Corner: Boxing Timer

The bell runs the session so you can forget the clock. Free, no ads, no account.

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.
