The app can be launched by tapping at the right or left corner of the screen. The nine categories which the app makes are: Play, Talk, Work, Seek, Relax, Setup, Live, Read and Lost. Tap anyone of them to see what apps have been placed in which category. If you’re not satisfied with the manual categorization, it can be done manually. Just long press the app you want to move and drag it to the desired category, and all the apps will be in alphabetical order.
There’s an option to change the color of the launcher icons and the text in order to make the app go with the theme of your android device. Androites can get ReLaunch-Launcher free from the Google Play store. There's a video on YouTube as well for the androites.
