Nice. I wonder if it prevents background activity too? If I block Whatsapp using this app, would it still fetch messages in the background?

It will still fetch messages; however, you will not be notified (since it also blocks these too).

Note: there is an Apple specific bug that has yet to be fixed which causes notifications to still be read to the user if they are wearing earbuds.
