HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (6.6 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Not that much louder

Wish it could be 20% louder

Archaic To Use

The app functionality is extremely limited. It boosts volume but every song must be manually uploaded, then added to a playlist which usher is unable to edit. To arrange order of songs, you have to delete and upload exactly in order you wish to play. You can spend hours just curating a playlist. Absurd.

Great App!

Absolutely a great app! My one request is I wish it would allow you to save settings, volume, eq, and so on from song to song. Again this is a great app though. Thank you

Nicht perfekt, aber ok

Ich bekam diese App for free, was immer eine tolle Sache ist. Leider funktioniert diese hier noch nicht perfekt, bassbosst ging garnicht, leider erkennt er keine ganzen Ordner und es gibt hier auch keine Internet Radiosender. Apple ist ja beschränkt was andere Apps angeht, also muss diese App alles erledigen. Aber denke diese wird weiter entwickelt. 3 von 5 Sterne An die Entwickler: - Ordner sollten einfügbar sein - Video abspielbar *. mp4 - Internet Radio Sendersuche + Favoriten - Cloud Service
