Apex has updated their launcher to include Kit Kat features. This update is beta and you will have to be a part of their Beta testing group to download the update. This will update the look of your launcher, but it is not the full on Google Experience Launcher experience since that is exclusive for Google. The update includes Kit Kat Wallpapers, transparent/ white notification bar, and new app drawer button. Some things like the "Ok Google" from the search bar will not work without tapping the search button first. A link to the beta group is provided below if you would like to install the update.
