The web version and this version are bad on iPhones

I go to school and I have to use the sight to check on my grades. The problem is when I go to check on my grades in my grade book, it will just scroll the entire page, not my grade log with my assignments and stuff. So I download the app and put in my school code and my name and everything and then it tells me " would you like to pay 5$ to use the app?" Why would we have to pay 5$ dollars if its from the school!
