terribile
hate this cant do anything because of it
This is an invasion of my privacy! I don't understand why it is necessary. If a teacher can't control their class enough to stop them from playing games, then that teacher should fired!
I just reported this add-on to Google so it will hopefully be removed from the Chrome web store.
It sucks...
We use this and it is great. To all of those who put bad reviews it is because they are students using their school issued computers and did not read their responsible use agreements. Use your school computer to learn, it is not a toy.
I can't even use dr.doob websites wish I could give it a 0
joo
this is undeniably malware - it's not able to be uninstalled, limits the functions of your browser, allows others to see what's on your screen... heck, it even hides the icon on the chrome extensions bar.
This the best app ever. A lot of people complain about it, but I have no clue why. I am glad the school I go to downloaded this wonderful app. Now that it won't let me go on my favorite apps, it means I can focus more. I brought my grades up by 50% just by using this app. Please rate this five stars and stop hating on it. Even if I didn't have to, I would most likely download this either way. It's my favorite app in all of the appstore! :) (I am not a teacher)
