Personally I'd love to see a Poweramp skin and for example a Poweramp Visualization (preferably Spectrum Narrow) as an "Always On Display" while music is playing.
I'm not asking for something complicated, I hope. I'm just a believer in using original "equipment" if you will - if I'm using Poweramp on my smartphone then I like an extension of Poweramp on my smartwatch.
If I purchase, for example, a Mercedes Benz then I install the Mercedes Benz App (if there is one) not only because of the quality but also because I know not only has M/B has thoroughly tested the app to perform flawlessly but they may offer features a knockoff cannot. Whatever those features may be you can only have access to them through an official M/B App.
Look at all the new features that may become available if you buy the new packs you're going to be offering. Those packs will only function with the purchase of a Poweramp License to unlock the trial version, correct? Perhaps there'd be a way to code some of the basic features into a Poweramp for Wear App.
Nothing fancy or intricate, just something to provide further access and control to the main Poweramp App itself. It could even be an incentive to purchase a pack. By paying for a pack you're getting access to a Poweramp for Wear App.
