As you see above, when you open up the app, you will now see two tabs on top instead of three: whereas before, you had What’s On, Devices, and Get Apps, now you simply have Watch and Discover. The search bar on top has been removed, but instead it appears as a floating action button at the bottom of the screen. It is worth noting that the color scheme has also been changed to be more “material.”
Also the icon of the app got an update too. It is a small house with all the Google colors; curiously enough, however, the new Google Home app is not circular. Given the latest Pixel UI that we saw from Google, we thought Google would have streamlined all their apps.
So, that's the end of the Google Cast app, it has come a long way. Introduced as the Chromecast app, it went through its initial rebranding when its functionality was expanded. Now with the Mountain View company’s slew of Home-branded products, it makes sense that Google wants to bring all Chromecast devices under one roof.
Once the update is available for all, you will see it pop up in Google Play. If you used the Google Cast app or have a Google Home device pre-ordered, be sure to be on the lookout for it.
