Before I accidentally found your app, I spend very much time to find any app that can control pulseaudio volume from Android - I search Google Play Market, XDA Forum, Google and other searchers, and find nothing.

So, seems that your app is only one working solution for PA control in android - Reverb app, thanks for it!

But not each other user can quckly find your app, so will be good if you add your app to Google Play Market, I think that it will got many downloads and stars!

Also you can add to Play Market free version and paid version too (for example, in free version user can add only one pulseaudio server ip), in order to earn money and increase interest in the development of new versions and adding new functional.

Or at first you can start with Donate button on app homepage. I already want to donate some money for your project, to see in future new versions with improved functional.
