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


This app is everything a 21st century graphing calculator can be. HUGE thanks to the developer for the great contribution to education as a whole. I definitely think a "test mode" is the last thing needed to set this app to take over the ti monopoly. Maybe syncing to a teachers device via wifi and sending a report if a student exits test most? I'm so excited about the potential of this app. Thanks again!

I normally do not write reviews...

Okay seriously this is my first review ever. I am taking math in college and our professor allows us to use a phone for a calculator. This app is amazing when solving systems of linear equations and also works brilliantly for graphing. I'd pay 10 dollars easy for an app like this. 100 stars if I could, thank you for this !

Amazing! I'm addicted

I use it in almost every class I teach. Being able to save seemlessly with the online version allows me to increase the complexity of the things I can do without an Internet connection. Thanks!
