This app is great! What can’t it do?! Why buy an expensive graphing calculator when you can download this app? The interface is more like what you see in class or your text book, and you don’t have to learn TI coding for it to do what you want. I have used it quite a bit for college algebra, trigonometry, precalculus, and calculus. I tutor math and it really helps visualize some of the function manipulations. It is a very powerful tool and a fantastic teaching aid. In lecture, my professors have asked to borrow my iPad so they can project the Desmos app’s graph for the whole class to see. The pinch and zoom feature is really nice and so are the sliders for variables. I do my homework using Notability and can copy and paste (or screenshot and paste) the graph right into my homework assignments. I also just discovered the derivative function. This might be wishful thinking, but it would be nice if there was an iPad/stylus interface where you could sketch a graph into Desmos and maybe have its derivative/integral shown. Overall the app is fantastic, I highly recommend it to any/all students taking math. It has taken my understanding of certain math concepts to a whole new level!
the latest update says “now with ios 9 support” but it ain’t mf 2015
Black bars on top and bottom on iPhone X 1/5
Have the developers ever heard of uneven screen degradation on OLED screens? It’d be really cool if the app was actually optimized for the X instead of those #000000 black bars.
Don’t know what’s going on. Every 3 minutes the app freezes. 1/5

Mr silvas class rocks with this brand new tool. Totally tubular dude!
It won’t open 1/5
Whenever I try to open it, it just keeps on loading forever. I can’t use it at all.
Best School Graphing calculator 5/5
By Half of my bean salad
I'm in a math 108 course in college, and this is the easiest, cheapest, sleekest graphing calculator around. User interface is bueno and well thought out. I can easily do my Maths now
I found glitch 4/5
If you zoom way out and then zoom in, your creation is stretched
Blazing fast 5/5
By Eli Luberoff
Desmos is bae
Great app but… 3/5
Whenever I try to get I to the app, it either crashes, or doesn’t let me in. I use des is on the computer all the time, but when I needed a relient portable calculator, the app didn’t do much.
Can’t get inverse tangent 4/5
The inverse tan function appears to be faulty (though I’m not a mathematician). For example, the simple trig coordinate problem tan to the -1 (inverse tan) (4/3) to find polar coordinates for the rectangular coordinates ithe point (3,4) returns 0.927... insread of the expected 53 degrees. A different calculator give the correct answer (53 degrees).
Wow works great 5/5
I love it so much and it helped me prepare for my math test. Thanks so much! I aced it!
Missing One Thing 4/5
The app is great but it’s missing a share feature, so that people can share their graphs just like the online version.
No need for expensive graphing calculators 5/5
Ever since my time in trigonometry I have used this app to pretty much do my homework for me and it has gotten me a 100 on every paper if I missed that question that was because I didn’t know how to operate the calculator which means I wouldn’t of been able to do it in the first place but this app is by far the best FREE and
There is no cube root option 5/5
By MGA student
I love this app it really helps me visualize my math but there is no option for cube roots and I know that you can just cube the other side of the equation but it is really frustrating for some things
By far the best 5/5
Awesome graphing app! I highly recommend this to my friends and they absolutely love it. Only wish it’s adapted for iPhone X
The mother of all graphing calculators 5/5
Amazing what this App does. I was amazed at the curve fitting capabilities and the calculus (area under the curve/integral) capabilities. I encourage users to see the calculus example. I used to do all these with numerical methods in huge Univac computers and now comes in an App. Amazing. Keep up the good work and thanks for sharing. It’d be great to be able to cut and paste or import rather than input one by one the regression data. Also it’d be nice to be able to cut and paste the formulas.
Awesome but needs additional features 5/5
This is the best graphing app on the store however updates containing new features are scarce. Complex numbers would be nice. In addition a function that can find the root of another function and return the root as a number. These are examples of features that I’m sure a lot of other users would like to see.
Great app very useful 3/5
By Cringy critic
However 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.
-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
Hey 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
Honestly 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
This 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
Best graphing calculator period. And it’s free? I wish I could give them more stars.
I can finally check my hw questions easier
Horrible App 1/5
By Sherman Liang
I don't have a phone so I can't use it. HORRIBLE APP.
One suggestion 5/5
By Heli 3
You guys should really add a camera feature to scan these problems!
Trig functions don’t work 1/5
Pretty 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
This app needs to fill my iPhone’s screen!
Amazing Awesome 5/5
I like Hummus and Desmos ya know what I mean
Fix the sim, cos, and tan buttons. 5/5
This 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
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
Doesn't load properly but works great when it does
I don’t know how math students survive without this thing. It makes all of my college math classes manageable.
By jendkngfid dj
I had algebra one homework and I didn’t have a graphing calculator. This saved me
Excellent graphing tool.
Great app 4/5
I 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
It's really easy to use 😁
Reliable app 5/5
It just a works fine!
It's so silky smooth 5/5
By pizza lova
this does exactly what is said it would do, love it for math homework
Great app! 5/5
Awesome graphing calculator. Sliders are the best!!
By Moorgan Hart
Just 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.
This app doesn't work 1/5
This app is terrible
Cool addition... 5/5
By Person #4792
I 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
