Where are you? Save battery for Android
Where are you? is an application that automatically turns unnecessary hardware radios off depending on your location. If a known wifi network is in range, it will automatically connect to it, turning off mobile data. When you leave your house, it will switch to mobile data connections. Also, if the display is off, all connections will be disabled.
Don't worry, you are not going to loose any watsapp at all! Autosync is enabled every 10 minutes to check if someone is thinking about you!
3 "Save battery" modes:
1- light (wifi/data on/off automatically)
2- moderate (screen off, connections off. Data check every 15 minutes)
3- extreme (screen off, connections off)
