Thanks to the fairly recent release of Google's Chromecast SDK, more and more apps are starting to add support for the extremely useful HDMI dongle. XBCM Remote application Yatse recently saw a Chromecast supporting update, and now Swiss based online radio 1.FM has also added support for streaming to Chromecast devices.
For those who may not be aware, 1.FM is an online radio broadcasting network that offers "a variety of internet radio channels covering various music genres, time period and styles." It's also free, which is always a plus.
The update is currently live in the Play Store, and you can find the application at the link below.
