Do you need some peace, love and happiness in your classroom? If so you need Groovy Grader. Groovy Grader is an App designed to replace your “old school” paper grading calculator. Groovy Grader provides more flexibility, convenience and ease than other popular slide graders. It can be configured to work for 100's of questions and has the option to display the grade as a whole number or with one decimal place. Groovy Grader can show the number correct, the number wrong or both.

Groovy Grader was designed with usability as a top priority. Unlike other competing Apps, Groovy Grader can view 50 or more grades on the screen at once. It also allows you to turn off the auto-dimming screen. There's no touching to scroll for the most common grades, or to turn the screen back on.

Groovy Grader is optimized for iOS 10 and works great on iPhones, iPods, and iPads.

Love the half-point option

As a math teacher, I give partial credit in the form of half points. This is the only app that I have found that gives you this option in its settings. I also think it is easy to read and very quick when time is of the essence!

It certainly works

It works just like the old sliding easy graders of old. The ads don’t get in the way so I don’t mind them. My only critique is that it seems to drain my battery. To be fair, I know it USED to drain my battery. (Now I always make sure to close it, so I don’t know if any updates have fixed this problem.). 8/10 would recommend.

Love the improvements

I've been using this app for years and have always found it quick and easy. The improvement of having columns for both how many correct and how many incorrect just made me that much happier with it. Half points, too!
