You can even impress your pals by recreating the face recognition scene from Mission Impossible Ghost Protocal. The app does all of the heavy lifting. All you need to do is choose a picture from your camera roll, gallery or social networking profile, or use the camera on your phone to take a preview without saving the shot. Faces are quickly identified by name on the screen with a degree of confidence. You can set the app to automatically log into Facebook and you can even find out how many of your Facebook friends have public images. In case you are worried, the app saves not one iota of personal information.
Who on Earth is 99 cents from the Windows Marketplace although there is a free trial period supported by ads.
