For IOS apps, check out applevis (www.applevis.com). No matter what you need to do, Applevis probably lists several apps for doing it, with detailed comments about how accessible they are.
On Windows,
$1 is a good starting point to find all of the essential accessible software.
Right at this moment, I'm particularly enjoying

It isn't school related, but combining all of my entertainment options (YouTube/Netflix/Livestream/etc) into an application that has the same interface for all of them is quite an accessibility win for me. It's almost nice enough to tempt me to abandon my Apple TV, once they get one or two bugs straightened out.
