I am the founder of https://appstorerankings.net , a startup focused on ASO (App Store Optimization), so I'd looked up your app's keywords -- you're using "personal,live,movie,cloud,stream,air,share,remote" . That's only 49 characters out of 100 you could be using (or you've got duplicates with the title).
You should add some new keywords to your app, here are some suggestions - "server,vlc,player,audio,airplay,wmv,mkv,avi,nmp4" in order to get more downloads (These were automatically generated based on your current keywords). A lot of your competitors use file formats as keywords, so it's probably a good idea!
Wouldn't it be cool if you could load up a URL and get transcoded audio and video of your media library for whatever browser you happen to be using?
I'll take a look and see if the web server in Tonido works there.
Edit: Looks like there's no actual transcoding option on the web interface. When I attempt to play one of my MKV files, I just get an error.
There's:
Tonido
Tonido for AppliedMicro
Tonido for Freecom
We recommend quad core cpu if you want to see 1080p movies for Tonido server.
On the other hand, I still hoard lots of Gb of mp3 files. No change there, but I can't use Spotify in my country.
