Round Timer

Boxing round timer · MMA · Muay Thai · sparring

Train. Don't watch the clock

Round Timer runs your rounds, rest and get-ready, and rings a boxing bell at every switch. You hear it over your music — even in silent mode.

Free · iPhone on iOS 18+ · no sign-up

This is what a round looks like

Without a timer

Keeping time isn't your job mid-round

  1. 01A phone alarm pauses your music — or gets lost under it.
  2. 02The screen locks mid-round and you lose track of time.
  3. 03Free timers run ads right in your rest break.
  4. 04You keep the round count in your head.

How it works

Listen for the bell. Forget the screen

Over your music

The bell plays alongside your playlist: the music never stops or ducks.

In silent mode

You hear the bell even with your iPhone on silent.

Screen stays on

During a workout your iPhone won't sleep — the time is there at a glance.

Phase colors read from afar

Orange — get ready, lime — round, blue — rest.

The app

The whole workout on one screen

  1. 1Rounds, round length, rest and get-ready in one sheet

  2. 2One big Start button and the total time

  3. 3Huge digits, a progress ring and round pips

  4. 4Finish — or Continue with no round limit

Start in seconds

No sign-up, no account, no tutorial. The app opens straight on the timer with the standard plan ready — three 3:00 rounds with a minute of rest. Tap Start: the bell rings after a 10-second get-ready.
