After months of missing from the Windows Phone store, iHeartRadio is back and it's sick!!
I guess it is the norm now for Microsoft to take apps off the store and give them a whole new makeover (thinking YoutTube app). Same happened here for the iHeartRadio app which was released back in the WP7.5 days but then disappeared shortly after WP8 devices were released.
iHeartRadio is not just a custom radio app, but you can also listen to live radio from any location in the US (via your data connection), so no need for an FM transmitter.
Also, there is a sleep timer feature that helps you shut off the app after a predefined time period, well thought out.
here are a few more screenshots of the app...
You can get iHeartRadio app from the windows phone store, just bing that QR-Code and start listening.
I think iHeartRadio is a regional app, meaning it only works in the US. so don't troubleshoot this app if you are outside the US and it doesn't work
