Out of all the app locks out there, you won’t find as unique as this one. This app is small in size but I’m really impressed with its work. The unique thing is that nobody can understand that there’s an app lock when someone tries to open an app. Almost all app lock will have number, pattern or password lock systems, but this app is completely different. To unlock it, you have to use volume button. When you lock on any app, you can notice that entering the app will not ask for a password from you. And the app will be shown as crashing. Your friend or relative will not be able to understand that you have locked your app. And you can easily unlock by clicking on the volume button.

You can use your up/down volume button. If you select 2, you have to tap 2 times on the volume button. If you select 3, you have to tap 3 times. As you see that I have selected 2 times on it, so that if I lock any app I have to tap 2 times on the volume button. The key is your choice.

After that, app will ask you to enter your volume key pattern . Enter/press it correctly.
