About fitness timers
Interval training is one of the most time-efficient ways to improve fitness. Whether you're doing HIIT (High-Intensity Interval Training), classic Tabata, or CrossFit-style EMOM and AMRAP workouts, having a reliable timer with audio cues lets you focus on your exercise instead of watching the clock.
Each timer on this page is pre-configured with the correct work/rest ratios for its training style. Audio alerts play between intervals so you can keep your eyes on your workout. Works on any device — no app needed.
Frequently asked questions
What's the difference between HIIT and Tabata?
Tabata is a specific type of HIIT with a fixed protocol: 20 seconds work, 10 seconds rest, 8 rounds (4 minutes). HIIT is broader and can use any work/rest ratio — commonly 40/20 or 30/15.
Can I use these timers in the gym?
Yes! These timers work in any browser on your phone, tablet, or laptop. The audio alerts play through your device speakers or headphones so you can hear them during your workout.
How many calories does a HIIT workout burn?
A typical HIIT session burns 200-400 calories in 15-30 minutes. The real benefit is EPOC (excess post-exercise oxygen consumption) — your body continues burning extra calories for hours after the workout.
