Always room for more!
Desmos, in its current state, is the most amazing, intuitive, and capable graphing app I’ve ever used. As a math major, I have a deep appreciation for Desmos. One thing I’ve always wanted to see is the ability to use inverse of any arbitrary function. Like if I defined some f(x), I’d like to define g(x) as being f^-1(x). Also, you have line fitting capability but eventually I’d like to see curve fitting and sinusoidal curve fitting. The last thing I’d like to see in the future is an “advanced mode” of sorts that includes the ability to graph functions of two variables like planes or parametric curves/surfaces on a 3-D plane or even the ability to graph complex functions. These are just the thoughts and suggestions of an ambitious mathematician.

Poor and unreliable
I used to think that Demos was a wonderful graphing tool. However, as I get into higher math, Desmos has become worse and worse, and I have seen a number of glaring issues that don’t follow any logic, leading to random solutions. For example, Desmos has a random obsession with not graphing statements due to parentheses which are not clearly wrong or missing even though they are leveled as such.

Great, but could use one small addition.
The app works very well and I am quite satisfied with it, but if it could include an open spot where a function is undefined, that would be nice. The graph will show that it exists, but if you hover over the value, it shows that it does not exist.
Explore math with Desmos! Plot functions, create tables, add sliders, animate your graphs, and more -- all for free. At Desmos, we imagine a world of universal math literacy and envision a world where math is accessible and enjoyable for all students. We believe the key is learning by doing. To achieve this vision, we’ve started by building the next generation of the graphing calculator. Using our powerful and blazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. Sliders make it a breeze to demonstrate function transformations. It's intuitive, beautiful math. And best of all: it's completely free. Features: Graphing: Plot polar, cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time - and you don’t even need to enter expressions in y= form! Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph. Try typing y=mx+b and adding sliders to get started. Tables: Input and plot data, or create an input-output table for any function. Statistics: Find best-fit lines, parabolas, and more. Calculus: Graph derivatives (d/dx) and explore key concepts by building secant and tangent line sliders. Graph Maclaurin Series (okay, all kinds of Taylor Series, but that guy gets no love...) Evaluate a definite integral (int) in an instant, or plot an integral with varying bounds. Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window. Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger. Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. It can handle square roots, logs, absolute value, and more. Inequalities: Plot cartesian and polar inequalities. Offline: No internet access required.
