About this app

Lockwatch takes a photo of anyone who tries to unlock your phone with the wrong code. It emails you the photo along with your phone's current GPS location.

Find out if someone is snooping around on your phone, or locate the thief that has stolen it.


• Takes a silent photo of the intruder using the front camera when the wrong unlock code is entered.

• Calculates the phone's location using GPS and WiFi so you can locate it.

• Immediately emails you the photo and GPS location, before the phone is switched off.

• No need for a third-party lock screen. We use the lock screen built into Android.

• The app is very small and only runs when the wrong unlock code is entered.

Lockwatch has helped recover hundreds of lost and stolen phones, and has appeared in numerous TV and online news stories. 😊

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 minimize false alarms.


Lockwatch Premium gives you access to extra features:

• Attach several photos to the email to increase the chance of catching the thief on camera.

• Attach an audio clip to the email so you can hear what's going on around your phone.

• When anyone inserts a new SIM card into your phone, you'll get an email notification.

• When the thief turns your phone on, you'll get an email notification (i.e. when they are home).

• Removes all advertisements from within the app.

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.

I installed this, set up the email, set permissions, etc, then tested it to see if it would send an email of me trying to incorrectly unlock my phone. It didn't. But I thought maybe it needed some time to send the email. I tried a few more times, then went to bed. In the morning there were still no emails. I checked my spam folder and everything. Nothing. This app was completely useless to me.

I've been using this app since 2015. It does exactly what it says and works well for me, its gotten my phone back at least a half dozen times in that span. My only issue is it stopped taking the front camera photos a few years ago and although I've moved between 2 or 3 phones in that time this feature still does not work. Currently using a new Pixel 6a and still no front photos in my failed unlock emails. Otherwise it works great and I still get the location sent.
