Build custom interval timers for HIIT, Tabata, boxing, MMA, gym circuits and any workout that needs timed rounds, rests or cues.

Interval Timer: HIIT & Gym helps you create flexible workout timers that match the way you train. Use it for HIIT workouts, Tabata sessions, boxing rounds, MMA training, Muay Thai, kickboxing, circuit training, strength intervals, warmups, cooldowns, stretching and recovery.

Unlike basic interval timers, this app lets you build your own workout from simple reusable blocks. Add work periods, rest periods, repeated groups, nested rounds, manual counting blocks and custom sound cues to create the exact timer your session needs.
