Lockwatch is a discreet security utility for Android devices designed to capture unauthorized access attempts and send users critical information to help recover a lost or stolen phone. By leveraging the built-in lock screen, the app activates only when an incorrect unlock code is entered, silently capturing a photo of the intruder and emailing the image along with precise GPS data, without notifying the person holding the device. With lightweight operation and enhanced security features, Lockwatch serves as an effective safeguard against theft and unauthorized use.
