Desmos Graphing Calculator

By Desmos

Open iTunes to buy and download apps.


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.


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

Tables: Input and plot data, or create an input-output table for any function

Statistics: Find best-fit lines, parabolas, and more.

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.

Customer Reviews

Great App

My 8th grade algebra teacher recomended this graphing calculator to us, and this one is by far the best graphing calculators I've ever used. It can be a little slow at times and should be more features such as a 3D option among other things as well, but overall, it's an easy app to get used to and it has helped me when it comes to understanding graphing. I especially like the premade graphs because they teach you about certain subjects in mathematics in a way you can easily understand them. I'm only in 9th grade so far, and I have already learned quite a bit of trigonometry and am just starting to learn differential and integral calculus thanks partially to this app. I give my thanks to the creators of this app and my 8th grade math teacher.

Near perfection

While I haven't tried many graphing apps, I don't see how this could be beat. Pretty easy to type in even the most complicated of functions, finds maxima, minima and intersections on the graph, and updates the graph in real time as you're typing. Only thing I would add is make it auto scroll the cursor to the right when typing in really long functions, and perhaps a way to copy and paste what you've just typed in. Otherwise just about perfect.

Single Greatest Graphing Tool

This is the single greatest graphing tool that I have ever come across. There are so many tools and thighs that you can do. For instance, you can graph the addition of functions, you can set domains, use sliders to assign values to variables in equations or points. There are also many examples to teach and show the beauty of math. The examples also familiarize you with the app. I highly recommend that anyone who enjoys math or would like to understand math more explore this app.
