XDA Senior Member bitstra has developed “Bubble Launcher,” a home-screen launcher that’s pretty refreshing and unique in terms of navigation and design. Though it’s very similar to a sidebar application, as it docks itself to the side of your screen, it still has much of the functionality of any other launcher.
The launcher is navigated through the action of swiping— swiping down lets you view all of your apps in a list format, and swiping outwards or towards the middle of the screen will allow you to use a bubble-like knob, which can be spun so that you can find the app of your choice. Swiping upwards shows the settings, which give you the option to set the launcher’s activation spot, toggle animations, and change the size of app icons.
This is certainly a really nice concept, especially the bubble-knob— it may not be for everyone because of the “bubbly” interface, but it’s definitely worth checking out. The app available for devices on Android 2.3 or newer. You can find the Google Play links after the break, as well as the APK file.
