GradekeeperCost: Computer software is free, app (iOS) is $4.99
Enter assignments and scores and let Gradekeeper do the rest. Gradekeeper computes grades, does seating charts, prints reports, and sends email progress reports.
Pros: Simple to use, great for emailing reports. Very easy to manipulate data quickly and tailor the layout to your needs. Can work on your computer or on your iPad.
Cons: You have to export information from one to the other; does not sync with cloud services like Dropbox. This software/app is useful, but not beautiful. It is like excel, but tailored to the classroom.
