One of the most publicized and probably the most gimmicky feature in Ice Cream Sandwich/Galaxy Nexus is the Face Unlock feature. Unlocking your phone by just bringing your face in front of your phone is definitely cool and geeky on paper, but is quite a bit impractical in real life.
Ever since Google’s announcement, quite a few apps have popped up in the Android Market that brings the Face Unlock feature to Android handset running Gingerbread.
FaceLock for Apps takes Face Unlock to the next level. As its name of the app suggests, the app protects all the other apps installed on your phone and will only open them when it detects the face of the user. The free version of the app allows users to protect only one app, apart from the pre-defined ones. The app also locks down the Settings menu of your phone so that no one can uninstall the app.

FaceLock for apps works with Android 2.3 and Android 4.0 devices, and the developer is also working hard on adding support for handsets running Android 2.2. Keep in mind that if your Android phone has a poor front-facing camera, then the app will struggle to work properly. In addition, Face Unlock is ultimately just a gimmick, and does not offer foolproof security.
A free as well as a paid version of FaceLock for apps is available on the Android Market. Here is the link to the free version of the app.
