Wifi Auto

(Android 4.1 or above)
Distribute an app that I made to myself. Wanted to save battery when I was not home and had wifi connection. App runs in the background. Turns off wifi when you are not connected. Trying to reconnect every 30 minutes. You can not change the settings in any way.

How to use it:
When you launch the app there is no screen but you can see the app running in the background if you go to settings> apps> running.

Note:
First run shuts down wifi. Start wifi manually after running the program once.

This app does not shut down "Scanning always available". You have to turn it off in settings > wifi > advanced.
