Like the web interface, the new app lets you remotely track and lock down your other Android devices
Google has launched a new Android app allowing users of the Android Device Manager feature to remotely track, ring, lock down or wipe their other devices. Not to be confused with the Google Play Services feature that launched a few months ago, the ADM app duplicates the functionality of the web interface, meaning you can track or control one phone or tablet using another — provided you've first enabled this feature in the Google Settings app.
If you've not yet set up remote locate or remote wipe on your target handset, you can send a notification to it through the Android Device Manager app on the second device. (Fun fact: select the device you're using the app on and it marks its location as "in your hand.")
