Fatbelly: HIIT Interval Timer

Fatbelly is a minimalist interval timer: one big countdown, clear WORK and REST phases, and nothing else on the screen. Swipe up or down to set sets, reps, work and rest, tap play, and hear a beep and feel a haptic tap at every change, with a 3-2-1 countdown before each one. Use it for HIIT, Tabata (20/10 × 8), EMOM, boxing rounds, circuits and rest between strength sets.
