Good

Needs a way better tile, and the tutorial should be a bit easier to understand. Great app overall. Almost as good as geogebra.

Quite comfortable, but sometimes it doesn't draw the drawing.

The app is fantastic. I think to have found a bug though... When you exit the graph, if you have zoomed out a bunch..... When you try to recalc the same F or a new one, it still tries to calc all the points in the zoomed out graph so it tales forever....(truly, forever) to calc f(x)=x.... Because of this, I will have to reinstall the app and remember this until you fix it. I would say that you need to offer the option to reset the graph zoom. Other than that...awesome tool!

When you use (at^2,2at) to sketch a parabola, it shows the upper part only. I.e , only +ve values of t. But when you enter a -ve value of t in the calculate box, it show the value correctly... Please see what the problem is! There's no use of using parametric functions if it doesn't check -ve values...

Please make putting just a "x" easier

Good to use, but can be more user friendly e.g we can be allowed to change colours of graph because sometimes f(x), f'(x), f''(x) are not much distinguishable due to similar shade
