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.

Desmos Graphing Calculator app reviews

  • Frustrating 2/5

    By sjmj23ts
    The fact that if you insert a division symbol into an equation it automatically makes the denominator a blank box is ridiculous. I need to be able to place an in-line division symbol, so I don’t have to retype everything in the box.... and I seem not to be able to copy or paste things in the app for some reason
  • Best graphing calculator on the App Store 5/5

    Best graphing calculator on the App Store
  • Amazing so great 5/5

    By wackkkkm
    This app is so brilliant and perfect. So great so thankful for this app!!!
  • Excellent 5/5

    By Deathstroketheboss
    Five stars for being free and having a massive amount of features.
  • Super 5/5

    By Kukugkug
    I’ve been trying various graphing calculator apps. This is the best one I’ve found. The online tutorials are great. There is so much functionality built in that I would highly recommend reviewing the tutorials. My search for a Calc is over.
  • Best of the best 5/5

    By gooden11
  • Just what I needed 5/5

    By Rambo8649
    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.
  • Desmos is amazing 5/5

    By jehshshaoaa
    This app is so great and has been a staple for a long time, though the desktop website is better. Desmos is #1.
  • Works Great But... 4/5

    The app works great and graphs lines flawlessly but on my iPhone X the top and bottom of the display are cut off so if that could be fixed in a later update that would be great
  • It's pretty good 4/5

    By Mags_Mags
    Maybe I'm incompetent, but when you're dividing things in the app and it's in a decimal form there's no option to turn it into a fraction like on the website. It's a little irritating, but other than that it works great.
  • It wont save 3/5

    By ssageeee
    I’ll admit, demos is a great app. But when I graph a picture and press save It doesn’t actually save. When I press save and go out of the app, the next day everything that I “saved” is literally gone.
  • Easy To Use 5/5

    Fantastic utility; I’ve been using the desktop version for years, I strongly appreciate the simplicity and ease of use.
  • Great app, but missing advanced math features 4/5

    By 828335
    First of, it really makes me mad how they just made 2 black strips on top and bottom for iPhone X. Next, I’m very disappointed it offers no support for complex numbers. It is missing many other important things in advanced math, like vectors.
  • Matt teacher approved 5/5

    By at333302
    This is the only calculator I have my students use in class. Love it!! Super user friendly and does almost as much as the expensive TI calculators.
  • Amazing graphing calculator! 5/5

    By 😍🎷
    Love this graphing calculator, never have any problems with it
  • Gr8 5/5

    By Pocketgolf
    Way easier to graph on than my TI84 calculator. The shading effect is also useful.
  • Best All Time Math App 5/5

    By MartyCMath
    This is my favorite math app of all time. Love how it allows for math exploration, visualization, and discovery in a beautiful user friendly environment.
  • Amazing 5/5

    By Qsawdxh
    My graphing calculator costs $120 and died. This is free and super easy to use. It saved my butt and is perfect
  • Camelback High School 5/5

    By CamelbackHS
    Highly Recommended all Students to use it for trigonometry class!
  • Great! 5/5

    By BAdam001
    Best app for graphing and teaching others!
  • This app is great 5/5

    By Barnes-pen
    I love this app because i use this for school and it helps with graphing
  • Decent app 4/5

    By Tyler Tormey
    Decent app, really love desmos, but doesn’t have iPhone X support, only for the older resolutions.
  • Play all the time!!! 5/5

    By Hdhdhavdh
    So basically, my friend Ryan and I always play this game when we are bored. It’s really fun to just put in some wacky equations and see the outcome!!!! I love you Desmos! Marry me please (lowkey tho). ❤️
  • Play all day 5/5

    By hungry_hippos1
    My friend jace and I play all the time
  • Absolutely Phenominal 5/5

    By BossToxicNinja324
    This app has saved my grades hundreds of times over the past few years.
  • It could be nearly perfect by adding a camera 4/5

    By IndianMathGuy
    We all know typing big problems takes forever and if the app creators can add a camera to scan the problem it would save sooooo much time. Other than that the app is amazing. It automatically changes from degrees to radians which is always appreciated.
  • Amazingly practical 4/5

