Round Timer: Boxing & HIIT

Round Timer is a simple, reliable interval timer for boxing, HIIT, Tabata, MMA and circuit training. Set your work time, rest time and number of rounds — then just train. The huge display and full-screen colors (green = work, red = rest) are readable from across the gym, and the loud bell cuts through your music without stopping it.

No ads during your workout. Ever.

Features: ready-made presets (Boxing 3:00/1:00 ×12, Tabata 20/10 ×8, EMOM, HIIT) — precise timing even with the screen off — bell, beep and whistle sounds with volume ducking — vibration alerts — keep-screen-on option — dark theme.

Whether you are hitting the heavy bag, doing a HIIT session or timing your circuit training, this round timer keeps you on schedule.
