Strong password or cool lock screen? Of course NOT. The best protector would let prier not to be aware of any protection is applied for your apps. App Lock II is one such protector.
★ How it works?
When launching a protected app, it will throw a fake crash error which may mislead guest user into thinking that your app has a glitch or something. So it can stop guest from using your protected app in a natural manner.
But owner can clear it through several secret ways. It also provides a password protector with a secret input method.
★ How to launch it?
This is a widget version of App Locker II, it will not show any app icon in the app launcher board, so guest user hard to find it.
For owner, please long press the empty area of Home screen, and select the 'Z_AL II' widget from the 'Widget' menu. Then you can click the widget icon to open the App Locker and manage your protected apps. You would better remove the icon from Home screen after you finish the management.
