Stopwatch Max Downloads & RevenueStopwatch Max: Lap Timer · App Store

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.
