Hola Screen Lock

a Screen Lock is an app that lets you turn off the screen of your Android by tapping twice on the desktop. This works as long as you have Hola Launcher installed, which is a requirement to use this app. It's important to note that Hola Screen Lock doesn't work by itself. You can't install the app and expect it to work on any Android launcher. The app ONLY works on Hola Launcher. In the app settings you can make it close all the apps that are running when you lock the screen. You can also include some apps on the exception list so they don't close like the others. Hola Screen Lock is an interesting app, which in the end helps extend the life of your Android power button.
