This is a really good app, and I also purchased the premium version. However, I have one problem with the alarm sound. I tested the alarm system, and when I unlocked the screen using the wrong password, the alarm appeared, but it didn’t turn off even after I unlocked the phone correctly. Could you please help me fix this issue?

It needs a setting where it can automatically turn on the data if they were off, when someone is trying to unlock your phone, so that it can be able to email the picture.

Thanks for your review, Albert! I understand how useful that feature would be, but unfortunately, Android doesn't allow apps to turn on data or other system services. If there's anything else on your mind, feel free to let me know! Best regards, Jakob

This app is amazing! My phone was stolen and I was beside myself over it. Then I remembered I had installed this app and checked my email. Not only did it send me a picture of who was trying to unlock it, it also sent me the address! I got my phone back. Thank you Crook Catcher developers!!!
