A one-time purchase that respects your time and your privacy. Simple enough for your first workout. Precise enough for your best one.

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.
