FAQ
Is this good for HIIT workouts?

Yes, that's exactly what it's built for — set your work/rest split and round count and go.

Can I pause mid-round?

Currently there's no pause mid-round; press Reset and Start again if you need to stop.

Does it beep at every transition?

Yes, every switch between work and rest triggers a short beep so you don't have to watch the screen.
