User reviews

The best!

I’ve been using it for my gym workouts and tennis practice to be as efficient as possible and it’s been wonderful!

Connection issues

I don’t seem to be able to start a workout from the point where I previously stopped or where I intend to start, say if I wanted to skip the rest period. It appears that I have to restart the workout from the beginning each time. Is there a way to resume a workout from where I left off?

great timer

Used many times a day... never a problem

Perfect for my needs

This app does exactly what I need it to do no more and no less.

Excellent

Intervals get broken after some time.

Update: i am an idiot. I recorded a screen with app notifications on and thought those extra “notifications “ were coming from the app.
