If you are a fan of SAO (Sword Art Online) you will surely give this app a go. Named 'SAO Launcher', the app brings SAO-esque calling and messaging interface to your Android device! You can now show off to your friends the cool things you can do with this app!
SAO Launcher is currently heavily in development and so it's pretty limited in what you can do. You can look at your contacts list, message people via SMS, call people and open apps from a list. Other than that, it doesn't do much else. Oh, and it features anooting ads on the bottom of the main screen that cannot be removed unless you pay $2 or so.
You can give the app a go from the Play Store.
