Great Timer

The best tabata/interval timer for iOS. Great design, fast and straightforward. The sounds are simple and polished without being stupid.

I'd absolutely love it if the designer were able to add a super simple, super clean, totally optional way to save a few routines as presets. I love the clean, simple interface; but I find myself frequently fiddling with the times throughout my workout, which over the course of months, begins to feel a little frustrating. Wish there was some simple, elegant way to add this without compromising the clean interface, because it would add a bunch of functionality.

Aside from this common complaint, the app is great. Five stars!

If an app can be concise, this is one of them

I've been using this app for about 4 years now, and it's still great. Intuitive layout, simplistic but functional design, and it excels at what it does. For some apps, background notifications really seem to be a downfall, but I'm never worried to lock my phone and let it run while I workout. Outside of fitness, I've used it while cooking, and for a power hour with friends (shots on the minute). Basically, it's a real versatile app ;)

What you need and nothing more

So simple and easy to use.
I was a tad confused about how to adjust the times and reps when I used it for the first time, but after that it was great.

Please make an app for apple watch! The simple interface is already perfect for it, and it would make it a lot easier to listen to music and use the timer at the same time for most of my workouts
