Editor's Review
CrookCatcher acts as a reliable anti-theft guard that snaps photos of anyone who enters the wrong lock screen code. I’ve used it to receive instant email alerts with intruder pictures and location data, while the PRO version adds video recording, fake screens and cloud backups. It stays battery-friendly and only activates on failed attempts. Ideal for security-focused users and anyone wanting extra device protection.

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!
