Excellent app for protection and security! CrookCatcher exceeded my expectations. It is discreet, efficient and does exactly what it promises. I loved the functionality of taking photos of those who try to unlock their cell phone the wrong way. Furthermore, sending location information and a photo via email is a big plus, especially in cases where the device is lost or stolen. The app is easy to configure and works perfectly.
