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

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.

Great App

This is my favorite graphing calculator but the one thing i think it needs is a button to save the settings that i change for future use.


Love Desmos, but terrible for iPhone
Nick Name, Esq.

I think Desmos is fantastic, and works so well on the iPad or computer. Just don’t bother using it for an iPhone. The buttons are so small that it isn’t worth your time and there is no landscape mode. Not really their fault but I would love to see a port with those features


The greatest there is

I’m a university math student and as such, I’ve had a deep appreciation for Desmos since I downloaded it in high school. The incredible amount of functionality in this app is truly what sets it apart from anything else I’ve ever used. From implicit curves to parametric equations, from multi variable integrals to combinations/permutations. As it is, Desmos registers f(x,y)=g(x,y) as an implicit curve and even r=f(θ) as a polar curve. The one thing that would make this app unstoppable would be the ambitious feat of registering complex numbers. If this is ever accomplished, I think I may die.


Trash

Every time I add any value into the x or y axis and back out, it changes to some crazy high random number. I despise whoever created this app

Congrats desmos


Very Helpful
Just a high school freshman

Incredibly useful. Pretty much what got me through my freshman year Algebra course.


Great app
aguilachris

I use this app all the time for school. Would be great if I could share the app as a pdf or png on an iPad or iPhone however.


6/5

This is the best free graphing calculator. Period.


Awesome, but some slight issues
hardluck43

Formatting can be kind of annoying to understand sometimes. Could use some more tutorials. Also, DO NOT SIGN IN!!! Signing in breaks the app! If you sign in, you can only press one button and then the app becomes unresponsive. Absolutely ruinous bug.


App doesn’t work
