Prey is a free anti-theft app that lets you keep track of your devices whenever stolen or missing, easily and all in one place.
Prey lets you keep track of your laptop, smartphone and tablet whenever stolen or missing -- easily and all in one place. It's lightweight, open source software that gives you full and remote control, 24/7. Install Prey on your devices, which silently waits for a remote signal to wake up and do its magic. The signal is sent either from the internet or through an SMS message (smartphones only) and allows you to gather information about the devices whereabouts, who has it, and even trigger remotely certain actions. Most importantly, you are able to Lock the device turning it into a brick, preventing unauthorized access. You can quickly find out where your computer is located, who's using it, and what he's doing on it thanks to Prey's powerful reports system. By marking your device as missing, Prey will gather all the evidence you request and send it either to your Control Panel account or directly to your mailbox, depending on the reporting method you choose.
