When Google revealed the Nexus 5 along side it they unveiled Android KitKat and it’s new Google Now launcher. For a while the launcher was exclusive to the Nexus 5 but now Google has released the homescreen replacement onto the Google Play Store for all Nexus and Google Play Edition devices!
The Nexus 5 has been the only device to have what used to be called the “Google Experience Launcher” for some time which offers the “Okay Google” voice searching right from your homescreen as well as a quick swipe to view contextual cards. The Google Now Launcher, as it’s now called, also makes the notification center and the navigation bar on some Nexus devices translucent giving the illusion of a larger screen.
To download the Google Now Launcher, head on over to Google Play on your Nexus or Google Play Edition device, or tap/click here.
