I can’t begin to list all the features of this app on this review, so please go to the iTunes store to see them all. However, I can tell you what I like about GradeBook Pro. Although it's a full-featured grade book, it’s amazingly simple to use. Within a few minutes from downloading the app, I had created a class, added three “students,” created some assignments, set up weighted grades, and taken attendance. For an app this complicated, I was amazed at how simple it is to use.
