Multi-Timer; Stopwatch & Timer7.4.0 - App Store

All basic features are available for free!

Perfect for coaches, athletes, and anyone who needs to measure multiple times simultaneously!

As a runner myself, I created this app from the perspective of athletes and team managers who want precise and flexible timing tools.

A multi stopwatch and interval timer for team managers, race timing, training, games, business time tracking, and anyone who needs to time multiple people or events at once.

Built for track & field, swimming, cycling, motorsport, fitness training, games, work-from-home billing, and everyday timing. Record lap and split times, manage multiple stopwatches, save results, and review past sessions in the calendar.
