As in title, clean interface and easy to use. As mentioned by another reviewer, I would also prefer iOS Health interface read as a workout instead of just energy expended so that workouts can be tracked over time instead of just lost into a random days calories. Overall, though, highly recommend for basic Tabata needs and I would even consider upgrading to pro if devs are committed to maintaining/ updating app going forward.

It says u can add songs but it won’t allow me to

App works great. I like that it ties into my music that I have stored on my phone.

Hhh

Workout can be intense for someone just starting out. I loved it, it was tough at first but worth the results.

If you don’t pay, you get 4 basic free workouts. Not bad.

This is the most confusing interval timer. It’s an interval time doesn’t need to be complicated. Could not use my music either.

I use the app for beginner runner workout.

Good, but would like to use other music sources than iTunes and log the workout in the health app as an actual workout not energy.

Great!
