I would do an in app purchase to bypass the limitations of android so I can use my USB DAC with Poweramp in my car. It's so much more polished than the other two programs. I've bought all 3 and have used Poweramp exclusively since 2011 until I put my USB DAC in. I'm using a joying headunit with a SMSL D12 DAC. I'm relegated to using UAPP which is somewhat user friendly. I hate the controls and how it all works. Hopefully this gets lift off. I'd buy it in a heart beat.
