Lockwatch – Thief Catcher

Lockwatch secretly takes a photo using your front camera when someone enters an incorrect unlock code on your phone. It emails you the photo along with their GPS location, without them knowing. It also alerts you when a SIM card is swapped or the phone is switched off while still locked.

The app has helped recover hundreds of lost and stolen phones, and has been featured in TV and online news stories.

Lockwatch uses Android's built-in lock screen and runs only when an incorrect unlock attempt occurs, so it won't drain your battery.

NOTES

• Lockwatch only triggers if at least four digits are entered incorrectly, as Android requires a minimum PIN or pattern length of four. If the correct code is entered within 10 seconds, the alert is cancelled, so a simple mistype won't send an email.
• This app uses the Device Administrator permission to monitor screen unlock attempts. When activating Lockwatch, Android will warn that it may "erase all the phone's data". Android shows this warning for all Device Administrator apps. Lockwatch contains no code to wipe your phone.
