      When someone tries to access your password protected application, AppCrypt will ask he or she to enter a password. If the password is wrong, system will keep a record automatically with photo, time and reason.

      As far as I know, there are no free ways to password protection individual applications. But you can use Mac's built-in Parental Control to set restriction on some apps.
