App Lock is an app protector which could protect your privacy. It can lock contacts, SMS, e-mail, gallery, settings, calls or any apps by password or pattern lock.
With this app, you don't have to worry about your private information on your phone to be exposed to other people, you don't have to worry about your kids messing your phone up by changing the settings.
This app will use Accessibility API to read app names, app icons and package names of all apps including the current app you are using so that it can lock them with password.
A lot of improvements.
