Lockwatch – Protect yourself against a lost or stolen phone

[App] Lockwatch – Thief Catcher

Lockwatch  Lockwatch emails you when someone tries to unlock your phone with the wrong code.

The email includes a stealth photo taken with the front camera and a map showing the location of your phone.

Protect yourself against a lost or stolen phone by providing police with photo evidence and a location of the thief. Find out if your partner or a work colleague is trying to unlock your phone when you are not around.


Absolutely brilliant My wife left her phone in a shop, fortunately it had this app installed. We got three high-quality mugshots of the thief and the police were able to track him down and recover the phone. Highly recommended, and the premium upgrade even more so.

Perfect I used this when my phone was stolen and was totally able to track it and help the police with the investigation. I also got 3 perfect pictures of the person who stole it.


When the wrong unlock code is entered, Lockwatch will:

Take a stealth photo of the intruder using the front camera.

Determine the location of the phone using GPS and Wi-Fi.

Immediately send the photo and a map showing the location to your email address.

It’s completely silent and invisible. No warnings are shown to the intruder.

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

It works with pattern, pin or password lock screens. Fingerprint and face unlock are not supported on all devices yet.

No battery drain because the app only runs when the wrong unlock code is entered.

You must enter a minimum of 4 digits or dots for each unlock attempt. If you need further help, please read bloketech.com/lockwatch-help/?r=ps

Lockwatch user reviews :

Overall great security feature to have on your phone and I highly recommend this to my friends and my family however there seems to be an issue. I still get an email with a location and sound clip when the incorrect pin is entered however it doesn’t capture a picture anymore the way it used to on my old phone. When I go to permissions the only options it gives me are ‘only while using the app’, ‘ask every time’ and ‘deny’. Fix this and I’ll rate 5 stars. Coloros 11 Android 11.

work too good as detailed in the app it works good just you have to do proper settings of app an it give good results an just more features can be introduced to free dev try if u can .. all around its really good… an dev cab you help to get me some software which ask password before hard reset directly form recovery mode bcz if its done the google account n all thief app get erased so its difficult to get phone back if lost . so get me rply if u can help

Very nice app.. so far so good. I hope it stay this good or better unlike many other apps I have used in the past, work so good for couple of months than start acting up. Keep it up

Working as promised I have a sugestion though. It would be useful to be able to use your app for theft prevention also. If you could you add features/options like motion and unlock alert with sending thief’s photo to e-mail, then it will really be a helpful all-in-one app. I hope you can do this and I will gladly give you a 5-star rating that you deserve.
