Thought it would be great but almost died doing squats – Intensity Interval Timer Review

I did not realize that you have to keep the app open so I started the timer then put my phone in my pocket and I’m doing squat after squat thinking wow 20 seconds is a lot longer than I thought!! This is dumb. I need to be able to lock my phone and have the timer still work. Also why does it have to use data. That is also dumb. I will be looking for an alternative to this app.
