Appearance

System follows whatever your iPhone is set to.

Profile

A direction, not a deadline. Reassess it whenever you want.

Workout days

A reminder only. The next workout is always the next one in the rotation — train Day 1 on a Saturday and Day 2 is still next.

During a workout

Sound when rest finishes — tap one to hear it

Screen

While a workout is open, the screen stays on instead of dimming out between sets. It still turns off the moment you press the side button, and it releases as soon as you leave the workout — so it cannot quietly drain the battery in your bag.

Your data

Not set up — everything stays on this phone

Every set is written to this phone the moment you log it, so the app works the same with no signal. If cloud sync is set up, it catches up in the background once you are back on.
