K9 also has a time restriction feature, it is great, cuts me off at 12 every night. Just "IMO", block youtube whatever you do. SafeEyes is great but I had same issues. I have someone else administrating both filters so I can not change settings. In K9, I set the email address up as my friend's so I can not do "forgot password..."
