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.

Best Graphing & Regression calculator for iPad
I have my students use Desmos when they need a graphing calculator. I have really come to appreciate the calculator. The use of sliders is very simple but powerful. It also does implicit plots. I read earlier this fall that regression was in the works. Last week I was pleased to note that an update to Desmos included regression. At first I was not too excited about having to enter the equation, until I realized that there is not just a specific set of regression equations. I tried Gaussian model, logistic growth, hyperbolic cosines, amongst others. They all work perfectly! I actually like the enter your own regression equation idea better than a specific set of regression models. To the Desmos team, I say you guys Rock!
Normally, in the "hip" world in which we live in, "nasty" is a term used to describe something that is great. In this case though, it is not. It's a nasty app. The application involves doing many confusing things. These confusing things lead me into a life of depression and seclusion for one month and six days. After that, I realized that there is more to life than a graphing app. Currently, I'm back on the right track, thanks to some medication and self confidence. I wouldn't recommended this thing because it lead me to near-neath by means of suicide. I'm only giving it 5 stars because I am accepting the bribe of a cookie from a friend.
Desmos is awesome!
I've been using Desmos in the drop-in math help center at the college where I work for students and myself for more than a year, and the phone and tablet app also. With calculator, algebraic equation solving, intrinsic graphs, regression, it's now better than ever! The MathQuill input and rendering is fantastic, the graphs are beautiful, and most problems I get can be solved with Desmos.
The app doesn't yet copy and paste the equation input as the web app does, so you can input to other apps, but that doesn't reduce my rating.
Keep it up, guys! Desmos rocks!
