Everything a workout needs

Five numbers and go

Work, sets, rest, rounds, round break. Set them once and hit Start. Save any workout as a template and it is one tap away next time.

Readable across the room

Big, bold numerals, a color for every interval type and a haptic tap on each change. A voice coach calls the switches out loud, so you never have to look down mid set.

Pause, skip, rewind

Pause and pick up exactly where you left off, or jump an interval forward or back when a set needs cutting short. No restarting the workout.

Stay consistent

A weekly goal, and a streak worth protecting.

Pick how many workouts a week keep your streak alive. The home screen shows where you stand before you even start, and the Stats tab collects the ring, a chart of your recent weeks, your totals and your full history. An optional daily reminder nudges you at a time you choose, and skips the days you already trained.
