Ratings and reviews

Despite the good looks, lacks real polish and intuitiveness. Ex, pressing the VAR let brings up a list of variables, as expected, but then pressing the back key exits the entire app. What if I pressed the VAR key by accident? That's like being forced to eat a dish one ordered by mistake - this behavior has no place anywhere in a modern GUI. It's not clear how to access any of the trig functions from the CALC menu either; it should be. This app needs help.

Very impressive, with fast rendering! The UI could be better. Suggestion: move the equals button (=) in the calculator to one corner of the screen, say bottom right, and leave the button in the same location in graphing mode, with a calculator icon instead (+-×÷). It would make switching back and forth much more intuitive. The save/retrieve interface should have its own modal overlay, the same one in both cases. That would give you the ability to tap an existing file to overwrite when saving.

The app is pretty good and nearly has everything a mathematician or student would need. But there are serious issues, for example for some reason manually inputting any trig equation without using examples caused the app to produce a constant value instead of a wave, not sure why its doing that. Oh and as a note it would be nice if they added a larger range for both T and the graphs themselves. Apart from that the app is a really fun way to visualize maths.
