Confusing subscription model

This app and other brain pop do not have a consistent payment model. Something is free something isnt, there are several apps, sometimes subscription to full access means you cannot log into mobile app. Ridiculous. I want to pay for "all" access in one shot, but it does not seem to provide that feature. I am so frustrated that I think I might have to cancel my 10 month membership. Wish they could just make a simple table so its easy to know what you are buying.
Very annoyed customer
