A round timer that sounds like a corner, not an app.

Free round timer for boxing, MMA, Muay Thai, kickboxing and general interval training. Set your prepare, round and rest times, pick how many rounds, and go — real bell and gong sounds mark every phase, so you can stop watching the screen.

Prepare, round, rest — however you train

Every session runs through the same cycle: Prepare to get set, Round to work, Rest to recover. Set the count and duration of each independently, for up to 500 rounds — sparring, pad work, bag rounds or long interval sets all fit.

See it from across the room

The whole screen changes color with the phase, so you can read your status at a glance from the other side of the gym: black through prepare and rest, green through the round, red for the final 10 seconds, and gold when the session is finished.

Real bell and gong sounds

Rounds start and end with real bell and gong sounds, not a generic beep, plus a warning rattle 10 seconds before a round ends — the same cue you'd get from a corner.

Switch and random signals

Two optional signals for drills that need more than a straight round:

Switch signal — splits a round into equal segments and sounds a signal at each boundary, for switching partners, stances or drills mid-round.
Random signal — fires at random moments during the round, for reaction drills where you can't predict the cue.

English and Ukrainian

The interface is available in English and Ukrainian, switchable from inside the app at any time.
