Great App, but please focus on functionality!

This App is EXACTLY what you need if you train, no matter what. At some point we all thought: why is it so complicated to have an app where you can program, organize and name a few chronometers? Well, no one did it properly until IntervalTimer arrived.

I used the app for a year, and I ever felt that I was pushed to go premium. Even having 5 different workouts per week, this covers everything. That being said: go for it, you won’t regret.

I would just ask the team behind this one thing, especially after the last update: thanks for making the App more colorful, but the attempt to improve the menus made things more complicated. Previously, you could see your entire workout in one sight, now you need to click every cycle to do changes.

Please give us the chance to choose between the old interface and the new one. I’m sure that your most loyal users would really appreciate. But again: great job guys!

Very configurable

I tried a few interval apps before settling on this one as the only app configurable enough to meet my needs. I mainly use it for running with high intervals of 4-10 minutes. Most other apps seem to restrict you to short intervals of up to 2 minutes for HIIT training, but you can easily do that with this as well. I love that I can set up a custom schedule that lets me plan out my running route, with different intervals for the uphill and downhill sections. Also love that it links to my music.
Ads are tolerable and fairly discreet, aside from the one you’re forced to watch when starting up. I’d happily pay £4 or £5 to remove it, but the subscription payment puts me off. I pay subscription to services that update content frequently, like video or music services. For a static app like this it should be a one off payment.

I think this app is awesome! I am a fitness instructor and personal trainer use it for my classes of the time! I have recommended it several times over the years

I love the ease at which you can create simple or complex workouts. This is great for times when you need different types and lengths of intervals.

One down side, it has started popping up with ads when you open the screen. There has always been ads at the bottom and they are ok but these are full screen and you can’t get to the timer unless you watch the add, apart from that a great app!
