A new android application is born

• KaRadio Remote Control by Vassilis Serasidis on google Play.

It is an easy and fast WiFi remote control for your KaRadio or KaRadio32 hardware.
With this android app you can select the WebRadio station you want to play, set the volume and get the station information such as Station name, Genre, Bit rate, Meta data and more.
