You should be moving,
not watching a clock.

Build a workout

Add an exercise, give it a length, add a rest, give that one a length too, and keep going for as long as the session needs. Every step is named, so the screen tells you what you are doing rather than only how long is left.

Pick from the built-in catalogue or type your own name. A name you type is kept, and it is one tap away the next time.

Or set rounds

When the movement does not need naming — a circuit, a bag, a sprint — say how many rounds, how long you work and how long you rest, and the whole session is built for you. It opens at ten rounds of ninety seconds on and thirty off, and every one of those three numbers is yours to change.

There is no rest tacked on after the final round, because nobody wants one there.

Save it and use it again

A session you built becomes a template with its times already in it. Edit it, duplicate it when you want to change one thing without spoiling the original, archive the ones you are not using this month, delete the ones you are done with.

Swipe a card to reach any of that. The archive folds away on its own.

The warning is heard, not seen

In the closing seconds of a step the screen turns red and the app beeps once a second. You choose whether that window is the last three, five or ten seconds — and you choose it separately for exercises and for rests, because the two are not the same problem. Out of the box it is five seconds before work ends and three before a rest does.

It works where you put the phone

Portrait and landscape are the same layout laid out two ways, so a phone propped against a water bottle reads as well as one in your hand. On an iPad the whole thing simply grows.

The screen does not dim mid-set, and the sound plays even with the ringer switched off.

It knows what is next

The name of the coming step is on screen while the current one runs, so a rest is never a blank pause you have to guess your way out of. Pause, skip forward, go back a step.

Time is counted against the clock rather than by adding up ticks, which is why a session is still right after the app has been in your pocket.

Seven groups, and an eighth that is yours

The catalogue is sorted the way a session is planned, not alphabetically: you go looking for something to warm up with, or something for legs. The exercises you named yourself sit in a group of their own and behave exactly like the built-in ones.

Your three devices agree

Workouts, the exercises you named yourself and your name travel between your iPhone, your iPad and your Mac through your own iCloud. There is no account to make and no server of ours in the middle — the copy that travels sits in your Apple Account, under Apple's keys, and we cannot read it.

It speaks your language

Rounds follows whatever your device is set to, so there is no language switch to find.

It asks your name once, at the start, and uses it. On iPhone and iPad the free version also asks whether ads may be personalised; buy the ad-free unlock and that question never comes.
