BoxBell: Boxing Round Timer

A boxing round timer that does one job properly. Pay once. No ads. No subscription. No account. Ever.

Set three numbers — rounds, round length, rest length — hit START, and train. The countdown fills the screen so you can read it from across the gym: green for work, red for rest. A real boxing bell rings every round in and every round out, and a wooden clacker warns you at the last 10 seconds.

FREE, FOREVER
• Classic 3:00 rounds with 1:00 rest, any number of rounds
• The full-screen countdown, the real bell, the 10-second warning

A ROUND TIMER THAT DOESN'T DIE MID-ROUND
The number one complaint about every other boxing timer is that it stops when the screen does. BoxBell keeps running with the screen locked, in the background, with your music playing — an ongoing "Round 3 of 12" notification while a workout is live, and the bell ducks your music for a moment before handing it straight back. The clock is built on elapsed time rather than ticks, so it can't drift or skip while your phone sleeps.

WHO IT'S FOR
Boxing, kickboxing, Muay Thai and MMA — shadowboxing, heavy bag rounds, pad work, sparring. It works as a plain interval timer too: HIIT, circuits, conditioning, any work-and-rest interval that needs a bell and a number you can read from the floor.

WHAT IT DOESN'T DO
No workout logging. No coaching content. No social feed. No account, no sign-up, no email. No ads, and no ad identifiers in the app at all — the advertising ID permission is stripped out of the build. It sends crash reports and basic usage counts so I can fix what breaks. That's the whole list, and it's in the privacy policy.

WHY PAY ONCE
Boxing timers and interval timers are where subscriptions went to hide. A round timer is not a service — it's three numbers and a bell. Pay US$5.99 once, or use the classic 3:00/1:00 boxing timer free forever, with no ads either way.

Built by one person who got tired of paying for a timer twice.
