Lockwatch APP

Lockwatch helps protect your phone by emailing you photo, video and location evidence when someone tries to unlock it with the wrong PIN, password or pattern.

Choose one photo, three photos, or a 20-second video clip. Lockwatch sends the evidence to your email with your phone's location, so you can see who tried to get in, when it happened, and where your phone was.

Lockwatch can also alert you when a SIM card is changed or when your phone powers on or restarts. These extra alerts can help you understand where your phone may have ended up.

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

Lockwatch uses Android's built-in lock screen and only reacts when the wrong code is entered, so it stays quiet in the background without draining your battery.

NOTES

• Lockwatch only triggers when an unlock attempt contains at least four digits, password characters or pattern dots, because Android requires a minimum unlock attempt length of four.
• If the correct code is entered within 10 seconds, the alert is cancelled, so a simple mistype will not send an email.
• This app uses the Device Administrator permission to monitor screen unlock attempts. Android shows a standard warning that Device Administrator apps may erase phone data, but Lockwatch will never wipe your phone.
