Centisecond-accurate timer using date-based calculations. Survives app restarts.
Apple Watch stopwatch app
Precision timing on your wrist.
Stopwatch Max is an Apple Watch stopwatch app built for people who need more than a simple start and stop timer. It helps you capture laps quickly, keep timing accurate when your wrist is down, and control the stopwatch when touching the screen is inconvenient.
It is useful for runners, coaches, interval training, gym sessions, study sprints, cooking, and any situation where a wrist-based stopwatch is more convenient than reaching for a phone.
