It's only a little over a year old by now and even the first release was better than most of the stuff out there, but what it is today makes it better than anything I have ever used before on my phone and that includes premium apps like Spotify. At this point, I can't even think of stuff I would need anymore, but I can't wait to see what the next year brings.
Another note, the developer also created yatse, which I used over a decade ago as my remote control for kodi. Also equally as awesome as this is. He is very good at what he does, haha.
