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 www.desmos.com to learn more and to see the free online version of our calculator.

#### Great app very useful 3/5

By Cringy criticHowever i find that it would benefit the app and its user if we had the option for a fraction maybe just give us a / sign#### Awesome without bound 5/5

By Edan q.Words cannot express how great this app is. It’s an all-purpose calculator with endless possibilities that I find myself tinkering with way too often. Suggestions: -allow multi-input functions to use lists as input -points can use 2-element lists as input -let functions be repeated a variable number of times: f^2(x) is the same as f(f(x)) (input only needs to be an integer) Thanks for making this awesome app!#### 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, college students, and others who use algebra, trigonometry, etc. It works well for computations and graphing. Personally, I like it more than my TI-84 Plus 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.#### iPad keyboard 4/5

By KaydogzHey I have an iPad and I used this app and it is great, but when I type with my external iPad keyboard on the app, it doesn’t work. If you could make it so you could type equations with the external keyboard then this app would be 11/10#### 10/10 5/5

By LinithebeanieHonestly a life saver. It helps a lot with homework.#### Very helpful to double check answers for hw! 5/5

By Aston villa manager👍#### Needs iPhone X optimization 3/5

By CuckooluckooThis app is great but the black bars really kill it if it was optimized it’d be 5 ✭#### By far the best, 100/5 stars 5/5

By 12344567788900827738837329262Best graphing calculator period. And it’s free? I wish I could give them more stars.#### Yay 4/5

By 😜🤗😅I can finally check my hw questions easier#### Horrible App 1/5

By Sherman LiangI don't have a phone so I can't use it. HORRIBLE APP.#### One suggestion 5/5

By Heli 3You guys should really add a camera feature to scan these problems!#### Trig functions don’t work 1/5

By mdacrim97Pretty much says it all. It’s annoying finding out the hard way since this app got me poor grades on physics quizzes#### Please make an iPhone X version! 5/5

By Boomtrack13This app needs to fill my iPhone’s screen!#### Amazing Awesome 5/5

By jaycepeterson23I like Hummus and Desmos ya know what I mean#### Fix the sim, cos, and tan buttons. 5/5

By PayddnThis is probably one of my most favorite apps in the store with an easy to use graphing calculator that graphs the function as you place it in. Two suggestions to improve this app though are to make it so that as you are filling out a table, the calculator will automatically provide an equation that fits the data. Also, I have noticed that there are some inaccuracies when it is calculating with sine, cosine, and tangent, so you will need to fix that. Other than that, this is an awesome app that everyone should have. Keep up the good work! 👍🏻#### I wish 4/5

By geoffせんぱいI love how you can enter complex problems, but i just wish there was a way it could show your work so we could actually understand whats happening to the equation. Overall though, a great app#### Doesn't load 2/5

By Bender5960!Doesn't load properly but works great when it does#### Amazing 5/5

By HackmodfordI don’t know how math students survive without this thing. It makes all of my college math classes manageable.#### Amazing 5/5

By jendkngfid djI had algebra one homework and I didn’t have a graphing calculator. This saved me#### Excellent 5/5

By Nickname737377Excellent graphing tool.#### Great app 4/5

By TlhuxI think this app is really helpful. The only problem is that you can not do fractions. A lot of problems I have include fractions and I can't do them in the app and it is a little frustrating. Other than that this app is great.#### Love this 5/5

By Gggf5It's really easy to use 😁#### Reliable app 5/5

By tacoguy77It just a works fine!#### It's so silky smooth 5/5

By Mj312444Works great#### Great 5/5

By pizza lovathis does exactly what is said it would do, love it for math homework#### Great app! 5/5

By jennyw1Awesome graphing calculator. Sliders are the best!!#### Epic 4/5

By Moorgan HartJust wish they had an independent calculator so I could use it on tests. All other calculators pale in comparison. I use this app for a great variety of things far beyond just graphing or and general math. I've designed math lessons in it, and even done stuff like built up maps with formulas to calculate distance for theoretical navigation. The only problem is there is no autosave feature nor any remembering of the last state so when it crashes (which it does irregularly) or you leave it looking at other apps or not using phone for too long or accidentally close it all work that isnt manually saved is lost forever. I've lost countless hours of hard work this way.#### bad 1/5

By aT_Alphabad#### This app doesn't work 1/5

By MarinarieThis app is terrible#### Cool addition... 5/5

By Person #4792I love how you can make awesome pictures with functions, I just wish there was a screenshot mode so you can take a screenshot without the menu buttons.#### I LOVE DESMOS 5/5

By Trey boingI LOVE THIS APP BECAUSE I LOVE MR BROWN😫😍🤡#### absolutely perfect 5/5

By Jdaher860It is very logically designed and easy to learn. Got comfortable with it in 5 minutes. Performance is great so far.#### احلي مسا ابلبل 5/5

By Bassel_Ezzتحية لبولس الصاروخ في الرياضيات#### Amazing app!!!!? 5/5

By -_ anonymous _-This app has truly helped me pass all my math classes. It has helped me understand what in the world I was supposed to do when my teacher said, " please put this parabola in vertex form." I can't thank this app enough!!!!#### Amazing 5/5

By snchzlsI wish this had existed when I was a kid.#### Must have for students from high schools to master degrees! 5/5

By thecapnamericaIf only I had this app when I was in high school, graphing opportunities blew my imagination, you absolutely will enjoy studying math with help of this app!#### Fantastic App! 4/5

By Griffin the Math NerdI love it! So useful and it's a lot of fun to play around with. I love that you guys added integration (I stopped using it for a while and then came back). Next you should add vectors and matrices, as these will be extremely useful in a linear Algebra class with these functions and uses.#### Great App ⭐️⭐️⭐️⭐️⭐️ 5/5

By niners rule 1I love this app. It's not only my choice as a graphing calculator but all of my high school math teachers choice for a graphing calculator as well. Fantastic job.#### Stellar App 5/5

By not secureDaily, I get to use this app at work and for school; it never crashes or has a hard time with formulas. To Madminer: the app does have tables- click on the big plus sign with an upside-down triangle in subscript (mid screen on the left side. To lovesdaap...: to do fractions simply press the classic divide button. That is, to enter 8/9 as a fraction, click 8 then ➗ then 9, then click the small right arrow.#### Beautiful! 5/5

By angeladaviniThis is hands down the best grapher I've ever seen - easy to use design, yet also powerful enough to handle anything you'd like! I only wish it could do 3D graphing#### 😍😘😍😍😍😘😘 5/5

By % Super Gamer %I cannot express how much I love this thing. So useful, I use mobile and web version.#### Great 5/5

By sman72Finally, a graphic calculator for 21 centuries that can be used in school :)#### 4 stars 4/5

By Anonymous#456It works great except for the fact that you can only do a square root and not anything bigger like a cube root (or smaller I should say)#### Amazing App 5/5

By Shagwell mcgeeWhoever designed this app legit deserves an award. One of the best functioning apps I've ever seen, even better than a TI calculator. Thank you Desmos for this awesome app!!#### Great app 5/5

By DincdsdcujxBest graphing calculator app ever! I was in a real bind with my homework since I did not have a graphing calculator, but this saved me! I would highly recommend it!#### Bad 2/5

By Madminer48Has no table or anything else all you can do is look at whatever you graph I guess it's kinda useful but I mean that's the only thing it can do.#### Tool of choice for math students and teachers 5/5

By Martin joyceA free app for your phone that is a million times easier to use than a TI 83 graphing calculator. Students used it in class to type in linear functions. Great online support also.
