What is CrookCatcher: Anti-Theft?
Ever handed your phone to someone and wondered if they tried getting past your lock screen the second you left the room? CrookCatcher: Anti-Theft is a security and anti-theft tool that catches anyone who enters the wrong unlock code. The app takes their photo, logs where they were standing, and emails you the evidence automatically.
The setup is straightforward. When someone types the wrong PIN, password, or pattern, the front camera fires and captures a photo. That image gets sent to your email along with GPS coordinates and an estimated street address of the attempt. You don't need to open the app or check logs later; the alert lands in your inbox with everything attached. If the person eventually guesses your code after failing a few times, the PRO version still captures them during those earlier attempts.
Key Features:
- The app emails you an intruder selfie along with GPS location and estimated address every time someone enters the wrong unlock code.
- PRO mode records video with sound and uses the back camera to capture surroundings during the intrusion.
- A loud alarm sounds and displays a warning message on the lock screen to scare off thieves.
- You can disguise the app icon and name so intruders won't recognize the security software running in the background.
- The app only activates on failed unlock attempts, keeping battery drain minimal during normal use.
Camera and location evidence
Each failed attempt triggers the front camera without the intruder noticing. The photo goes straight to your email with coordinates attached, so you can see who tried and where they were at the time. The PRO version adds video recording with audio and switches to the rear camera to capture what's around them. All evidence backs up to Google Drive automatically, so you keep the proof even if the phone disappears. The app also lets you fake a home screen after a wrong unlock; the intruder thinks they got in, and you collect more footage while they poke around.
Other anti-theft security apps
Where most apps stop at a photo and email alert, CrookCatcher: Anti-Theft layers in GPS location and estimated address reporting directly inside that same alert. Lockwatch sends an email with a photo and location when someone enters the wrong code, covering the same ground. Cerberus takes a broader approach with remote device management, including tracking, remote wipe, and audio recording across the whole device. CrookCatcher: Anti-Theft stays focused on the moment someone fails to unlock, documenting that attempt with photo, video, sound, and location in one automated email.
CrookCatcher: Anti-Theft handles one job well: catching the person who tried to unlock your phone without permission. It suits anyone who wants evidence of snooping or theft without monitoring the device constantly. The app won't work on phones with pop-up cameras or fingerprint-only unlocks, and Android 13 and later show a camera-in-use notification when it activates. You also need to unlock the phone once after every reboot to reactivate protection.
