Build your own routines. Set work seconds, rest seconds, number of rounds, and warmup time. Name each phase whatever fits your routine — "Push" and "Recover" for HIIT, "Focus" and "Break" for Pomodoro, "Hold" and "Transition" for Yoga.

Free plan includes 3 custom workouts. Pro version coming soon with unlimited custom workouts.
