About this app

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.

Awesome, both on app and website. Very clean interface with no clutter and no ads. All the calculator functions are neatly foldered. Also, it's convenient to save graphs with Google account. The calculator is quite powerful and is able to carry out select calculations that Wolfram Alpha has trouble doing, like definite integrals. Also grapher is very precise; if you zoom in enough you can get more than 12 decimal points. Overall a great app and has helped me in high school, college and beyond :)

This app is very useful, and it's uses are rather decently good. However, making points follow an intersection of lines is a pain in the bust, especially when the point moves in an odd path. The slider function is easy to use, but it is lacking on the timing side. It is hard to make the points symmetrically move at the same time, resulting in some annoyances. Also, it's sound mechanics are really janky. When doing √x!, and listing to it, it creates a loud pop sound. Fix those, and I will put 5★.

This app is really handy: it's powerful enough to use for basically any math class requiring graphing functions, and a lot of fun to play around with! There are some frustrating design oversights though. The most glaring to me being that you can't (or at least I can't) scroll longer functions to edit them, and it's basically impossible to tap the edge of it to bring it into view without deleting the whole thing. Besides little annoyances like that, it's great; I hope development continues!
