Google today released a mobile app for its Android Device Manager service. Available for free in the Google Play store, the app lets users manage and secure an Android tablet or phone associated with their Google account from another Android device (running Gingerbread and up).
The app gives access to all Android Device Manager features, including locating a tablet or phone on a map, resetting its lock code, and erasing it completely. Just note that your missing device must be connected to the cellular network or to Wi-Fi for it to perform the commands.
Though Google released Android Device Manager in August, the initial lack of a corresponding mobile app meant that anyone with a missing handset could lock it down only through the Android Device Manager site. With this release, however, Google now has a solution comparable to Apple's Find My iPhone app.
