Boxing Timer
Time boxing workouts with configurable preparation, round duration, rest duration, and number of rounds. Use editable example presets like 2-minute or 3-minute rounds with 1-minute rests. Set a warning threshold before each round ends. Optional round-start, round-end, and session-complete sounds are available. See the current round, work or rest state, time remaining, and next phase. Start, pause, resume, reset, or skip phases. Full-screen mode with readable digits from a distance. Rest after the last round is not included unless explicitly enabled.
