Calculate84 vs Ncalc - Graphing Calculator 84 Usage & Stats

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. HOW TO SEND FEEDBACK 1. Press the red feedback button.
