Desmos Graphing Calculator App

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. 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. Try typing y=mx+b and adding sliders to get started. Tables: Input and plot data, or create an input-output table for any function. Statistics: Find best-fit lines, parabolas, and more. Calculus: Graph derivatives (d/dx) and explore key concepts by building secant and tangent line sliders. Graph Maclaurin Series (okay, all kinds of Taylor Series, but that guy gets no love...) Evaluate a definite integral (int) in an instant, or plot an integral with varying bounds. 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. Visit to learn more and to see the free online version of our calculator.

  • Wonderful 5/5

    By Ray.f14
    This is a wonderful application
  • It's great! 5/5

    By Mathematic lover
    It's really a great app for mathematics but I think it would be better by some sounds and music like keyboard'll make it more exciting. Other than that it's amazing😏😉
  • Amazing 5/5

    By Marcus071903
    This is better than the calculators for our school, it is so well made and I'm extremely surprised it is free! Thank you for this great app!

  • Better than 100 dollar graphing calculator, and it's free! 5/5

    By I love minecraft more than you
    This app is so much more user friendly than any other graphing calculator out there. It's got an amazing dev team that will help you with any problem free of charge. So many features, so elegant. Couldn't possible ask for more. Thank you Desmos team!
  • Awesome! 5/5

    By NGThomas
    I love Desmos. Look no further. This is probably the best graphing app available.
  • Easy to use and powerful 5/5

    By Jshedjxjbsjdjvdjwjsjs
    Very nice calc
  • Life saver 5/5

    By Ricopitbulls
    Amazing app and I'm using only a couple of the functions for homework.
  • 3D?? 5/5

    By Ezzyervxpi
    Love love this app, I will PAY AT LEAST $5 if this could graph in 3 Dimensions. It's the only feature missing, then this app would be untouchable by any that compare and definitely would be worth purchasing if it were to cost something with the feature
  • Amazing app 5/5

    By Andithevar
    This app is one of best free apps (really free w/o ads!). I'd say it is an essential app for anyone interested in mathematics. Thanks a lot to the people behind creating this awesome app.

    By Eagle360:)
    I need a graphing calculator for my algebra 2 and I left mine at school and my homework was due the next day. This blew my expectations and even had inequalitys on it which my normal calculators doesn't. 5 out of 5
  • Desmos is Amazing 5/5

    By nlaughton
    Nice work Eli! This thing is awesome. I love all the improvements you're continued to make. Can't wait for you guys to come out with a scientific calculator part so I can put my TI-84 away for good! I have all my students use you! Keep up the great work!

    By AsianGamerrr
    This is the most amazingly free graphing calculator that I have ever downloaded. It has all these options but I can't graph fully horizontal lines
  • This app is a gem 5/5

    By ThePaulMc
    I was reading through a book about Riemann called Prime Obsession and wanted to graph alongside with the author's examples. Fortunately, I came came across this app. It is perfect, but what really blew me away was the simplicity and power of the app. Spend some time with included examples to see what I'm talking about. I love stumbling across well designed apps like this one.
  • Fantastic and powerful and FUN graph calculator 5/5

    By Axiom Crux
    I make synthesizers, and this is heavily responsible for some of my current ideas, I can check out waveforms and harmonics that will result from certain dsp techniques just playing with the functions and sliders. It's so rad that you can animate the sliders at different rates. Really this is the coolest math app ever, by far.
  • Love it 5/5

    By thes7274473
    Has a wide variety of applications and uses.
  • Great graphing calculator app! 5/5

    By I like π.
    I rarely write 5-star reviews, but this is worth it. It's user-friendly and I rarely experience glitches when using it. It's good for elementary students, secondary students, university students, and others who use algebra, trigonometry, etc. It works well for computations and graphing. Personally, I like it more than my TI-84 CE graphing calculator because it's easier to enter information and change the "viewing window" to answer specific questions. I think that this app's developer(s) are missing a valuable financial opportunity by making it free.
  • What a blessing 5/5

    We used the website in math class but when I came home I decided to try the app, it's just as amazing as the website.
  • Great for Finite Mathmatics 5/5

    By tbreedi2
    I downloaded this app to use for my finite mathematics class. I originally used it via a website through the computer but wanted something a little more hands-on. This app is great for creating clear graphs and diagrams and helped make my semester a success.
  • Why I'm still alive 5/5

    By Starfyre26
    My math teacher would've killed me if I didn't finish an assignment but I needed a graphing calculator. Thank you for saving my life desmos!!!
  • Impeccable 5/5

    By G.ra.ha.m L.op.ez
    The best calculating/graphing app out there. Trying to solve a system of equations? Desmos has your back.
  • Love Desmos 5/5

    By e^(i*pi)+1=0
    I use this for teaching- great for impromptu as well as pre-planned activities.

