# Description

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.

THIS IS THE SEXIEST GRAPHING APP I HAVE SEEN! First of all it's free WITHOUT ADS, and it's so versatile! And pretty easy to use. Standing ovation for the developer(s).

I teach math, and desktop Desmos is my go-to calculator on my projection screen. It is simple, clean, and intuitive. I tell my students to use Desmos rather than buy clunky old handheld graphing calculators. I prefer the large screen and typewriter availability of computer over mobile, but when I'm on the go this is my first calculator to pull out.

Yours is really a great app because so many things and concepts which we have to imagine can be plotted by ourselves and viewed. Its really a great fun and helps me a lot while learning my engineering concepts. Here are my few suggestions which, if u include them in ur future updates will be a great help for people like me. 1)Give an option to share those graphs on Desmos which is really useful while studying in groups. Now I m actually sharing screenshots but its not that useful because its not possible vary the values on image you see😀 2) Give an option to user to name the axis. This is really helpful while plotting 'variations in signals' versus 'time'. This is only one such instant. 3) Your polar graph is nice but it will be really helpful if the user can plot values by substituting values for r(radius vector) and theta. Presently we have to convert polar form of an equation to Cartesian form to plot. So it would be great if you provide that feature. 4) Your keyboard is actually very good and intuitive but still it lacks some symbols. It wd be great if you provide following symbols- alpha, beta, gamma, lambda, theta, zeta , call on(:), etc.......This wd help while naming the parameters. However your subscript and superscript options are very useful and please don't remove them in ur future your updates. 5) Provide an option for the user to build his functions and name them with specific symbols so that whenever it is called it should be plotted on the graph. For example I use unit step function many times. So writing u(x) should plot unit step function.

The only Improvement I would suggest would be a talk-to-text... I am paralyzed and it is frustrating and tiresome to type in everything

Great app... Helps a lot in graphical analysis. But one thing can be added if possible... Greatest integer function, least integer function and fractional part function.

My old device was Redmi Note 4G with Android KitKat MIUI support. I now also not able to run any of the Apps ( old version }) in that phone

Good call on ":". We'll figure out where to put that. We actually support arccosh and arctanh, we just didn't have space on the keyboard. If you choose arctan and then add an 'h' it should work! Desmos Inc October 26, 2017

You should be able to download an old APK at https://support.desmos.com/hc/en-us/articles/218212723. Let me know if that helps! Honestly, the best graphing calculator on play store. Just a small request, please create another app which plots 3d implicit function like : f(x,y,z)= constant. Please include beta and gamma functions...

15/10 would recommend for people struggling with math. :) This is the best app-calc/noncalc-that I have on my phone. Have shown to many people. It is amazing.

Can't swipe a long expression sideways to look it properly. Have to click on it and use the arrow keys of the keyboard to do so. This is much annoying

A great graphing calculator! I'm surprised this app is free! Thank you so much for this amazing app, it helped me a lot! :)

This is the best graphing calculator I've ever found. Both the app and website have 0 ads, zero purchases, savable graphs. As soon as you're used to it you'll never need another calculator.

Helped me get good grades in my Algebra 2 class. 10/10 would graph again.

Most attractive of its kind. Unable to print/export. JPEG and/or PDF options would be nice.

Its the best app for plotting graphs and visualising various functions of different ranges and domains......

My teacher didn't appreciate me using during test... But it good

Being a Physics Professor I Recommend This App To All Students.

Excellent app but Plz add Greatest integer and Lowest integer functions also....

It's the best. It helps so much with visualisation of equations in maths. Would definitely recommend

It's wonderful. I am in class 9 but then also I knew to make my graph which are tought in 11. again : it's wonderful

Amazing app It helps a lott in removing doubt of students related to graph

Most amazing graphing app even use slider and plotting features are the best and unique once ever seen

Awesome can plot any complicated function for a long range of domain

Search for ad free non commercial graphing calculator ends here

You should add complex numbers, complex exponential, complex function, indefinite integrals, normal derivatives

Excellent graphing calculator. The UI is user-friendly and the inputting methods are great. 10/10

Why can I not use it to find the equation or graph of a polynomial line?!!!!

It would be great if it had a feature to add an image to the graph like on their website

Best graphing app however I would like to see 3D graphing too

From the moment I opened the app I was amazed how simple it was to do stuff

# What's New

- Fixed a bug that was causing the app to freeze. Thanks to everyone who let us know about that bug!

- Lists may be used as image coordinates, in which case one copy of the image is drawn for each list element.

- In order to better align with versions of Desmos apps used on high-stakes tests, solutions to single-variable equations are no longer displayed in the expressions list.

- User-defined labels can include interpolated constants.
