I'm using this app to do HIIT on a punching bag. Works great for planning out a workout and providing music for the intervals. Highly recommended.
Grgegr!!
should allow you to play music OUTSIDE of just apple music... there's other apps out there that carry music and you should allow access to those apps.

Love the ability to customize my own workouts and coordinate with specific songs. Would help if it actually showed what songs are selected, though.

This app is very useful in its various options for workouts. It's definitely worth paying for the upgrade to create your own intervals. I like the different options to be able to customize my workout and music.
