Corner: Boxing Round Timer

Read every round across the gym with the full-screen Gym Clock, and feel the bell on your wrist on Apple Watch. Free boxing timer inside — no ads, no subscription.

CORNER — THE BOXING ROUND TIMER YOU CAN READ ACROSS THE GYM

Corner is a round and interval timer built for combat sports and high-intensity training. Big, bold, readable — from the ring, the bag, or the far side of the gym.

FREE — A COMPLETE BOXING TIMER Start training in seconds with the classic boxing preset: 3:00 rounds, 1:00 rest, with prep, a 10-second warning, and the bell. Full-bleed phase colors — green to fight, amber for the last ten, red to rest — so you always know where you are at a glance. Works in portrait and landscape, keeps the screen awake, and sounds the bell even on silent or with the phone locked in your pocket.
