AppLock is a security application which can be used to lock application and other Setting options like incoming calls, Data and other things.
AppLock need many permission to perform it's task smoothly.
AppLock runs always in the background which consumes a lot of battery. Some time I found that it crashes when I entered wrong password.
Also I don't like it's user interface and looks very outdated. Navigation in this application is also not very smooth.
When, I enable Fake App Crash message.
Then application get crashed Everytime when I try to open any application.
I uninstalled AppLock from my phone but the App Crash Message occurs in my phone Everytime when I opened an App.
From my experience, I don't recommend this application to lock your applications because makes a lot of trouble while unlocking. And also, it consumes a high amount of battery as well.
