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 12 and works great on iPhones, iPods, and iPads.

One of the best grading apps

This app is so simple you don’t have to do anything or connect anything. You just type the number of the questions and you automatically get to see. The setting section is also really simple just clicking buttons and that’s it. The app doesn’t gives any apps and it is super convenient.

Would love to give 5 stars...but

This app is super handy. I love that I can look at the grades for number correct, number wrong, and half points. The color coding is great also for quick glances when grading papers. The ONLY issue I have is that this app drains my battery. I can start with 100%, and after 20 minutes of grading I’m down to 68%. That much drain is ridiculous. I can’t leave it running in the background either for grading papers here and there throughout the day. If I do, my phone is below 20% by the time I leave school. This is the only issue I have with the app, but the power drain is significant enough that I can not rate higher.

Good, but needs multiple saved profiles to switch between

I would love to see an option to toggle between multiple save profiles with the save number of questions. There are times where I am grading multiple assignments with different numbers of questions. I currently have to constantly manually change the number of questions. If I could go between saved profiles, it would save me a tremendous amount of time.
