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.

Added Actions. Actions provide a way to react to events in the calculator, like clicks or clock ticks, by updating variables in the expression list.
Ratings and Reviews
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.
A guy with fat thumbs
This is less a review, and more a request for a change in features.
My dilemma is this: When entering text in a given calculation bar, it is sometimes necessary to select text to make changes. On the iPhone, this is done by tapping with a finger. Then, to continue the editing process, select the end of the text to continue typing numbers (etc. ). That puts your finger dangerously close to the “X” that will delete all of your work (when all you really wanted was your cursor at the end of the line). Perhaps switching to a “swipe to delete” setup for ridding unwanted calculations would spare those around me an avalanche of dismay?
