The CleverLoop app uses the location feature on your phone to determine if you are inside or outside your security protected area.
The location feature on your phone uses a combination of GPS, cellular and WiFI network information. As a result, any devices without GPS capability are unable to support Geofencing.
Although you can run the CleverLoop app on an iPad/iPod or Android Tablet, those devices generally don't have GPS functionality and are not able to support Geofencing.
