For performing with an IOS device I use Anytune Pro.

I've tried a few of them from free to pay.
Spend the $$$ and buy Anytune

I use mono mp3 files i build using BIAB and Logic Pro.
Anytune allows me to build set lists.
It allows me to put part markers.
I can speed up/slow down and/or change key
I can loop a section for practicing.

There is also a Mac version i use that allows me to pass song part markers and config stuff to my ios devices (phone/pad).
You can control it via bluetooth pedal (start/stop next song/ volume up down.
Muy handy feature.
Truly, I can't remember all the features.

its worth the time to check out.
I don't know of anything that come near it.
The author is pretty responsive. Code is pretty solid for my use case
If you find something better, let me know.

I do not work, nor do I receive financial compensation from Anytune
