Pay once. No ads. No subscription. No account. Ever. BoxBell is a boxing round timer that does one job properly. 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 10-second prep countdown before round one · Bell volume, haptics, sounds on or off · No ads. Not now, not later. BOXBELL PRO — ONE PAYMENT, US$5.99 · Custom round and rest lengths · Saved presets · Sound packs — Deep and Bright bells alongside Classic · Voice round announcements One payment. Yours forever. No subscription, no renewal, nothing to cancel. (US price; your store shows your local price.) IT DOESN'T DIE MID-ROUND Keeps running with the screen locked, in the background, with your music playing. The bell ducks your music for a moment, then hands it straight back. The bell rings even with the silent switch on. The clock is built on elapsed time, not ticks, so it can't drift or skip while your phone sleeps. WHO IT'S FOR Boxing, kickboxing, Muay Thai, MMA. Shadowboxing, heavy bag, pad work, sparring rounds. HIIT and circuit work too — any 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. 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. Built by one person who got tired of paying for a timer twice.
