WiFi Auto (open source)

Save battery power on your device thanks to WiFi Auto!

When you install this app, the WiFi radio is automatically disabled when you don't use it.

Connectivity monitoring is done in background, without draining your battery.

You can also choose to automatically enable Wi-Fi on a given location (such as your home). When you stay for some time on this location, this app will enable Wi-Fi, so that your device can connect to your Wi-Fi network. Of course, when you go away from this location, the app will turn off the Wi-Fi radio to save your battery.

In summary: you don't need to worry about enabling/disabling Wi-Fi with this app!
