Doesnt work

Im trying to log in with an iPhone and it doesnt work. We have been instructed that our childrens homework will be showing up here but we cant access the platform. If this is the way to do it, it is a total waste of time. It does not help me in any easy way. Please fix it and make it work for us! Thx.
