For anyone who'd like to be able to calculate GPA using whatever formula your school and the ones you're applying to use, can I recommend OnScreen GPA Pro? No overlap with the Grades app as far as I can see, and it could be a nice complement to it. OnScreen GPA Pro also makes it easy to see the GPA implications of different future scenarios: easy turning on and off of projected semester results.
