Lockwatch - Thief Catcher

Catch intruders with camera snaps and instant email alerts

Lockwatch - Thief Catcher is a focused security tool built to help you identify who is trying to peek at your data. Its core idea is straightforward: if someone enters the wrong unlock credential, the app quietly activates the front camera and captures a photo. That image, along with details of the attempt, is then sent to your email so you have a record of who tried to get in.

This approach makes Lockwatch a practical choice for anyone worried about theft, snooping, or general privacy breaches. The automatic photo capture can provide a clear look at the person handling your device, and the email alert gives you documentation you can act on later. Because the trigger is a failed unlock attempt, you do not need to constantly monitor your device to know if someone is probing your lock screen.

There are trade-offs to consider. The alert only occurs when the passcode or pattern is entered incorrectly, so it will not flag someone who never tries to unlock or who already knows your code. It also depends on the front-facing camera being unobstructed at the moment of the attempt. Still, within its defined scope, the app delivers exactly what it promises: a simple way to record and report unauthorized access attempts.

If you value a clear, single-purpose safeguard that captures a face and forwards the details to your inbox, Lockwatch fits the bill. It is not a complete security suite, and it does not claim to be. Instead, it adds a focused layer of evidence gathering that can deter casual snoops and help you identify would-be intruders when they slip up and enter the wrong password.
