Clean design, instant load, and practical features you’ll actually use. Whether you’re doing sprints, circuits or EMOM strength sets, this tool keeps you on pace without distractions.
Smash your workouts with a simple, fast interval timer that runs right in your browser. Choose ready-made presets like Tabata, HIIT and EMOM, or build your own with warm-up, work, rest, rounds and cool-down. It’s mobile-friendly, loud enough to hear the beeps, and flexible enough to run multiple timers at once. No downloads, no sign-up — just set your intervals, press Start and train.
