Device tracking software is software installed in an electronic device that is capable of reporting the device's location remotely. Depending upon the software and the device on which it is installed, the software may obtain the location of the device by means of GPS, WiFi-location, IP address, or accelerometer logs, and it may report the address by means of e-mail, SMS, or other means.
Some device tracking software is sold as part of a subscription to a staffed service that will assist the device's owner to update police officers with the device's location.
