QuickHAC (or qHAC, pronounced "quack") provides you with a quick and efficient way to keep up with your grades.

By harnessing the power of Google Chrome, QuickHAC checks HAC for you automatically and notifies you whenever your grade changes. It continues to check your grades (every hour by default) as long as you have Chrome running, so you never have to check HAC again.

Furthermore, QuickHAC colors in your grades according to how good they are. A 100 is always white, while lesser grades become either yellow, orange, or red, depending on how bad they are. This makes it easy to spot bad grades that need improvement.

An adjustable setting controls which grades are which color, depending on how much you care about your grades or how colorful you want them to be.

And best of all, QuickHAC is free, just like all of our previous apps.
