1. Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more—all for free.
2. 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.
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.

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.
Awesome but needs additional features
This is the best graphing app on the store however updates containing new features are scarce. I think support for more greek letters as variables would be great, as well as an option to whether, for example, π or e are treated as constants or variables. The Lambert W Function would be awesome (F⁻¹(xe^x)) and also the Riemann Zeta Function (convergence of sum of 1/n^x from n=0 to infinity). The ability to put minuses and plusses in subscript. The addition of the gamma constant ~0.577 and the omega constant which is the principle solution to 1 = xe^x.
Just what I needed
After trying all the different graphing calculator apps available here I finally ran into Desmos this week. I can’t believe it, this app is awesome for my calculus work, better than any of the paid calculators here. My only suggestion would be a floating input panel, because when using on an iPad in portrait view, the input is at the very bottom and very small.
