About this app

Lockwatch is a clever little app that secretly takes a photo using the front camera when someone enters an incorrect unlock code on your phone. It then emails you a picture of the intruder along with their GPS location, without them knowing.

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

Lockwatch uses Android's built-in lock screen and has a small app size, running only when an incorrect unlock code is entered.

Note: You must enter at least four digits or dots for each unlock attempt to be counted. If the correct code is entered within 10 seconds, Lockwatch will not send the email to avoid false alarms.

Lockwatch Premium offers additional features, such as the ability to attach multiple photos and audio clips to the email, email notifications when a new SIM card is inserted or the phone is turned on, and removal of all advertisements from the app.

This app uses the Device Administrator permission to monitor screen unlock attempts.

I just tested it and it works! It said you have to wait 10 seconds after entering the wrong password the set number of times or it won't send the email. I think that may have been the problem with some reviewers. I got an email with a picture and GPS without 3 meters of accuracy. This is all with the free version. I highly recommend this!

Simple and does exactly what it's supposed to do. The ability to track your lost device without remembering a special word or which one of your contacts you're supposed to send the special word from. Everything you need is sent to you in the body of an email once someone has attempted to gain access to your device. A photo from the front camera when the attempt was made, map showing the location of the device at the time the screen lock was incorrectly input and a link to continue tracking.

This app is really cool and is for sure worth downloading. It does exactly what it says it's going to do. I downloaded three similar apps at the same time as Lockwatch, all of them claiming to do the same thing. After testing all four apps i quickly deleted them all except Lockwatch. Lockwatch was the best in every category, beating out the competition. I've used it for a few weeks on my Galaxy S7 Edge and I have no plans on getting rid of it. I use it all the time!! Thanks!
