Boxing Timer
A boxing timer calls your rounds for you, with a bell at the start and end of each. This one is set to twelve 3-minute rounds with 1-minute rests - Change the round length, rest and count to match your session, then just work.
Auto-advances through each phase. Space start/pause · S skip · R reset · F full screen.
About the Boxing Timer
The boxing timer alternates audible round and rest phases so you can train to the bell without watching the screen.
A boxing round timer is designed around audible transitions. Set the round length, recovery and total rounds for the session you are actually doing; competition formats vary by ruleset, level and discipline.
The twelve-round, three-minute preset is useful for one familiar format, but bag work, technical drilling, amateur bouts and MMA training may use different lengths. Follow your coach or governing rules rather than treating one web preset as universal.
Plan each phase before the first bell
| Phase | Focus |
|---|---|
| Round | One clear technical or conditioning objective |
| Rest | Recover, listen to coaching and prepare the next objective |
| Final bell | Stop the drill and cool down rather than adding an unplanned round |
Tip: Set the screen to stay awake before training.
Tip: Use shorter technical rounds when quality matters more than fatigue.
Tip: Keep the device outside the strike area and control it before gloves go on.
Make the bells unambiguous
Test audio before putting on gloves, keep the device where everyone can hear it, and use a distinct event name when several groups train nearby. For supervised sparring, the coach or official remains responsible for starting and stopping the action; the browser timer is a supporting cue.
