Best HIIT App? - iOS User

I see there is lots of HIIT apps on the iPhone. I'm asking you fitness experts out there which one works best for you? TIA!

I often make up my own using an interval timer.

I do like the Nike Training App. Not everything is HIIIT so look and I change a few things to what I need but I like how I listen with my headphones. I don't need to watch anything.
