Awesome for long run intervals

I’ve been using Intervals Pro for 3 years and it’s been fantastic. I love that I can set different training intervals, depending on my training schedule.

Honestly… years in and I still love this app. Gets used daily.

Everyone should own this app… it is one of the best apps out there. I fee like the applications of it’s functionality our vast. Anyone who buys this app and takes the time to put it to use will decide it’s amazing. From working out to kitchen timers to idk…. Endless possibilities where this app can be helpful.

Mega Great

Awesome app Love it!!!

Monteization

The free aspects of the app appear balanced, but why pigeon hole people a annual or monthly subscription? A one off lifetime payment would boost this to a 5 star for me.

I hate this app

I use this app for my coaching job and half the time the program won’t save even tho I click done. The workout is not there so I have to take another 30-45 minutes to program the workout into the app. Not to mention it has recently started glitching to where it changes the timing on the timer even though I select a different amount of time.
