App Description
A MODERN GRAPHING CALCULATOR ON THE iPHONE
1. Fast, Interactive Touch-Screen Graphing
2. Everything is where you’d expect it to be
3. Scrollable windows (no more spamming the up arrow keys)
4. Intelligent error messages
5. Convenient
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.
