A round timer built for combat sports
Whether you're hitting pads, sparring, drilling Brazilian Jiu-Jitsu or grinding through a conditioning circuit, this free round timer keeps the session honest. Set your work and rest periods, choose how many rounds, and let the bell run the clock so you can focus on the work instead of watching a stopwatch.
Presets for every discipline
- Boxing timer: the classic 12 × 3-minute rounds with a one-minute rest.
- MMA timer: 3 or 5 five-minute rounds, just like a UFC main card.
- BJJ timer: longer rolls with short rests for open-mat rounds.
- Tabata & HIIT: 20s-on/10s-off and other interval-timer formats for conditioning.
Need something custom? Set any number of rounds and any work/rest length in the builder — it doubles as an all-purpose interval timer for circuits and stretching.
How to use the round timer
Choose a preset or dial in your own rounds, then tap Start. A short prep countdown gives you time to glove up, then the bell rings to open round one. Warning beeps sound in the final seconds so you can empty the tank, and the timer automatically rolls into the rest period before the next round. Tap the bell icon to mute, or reset any time.
When you're done sweating, test your fight knowledge on the UFC quiz, or learn the BJJ belt ranks.
