Apple devices and smartphones powered by Windows Phone come with built-in support for location tracking, and free apps in the Google Play store allow Android device users to find their cellphones. These apps use a data connections to report the phone's location.
The Find my iPhone app and the Windows Phone equivalent report the last-known location of the phone if current data is not available. The Plan B app for Android devices is not as sophisticated as AndroidLost. However, it can be installed on the phone remotely via the Google Play store, making it a good option for users who have already lost their phones or tablet devices.
