Easy to use and stable

This app works really well for the purpose of its design. It’s basically a “Set n’ Forget” process to have your radio station up and running in virtually no time.

I have used this app with a few audio interfaces obtaining consistent results while broadcasting for several continuous hours.

The interface needs some help according to today standards.

I have tried literally most of the apps created for internet broadcasting and iziCast is actually the only one which offers reliable performance.

I just hope that the developer includes FLAC as one of the available codecs.

Developer Response ,

Hello Jorgenio,

thanks for your honest review. I know that the UI could be better, but I am more a developer than a designer ;-)
I listened to your hopes and added FLAC to the newest release. Hope you like it.
You said that you tried different audio interfaces. I would be happy if you send me a list of them to so I can add them to my list of supported devices.

works great but no with kh

took me a while to figure out the issue of not being able to connect. app works fantastic with icecast 2. i was using the new icecast server kh, and the connection gets drop every 10 to 15 seconds.

re installed icecast but with version 2 and connected right away. hope they update to support newer version of shoutcast and icecast kh since they offer more features. thanks..
