Keys are too small, some are unreadable. Unable to get the simplest graph drawn. I think the developer can fix this and I hope he/she does.
Looks very nice, and seems to work well, but I really need a graph to plot polar functions.
Great app, but very difficult to write a function... please little more friendly user app
wish if the buttons were bigger otherwise the app really helps in drawing funcions... thanxxx
Can not use calc keyboard. Is tiny and unreadable.
The calculator is not usable. The buttons are not big enough to fit the text. Deleted until it is fixed.
