Boxing Round Interval Timer

Ring Timer is a boxing round timer made for proper training: sparring, pad work, punch bag rounds, MMA, Muay Thai, kickboxing, HIIT and tabata. Set your rounds, rest and warnings once, press start and get to work. The interval timer takes its time from the clock, so the gym bell rings on the second even when your phone is locked, the screen is off or your music is playing. No ads, no account, and nothing interrupts a session.

Use it as a boxing round timer in the garage, an MMA timer for sparring nights or a HIIT and tabata gym timer for conditioning. Every built-in preset and the full timer are yours to use from day one.

Key Features

Lock-Proof Timer
Your boxing timer keeps ringing on time with the phone locked or in your pocket.
Late cues are dropped, so sounds never pile up when you unlock.

Live Countdown on the Lock Screen
See the round, the phase and the seconds left without unlocking.
On iPhone it runs in the Dynamic Island; on Android as a live notification.

Presets for Every Combat Sport
Amateur and pro boxing, women's pro, MMA, MMA title, Muay Thai and kickboxing.
Plus BJJ rolls, heavy bag, shadow boxing, tabata, HIIT and EMOM, ready in one tap.

Real Gym Bell and Round Warnings
Single or triple bell, 10-second clapper, buzzer, gong and whistle.
Stack warnings before the round ends and give the final round its own bell.

Custom Round Timer
Set round length, rest, prepare and cool-down, from 1 to 99 rounds or unlimited.
Save up to three custom presets for your own boxing and MMA sessions.

Round Builder (Pro)
Give every round its own length and rest, like a proper fight camp session.
Build pyramid rounds, sprint rounds or a championship final round.

Coach Mode (Pro)
A spoken cornerman calls out punch combos 1 to 6 while you work the bag.
Choose orthodox or southpaw, three levels, defence cues and sprint bursts, fully offline.

Plays Nicely With Your Music
Your playlist keeps playing and only dips while a bell or callout sounds.
Volume boost lets the bell cut through a noisy gym.

Glove-Friendly Controls
Tap anywhere to pause, lock the controls, and the screen stays awake.
Spoken 3-2-1 countdown, vibration and a screen flash on every bell.

Gym Clock View (Pro)
Turn the phone sideways for giant digits you can read from across the ring.
Phases show by colour, ring pattern and label, so they stay clear for colour-blind athletes.

Training History and Streaks
Every session is logged with rounds and time, and your streak grows day by day.
Seven days of history are always included; Pro keeps the lot.
