This release does not have a Play Store Description, so we grabbed one from version 2.1.1:

This app lets you easily send commands to a device that has Cerberus installed, helping you recover your misplaced, lost or stolen Android device.
SMS control:
- Enter the phone number or select it from the contacts
- Enter your Cerberus password
- Select the command from a drop-down list
- You can choose to send the command as a normal SMS or a "data" (binary) SMS
Web control:
- All the features you have on the web dashboard (www.cerberusapp.com) with a mobile-friendly interface
- Navigation Mode, starts Maps GPS navigation and automatically updates the destination as your device moves
- Radar Mode, to have an accurate (more than GPS) indication of how near you are to the lost/stolen device measuring the signal level of WiFi hotspot
You can also see the log of SMS/web commands sent and replies received.
SMS commands are sent from your device, so standard text messaging rates apply.
