APPLOCK is one of my favorite application on android platform. With the help of this application, we can lock our all apps according to our desire. Talking about the interface, it is very easy to use and user friendly. It has two lock option either you can use pattern or password. Moreover, the size of the application is very small, so, it does not consume much internal memory space. You can also use PHOTO VAULT feature to put your private photos separate from the gallery. The installation of the application is very simple. The little disappointing thing in the application is advertisements otherwise everything is great. THANKS.
