8 of 25This has been the best graphing calculator i have found. It actually graphs all functions and other equations properly (most don't). It also makes finding the intercepts and max/min easy to do plus gives the slope/derivative. Also i like the equation solvers. Very nicely done app.
I like the ability to copy and paste during entry. When I did the last update I lost all my formulas. The 2D view needs finer lines and grids to match my display resolution - or a choice of line widths. When I print 2D, it is too murky and low quality unlike other similar apps that prints excellent. The 3D lines are excellent. Other than that I'd give it a 5 star.
This is my go to calculator
I strongly recommend this for graphing math equations. If I add something, please do graph partial differential equations
Excelent!
Very nice. Hope updates can allow the user to set the resolution. It may sometimes slow rendering, but occasionally one needs very high resolution.
This is a great (graphing) calculator app. It can do several different types of graphs, even implicit ones (like x^2 + y^2 = 1). The free version is also good, it's exactly like the paid version except it can't do all the graph types. It also has a built-in, full-featured calculator, which evaluates entire expressions (can't live without it!). It's not as powerful as some, but overall, it's a great app. Worth every penny.
Please keep the app the way it is and add iPhone X update.
