Workout and sports timers

Timers built for interval training, boxing, martial arts, and functional fitness workouts. Each tool runs in your browser with no sign-up, recovers correctly after background tabs and refresh, and saves your configuration locally.

Start a new interval every minute with configurable rounds, optional custom intervals, activity labels, and sound at boundaries.

Boxing Timer

Configurable boxing round timer with preparation, round and rest durations, warning before round end, and optional sounds.

Martial Arts Round Timer

Build editable training sequences with named drills, variable durations, optional rest steps, and sequence repetition.

Understanding EMOM and AMRAP

EMOM stands for Every Minute on the Minute. A new interval starts automatically at the top of each minute. You perform your exercise within that minute, and the next round begins on schedule without requiring you to mark anything complete.

AMRAP stands for As Many Rounds or Repetitions as Possible. You set a total workout duration, and during that time you complete as many rounds or repetitions as you can. The round counter is manual — you enter your completed rounds and optional partial repetitions yourself.
