Multi Stopwatch Lap Timer
Run 10 stopwatches at once, with full lap history
Multi Stopwatch Lap Timer runs up to 10 independent stopwatches on one screen, so you can time multiple runners, exercises, or tasks at once instead of juggling separate apps. Start and stop each timer on its own, or control all of them together with Start All / Stop All. Every stopwatch records its own laps and splits with the best lap highlighted automatically, and a full session - all 10 timers, every lap - saves to History, filterable by activity. Free, works offline, no account required.
Hi Product Hunt,
I'm a solo developer from Japan. I built Multi Stopwatch Lap Timer because every stopwatch app I could find only tracks one thing at a time - and real timing situations (a running club, a HIIT circuit, a relay, three things cooking at once) usually involve more than one.
So the whole app is built around running several stopwatches at once:
- Up to 10 independent stopwatches on one screen, each with its own start/stop/lap.
- Start All / Stop All to control every timer together when a set begins or ends.
- Every stopwatch keeps its own lap and split times, with the best lap highlighted automatically.
- When you're done, the whole set - all 10 timers, every lap - saves as one Session, so you can pull up last Tuesday's sprints or last week's intervals later instead of losing the numbers.
- No account, works fully offline, and it asks before you can switch away mid-timing, so you don't lose a running stopwatch by accident.
It's free to use, with a small ad shown in the footer.
I'd love to hear from anyone who's tried to time more than one thing at once with a phone - what does your setup look like today, and what's missing?
