Desmos Graphing Calculator 4+


    • Free



Explore math with the fast and powerful Desmos Graphing Calculator. Plot any equation, from lines and parabolas to derivatives and Fourier series. Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more—all for 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.
Accessibility: Read and edit math using a screen reader or a refreshable Braille display, and use audio trace to explore graphs and data through sound.
Offline: No internet access required.

What’s New

Version 6.14.0

* There’s a new way to create lists of polygons: when the polygon function is given several arguments and one or more of these arguments is a list of points, a list of polygons will be created.
* Fixed a bug that could prevent playing sound.

Just Super, But Could Use a Couple of Little Adjustments

I put this to some pretty specific and odd uses at work (carpentry; the explanation is lengthy and boring) and tried at least 20 different calculator apps in my search for just the right one. This one’s a keeper because 1) you can give it expressions in any form you want, which seems to me like something any graphing calculator should be able to handle and 2) it works offline, which also seems like something any calculator should do, since an app that has to ask a server to do calculations isn’t really a calculator, is it? The app is fast, the sliders nifty, and the layout streamlined. I also like how easily customizable the display settings are, but I wish that some of these settings, especially Reverse Contrast, were persistent, meaning they would still be as I’ve set them after I close and re-open the app. This, plus a few tweaks to Reverse Contrast, would effectively give the app a dark mode, which is never a bad feature for an app to have (I’m surprised they aren’t just calling it “Dark Mode” as-is). I also wish that the little box that displays the coordinates of a point on a line would stay visible until you tap again, not just until you lift your thumb up (there’s a way around this, but it’s not intuitive at all), and that it would move when you adjust a slider. Aside from these minor gripes, this app is super—heck, I’d pay for it.

Great but could use one extra feature

I’ve frequently used this app all through high school and college, and found it pretty useful save for one relatively minor flaw. When using it on an iPad Pro, I’d rather be able to use a Smart Keyboard than the in-app keyboard to type stuff in, especially since I don’t have to switch modes somehow to type letters instead of numbers. Hopefully a later version can account for this.

Wonderful for school and understanding how formulas work

This app is wonderful and a large part of why I don’t hate math and now actually understand what I’m doing. I can check my answers agents the original problem to check my solution and through messing around changing signs in an equation I am been able to visualize equations that would otherwise be as number soup to me.

I can’t wait for possible future updates it would be useful to be able to have an option to see the center points of conic figures as well as the foci. This is a great app and well made and I hope to see future improvements such as this.
