With this app, you can prevent unauthorized access to these apps, so even if a person wants to uninstall them on your phone, they won't be able to do it unless they have your device administrator's permission. Choose among the multiple types of locks available, including PIN, pattern, and visual password.
In addition, you may add a photo vault and set the lock screen based on the app you are currently using.