    By nathansvee
    Disclaimer: not an expert. Using a graphical calculator first time in my life. For all I care, I carry functionality with me in the same device I use to browse the web, text, call and communicate with others. As far as I can tell the functionality is super intuitive and seems to be working along with my exercises in the college level book I am reading. Terrific tool indeed!
  • Great app 5/5

    By NovaStorm93
    It is leagues beyond traditional calculators in schools, TI-73, TI-84, TI-83 are all nothing compared to this FREE phone app. It can make and hold simple variables, graph almost anything, and has easy to understand messages to show errors. It is the only calculator I trust to make and manage phone calls.
  • Awesome but needs additional features 5/5

    By Mutterbafoonnn
    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.
  • Please add fractions 4/5

    By VEA_5!
    This app is very helpful but it would be more if y’all could put fractions to be used
  • Garbage 1/5

    By Fatherdewitt
    I found this and felt relieved that I could find the answers to difficult graph questions but all this did was waste my time and give me nothing. It couldn’t even jot down points and the equations I wanted solve weren’t solved. Don’t download.
  • Amazing. 5/5

    By Nai Alceno
    This is an excellent app. Help you all the time and you can see the points in the graphic, really helps when you are looking how many zeros there are in the equations.
  • The best. One small suggestion/request! 5/5

    By NW420
    Everyone I know I’m the math department uses Desmos. It’s incredibly user friendly and versatile😀 I was stoked to download it on the iPad. One small request- please put in a theta key (for polar equations)!
  • Life 5/5

    By WHY ?!?!?!
    Best app to have on your starting Sophomore honors math throughout college.
  • Besides the lack of 3d and an ugly icon 5/5

    By dextml
    this is a fantastic math app, it replaces my calculator as well
  • Great app!!! 5/5

    By LukePoppy
    OMG it is the best graphing app!!!
  • Where’s the yellow? 2/5

    By lindsay6789
    I tried to make a rainbow graph but there was no yellow and therefore I couldn’t. The best solution is a color wheel selection tool so graphs can be whatever color people want them to be. I gave this 2 stars though because the domain tool is nice.
  • Great but could use one extra feature 4/5

    By A disgruntled PAP Bio student
    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.
  • Cool 4/5

    By Z Nyaninja
    This app is helpful and amazing. I just think we should be able to draw lines or connect points with a line. That would be the best. That’s all.
  • Glitching recently 2/5

    Whenever I use this app, go to another without closing this one, then come back to this one, the app is almost guaranteed to freeze. Then, when I close and reopen the app, any functions that I have graphed are gone. I'm only giving this two stars because this wasn't a problem until recently.
  • Perfection 5/5

    By Universe Dragon
    The desktop site was INSANELY useful in my calculus course, and now it’s an app. AMAZING. Definitely recommend for upper-level math classes.
  • It’s a calculator. 5/5

    By aidan1321
    It’s just a calculator
  • Amazing 5/5

    By 6373826
    I always used to use the website to help with graphs, and the app promises all of the features of the website and works beautifully!!
  • So fun and easy 5/5

    By isaiah potter
    I’m in algebra in the 8th grade and I have found that app helpful and easy- GREAT APP
  • Perfect 5/5

    By strqq
    Exactly what I needed.
  • Horrible 5/5

    By Hdthcdyi
    This is probably the worst thing I have ever used on the App Store
  • Spectacular 5/5

    By Snaavy
    This app is fantastic and does everything I wanted it to. Thank you for the simple graphing calculator!
  • Love it, but I have suggestions 5/5

    By ChrisMode
    The app is great, it’s user friendly, simple, and functional, but there some things that could be added to make it even better Phi: could you add the number ϕ for the golden ratio so you don’t have to put g=(1+√5)÷2in order to get it Could you add the ± and ≈ symbols for more “ambiguous” functions Could you add Boolean function symbols like ¬(not), &(and), ∨(or), and ⊻(xor)
  • Great 5/5

    By azzziiiii
    This app is super awesome I highly recommend it
