Let us get to the Pros and Cons.


1. It is free of cost and doesn’t contain any In-app purchase.

2. The GUI has a good look and feel.

3. You will get the hang of it in the first go. The app is easy to understand and use.


1. With the competition so high in Android market, it lacks a few features like capturing a photo when someone enters a wrong pin.

2. It contains ads but honestly it helps us earn something to keep improving the app. Moreover, we have tried to keep the ads in a way that doesn’t hamper user experience.

We are working hard to bring more features in the app and keep the cons to a minimum.

Apart from this, we have also released a Premium version of this app by the name of Advanced Chat Locker.

Currently, the additional thing premium version offer is that it is ads-free. Soon there will be advanced features introduced in this app.

This brings me to an end of the review. We would love to get the feedback of the App from you. Please let us know if you think of any useful feature that can be added to the app or issue(if any) you get while using the app in the comments section.
