WHY MAKE ANOTHER GRAPHING CALCULATOR APP?
1. We (the creators), once relied on graphing calculators, and after installing countless, similar apps, we couldn’t find anything useable. Hence, we made our own.

2. Before launching on the App Store, we personally worked with a limited, yet sizable, number of students to continuously improve the app.
