- Tired of manually turning on and off Wifi on your phone? Let this app take care of that for you. This Auto Wifi On Off Switch allows you to automatically turn off Wifi after use, when the phone goes to standby, and to turn on Wifi only when you need it. It allows you to set it up so that Wifi will turn off automatically after the screen is turned off and turn on automatically when the screen is on. When Wifi is turned on, it automatically connects to the last connected wireless network, so there's no need for you to do anything. The whole process is automated after you set it. No more manual switching. Wifi is automatically on when you're ready to use it and automatically off when you're done. This app can be a battery saver for your phone or tablet. Your battery now can last longer than ever.