  • 👌🏿👌🏿 5/5

    By Purple pasta
    No criticism it's actually perfect
  • Tis Amazing! 5/5

    By Some person with a Iphone 5
    It works perfectly for what I need it for and it's free, if you need to graph things quickly this is great! Not the best interface for seeing the graph but this is very minor. Great app, I'll be using it often.
  • Best Grapher 5/5

    By A Lucid Thought
    I use Desmos instead of my TI-84 plus CE I my calculus class. I save all my functions from class and revisit them at home.
  • Amazing 5/5

    The app was easy to use and saves me from doing work
  • Best graphing app ever 5/5

    By Thesah123
    This app does almost everything, and I'm surprised that it's free. It's a perfect replacement for a graphing calculator, and I can't really think of anything that this app needs to fix. Perhaps in the future this app can graph in 3-D?
  • Perfect 5/5

    By Minat0thelim3t
    I was trying so many different "graphing calculator apps" and none of them solved my problem I had without having to pay (because I have no money to give) and I came across this and it did the problem no cost included! Thank you
  • Amazing app. Would definitely recommend 5/5

    By User111121
    With this app you can create tables and beautiful graphs. Very easy to use, fast, and a pleasure to work with. I have not found any bugs yet, and I've used this app extensively, which is great.
  • Really confusing 1/5

    By Gavin Gajraj
    I hate this app
  • Best 2D plot app ever 5/5

    By SergioPolimante
    This app is the best. It can plot all sort of functions in 2D including: Functions with sum simbol. ( like Fourier series) Functions defined differently for different domain Etc Just try it and I really doubt that you won't be able to plot your 2D truncation. Most deeply of the unfortunate is that it does not plot 3D graphics. Please developers, use your talent to make a 3D graphic plot app. I am sure it would also be the best. Thanks for this app it is really great
  • Saved me 120 5/5

    By Sao 🤔🤔🤔🤔🤔🤔🤔🤔🤔
    Too good to be free, honestly.
  • Recommended by Math teachers 5/5

    By Seattlefrost7
    This was recommended by my math teacher, and it works great
  • To good to be Free 5/5

    By Anonymous Farming Farmer
    This app is really good besides some minor issues (X/0 doesn't equal to Infiniti etc.) It is a better than expected app to have no price at all. I was expecting some trashy regular app, but when I used this, not only did it give me the answer, it also gave me the graph form. I also like how theta was involved and many precalc ideas and theories. This app, overall is way better than I thought it would be! Good job developers!!!
  • My life has changed 5/5

    By Person struggling with math
    This app is a life saver! Math has never been easier!!!
  • math lover 5/5

    By Patrick2-7
    Love the app. I am very happy with the variety of mathematics available within the menus, and the shortcuts are even easier. My one complaint is that 1/0 is not infinity. That isn't quite accurate. Within real numbers, it works, but with linear functions, a slope of 1/0 should be undefined, (ie. x=0), but instead it doesn't graph. Anyway though, great app, and I love the open interface of the graph.
  • Beautiful 5/5

    By S_s_ss__s_______sss_
    simple, intuitive, & powerful. way easier to use than a regular graphing calculator
  • This app is beyond brilliant 5/5

    By Xiphidius
    Thank you so much, devs, for creating this gem. Utterly indispensable. I don't jest in the slightest when I say that Desmos has completely destroyed every other graphing calculator I've used. Keep up the good work!
  • Trash 1/5

    By Quickrev
    This thing is trash
  • Best graph calculator 5/5

    By 死心无心
    I tried several graph calculator. This one is best. It could draw algebraic curves of high degree. Animation is nice.
  • Ew. Math 1/5

    Dr. Weinberg uses this
  • Best graphing app, and it's free! 5/5

    By Nickelbackaroony
    I wish I wish more people knew about this app so that there was more graphs to mess around with but other than that this app is really good for making graphs and yeah
