Corner: Boxing Timer

About

Corner is the boxing timer your gym wall wishes it was: rounds you can read across the room, run by a real bell. Open, hit START, train. Classic 3-minute rounds with 1-minute rest are one tap away, with MMA, Muay Thai, and beginner presets beside them. THE CUE GRAMMAR FIGHTERS KNOW - Bell to start the round - Wood sticks at the final ten seconds of work - Double bell to end the round - "Seconds out" warning before the next round - Haptics mirror every cue, so a muted phone still coaches BUILT LIKE AN INSTRUMENT - Enormous numerals in gym-light colors: green for work, amber for the last ten, red for rest - Keeps counting with the screen off or your music playing - Wall-clock accurate: rounds never drift, even after a phone call - Works in your pocket, on a shelf, or propped up ringside PRIVATE BY DESIGN - No ads. No account. No tracking. - Your session history stays on your device and erases in one tap. CORNER PRO — ONE PRICE, YOURS FOR LIFE The full boxing timer is free forever. Pro adds the interval designer (pyramids, tabata, combos), sound sets and themes, and unlimited history. No subscription.
