About this app

šŸ” CrookCatcher: Your Personal Phone Security Guard
Worried about phone theft or snooping? Me too, that's why I built this app. CrookCatcher protects your phone by capturing photos whenever someone enters the wrong password, PIN, or pattern. Then, it emails you with intruder photos, GPS location, and estimated address. But CrookCatcher can do lots more!

šŸ” Catch Even After Unlock

😵 Protection Against Shutdown Attempts
CrookCatcher can block the power menu, quick settings, and notification shade to capture evidence when thieves try to turn off your phone or enable airplane mode. CrookCatcher uses the accessibility permission to detect these elements on the lock screen. (Experimental feature, may not work on all devices.)

This app used to work perfectly on my phone. After the August 2022 update it is not working properly. After 8-10 attempts I might get one picture of an intruder (set for 2 failed attempts) and sometimes no pictures at all. Defeats the whole purpose of the app. I have noticed that many negative reviews are after the update date. I wish I never updated or had kept an apk file for the older version. Some apk files won't install or work but it's not working now anyways. I have to uninstall.

This app is always sending me notification via email that someone is attempting to open my phone even when my phone is just sitting on my table. It's either taking a video or a picture even if no one is trying to access it. This started happening after I signed up for the subscription. When I was on the free version, it was not doing that. It's very disappointing. May I also add that I am not happy with how the warning message pops out. It will only show once the app shows the fake home page.

I really love this app. I've been using it for more than a year now but recently, it's working abnormally. When the phone is untouched, it automatically captures without even inputting the wrong password. I was on Facebook when it suddenly captured my face. please look into it šŸ™

Hello, this can sometimes happen that your phone is very occupied doing other things when you enter the wrong password that it only takes the pictures a few minutes later. My best, Jakob
