Round Bell

Round Bell is a round timer that assumes you are three metres away with your hands wrapped.

Presets cover the formats people actually use -- boxing rounds, MMA rounds, Tabata and general HIIT -- so a session starts in one tap instead of a configuration session.

The timer screen is deliberately blunt. Digits fill the screen, the background carries the phase as colour -- red for work, green for rest -- and the final ten seconds change state so you know the round is closing without reading anything. The gong marks the transitions.

The interval editor builds anything the presets do not: round count, work duration, rest duration, and a warning period, saved as your own preset for next time.

A session log records what you actually completed, sparring and conditioning separately, which over a few weeks shows whether your conditioning work is keeping up with your ring time or quietly falling behind.

Settings cover the background audio behaviour and keeping the screen awake, which matters more than it sounds when your phone is across the room.

Round Bell is fully offline. No account, no purchases, no ads between rounds. Just a red screen, ten seconds left and the bell.
