Koush's AllCast app does a good job of streaming media to all manner of set top boxes, and of course the Chromecast. However, it hasn't always looked awesome doing it. Well, now it does – the new update comes with a refreshed UI and adds Muzei support for good measure.
AllCast now has a much improved slide out navigation menu and tabbed browsing of media. The color scheme is nice too. Your Muzei extensions will also show up as sources for content in AllCast. I'm pretty sure there's going to be a toaster with Muzei support soon enough.
Remember, AllCast requires a $4.99 premium license if you want to make real use of it. Also worth noting we're seeing a few errors with the Muzei extensions. The updated version is live in Google Play, but as of this posting the screenshots haven't been updated. We've got a few old screens preserved for posterity below.
