Would be 5 stars 4/5
Tais would be an easy 5 star review if it had Apple Pencil support. Being able to write complex equations rather than type would be fantastic!
Arc sine function 1/5
Arc sine, arc cosine returns the wrong values.
I hit the function button, pressed arc sine, entered 0.5, app returned 0.5…not 30
Just Super 4/5
By Cid Hamete Benengeli
I put this to some pretty specific and odd uses at work (carpentry; the explanation is lengthy and boring) and tried at least 20 different calculator apps in my search for just the right one. This one’s a keeper because 1. you can give it expressions in any form you want, which seems to me like something any graphing calculator should be able to handle and 2. it works offline, which also seems like something any calculator should do, since an app that has to ask a server to do calculations isn’t really a calculator, is it? The app is fast, the sliders nifty, and the layout streamlined. I also like how easily customizable the display settings are, but I wish that some of these settings, especially Reverse Contrast, were persistent. This, plus a few tweaks to Reverse Contrast, would effectively give the app a dark mode, which is never a bad feature for an app to have (and all with minimal effort for the developers—just sayin’). I also wish that the little box that displays the coordinates of a point on a line would stay visible until you tap again, not just until you lift your thumb up (there’s a way around this, but it’s not intuitive at all), and that it would move when you adjust a slider. Aside from these minor gripes, this app is super—heck, I’d pay for it.
Not good as website! 3/5
Hey there, I’ve been using desmos since 2020 on website, and it has many and good features, i wonder why some of them aren't in the app? Like drawing sequences, and why it keeps log me out when i open the app again. I hope you can fix it as soon as you can!
It’s a life Saver 5/5
It helps me be able to solve equations that I often have trouble working with. This helps a lot.
An essential tool for every math student 5/5
Really, you can’t get wrong with Desmos. If you’re not using it, are you even a math student?
Down with TI 5/5
By CFlo SD
I don’t need my TI-89 anymore, I took calc ii over ten years ago, but only use it for basic accounting and random calculations.
Downloaded this app to support Desmos’ philosophy on affordable and equal education.
Desmos is good. 5/5
By I Perm
You can use this offline. It’s good to use in math class when they block my 4G. It does everything you need to do. You can use it to cheat on you math tests if your teacher is chill. Helps me with graphs. 5/5
By nickname lol es
It bombed my city smh
Sexiest graphing calculator there is
Need copy and paste function from external spreedsheet 3/5
This app could be more powerful if you can import data from other files, or simply just a copy&paste function, which is not included.
This app is horrible 1/5
It killed my entire family…
trig functions don’t work 1/5
stupid thing got me a bad grade on a trig assignment cuz it was giving me wrong answers
Trash app trash devs 1/5
By hooman not a dogg
Dhar Mann hates karens
Great graphing solution for mobile 4/5
Very good mobile port of the browser calculator. Would like to see more Greek letter support and improved highlighting ability, otherwise a quite powerful graphing engine.
Good for Graphing and Algbra 5/5
By Doc. Okc
Im horrible at math anything past basic math and multiplication and division I dont do good in and if it wasnt for apps like this I wouldnt be able to pass high school math so thanks to the developers ⭐️⭐️⭐️⭐️⭐️
By P Panch
Desmos helps me to see how things can be graphed and how equations can be seen visually. Desmos has the ability to give you more answers that other apps can’t. Go Desmos!
Desmos is bad gives me headache ☹️ 1/5
Take this app down or you will be hearing from my lawyer
App of the Year 5/5
By IG kxng_aleexx
helped me get a A+ in pre calculus
Cool thing to do: do Polar: rose, but replace sin with tan
Amazing app it saves my life
Bad app 1/5
Name it different bozo
The best. 5/5
By challenge me bro
Regular kids use their Texas Ti-84 Plus’s only the greatest use the desmos apps
It’s good 4/5
By The Sheep Man
But the fact that it deletes everything after switching apps for more than a minute to try and get more numbers for calculations makes it really really annoying other than that it is the best option out there
Good app 5/5
By shatks 12345678066
I love this apps
Please cut the title screen duration in half, at least 5/5
I RATE THIS APP ONE STAR 5/5
I was forced to download this app and I despise every second of it. I have no free will and am being forced to write a review for 5 stars. I cannot believe that I have to help boost this app with a five star. It is hot garbage and can go die in a hole. I will delightfully delete this app when summer comes because I hate it with a burning passion :)
Couldn’t ask for a better graphic calculator 3/5
UPDATE: export function removed. Not good. Can take a screenshot but that’s not the greatest solution. Updated to 3 stars
loved this app and have used it for years to visualize business expense scheduling decisions. It’s so intuitive and is extremely easy to use. I just redownloaded it and there’s even more powerful features now that I have to try. Easily the best graphing calculator on the App Store.
Powerful calculator and visualization tool 4/5
I love Desmos, use it 100% of the time instead of the calculator app that comes with iOS. I really really want a way to hide the graph window, though, so that using it as a regular calculator is easier and takes up the whole screen
Best app ever 5/5
Seriously this is the best app I have ever downloaded on the App Store.
Thank you developers for making such an easy and powerful app. My 8th grader now understands graphing. You guys are awesome!
fantastically great 5/5
By Ali Ghasemian
I am a physics student and math is the language in the realm of physics. I use this app to help me understand math better. It is great both in accuracy and being so easy to use. Thank you so much.
Light as a feather 5/5
the calculator is great but the thing i love most about this app is how little storage it takes up. it’s like it’s not even there. i wish developers would focus on this more, since apple started messing with our ability to relieve storage space by transferring files off our several-hundred dollar iphones, pushing us towards paying more for their icloud service instead. thanks for this easy app!
Absolutely Phenomenal 5/5
By Barnibus Pipinpadaloxicopolis
Love everything about this app. I’ve used the browser version since middle school and the second I had a smartphone I was using this app.
I’ve been using this for years all through getting my ME degree and into my job as an engineer. I’ve even used it to keep track of things during game night with the family!
Every once in a while I might notice a feature missing but without fail that feature appears in the next update.
Love the app, love the developers. Honestly not too sure how this app is free but I sure am glad it is for all of those students in need.
Big problem 5/5
The floor function is broken, and I’d assume the ceiling function too. Asking for what x makes floor(x)=2, it’ll graph x=3. It probably wants to graph x=2.999999, but something infinitely close to 3 is 3. When doing recursion where the function has to do with floor, I can’t expect it to reliably tell me if the 10th recursion of a fraction multiple of a floor function is going to be the smallest possible value for x. Please fix!
HAS SAVED MY ALGEBRA GRADE 5/5
Me being in 9th grade starting algebra hasn’t been the easiest thing but this app has helped me a whole lot I’ve recommended to a friend and they said the same thing it’s amazing much easier to understand and it’s FREE in my opinion it’s the best of the best but all in all I highly highly recommend it😁
Sorry about my earlier review I didn’t notice the cubed roots sorry this is five ★ ★ ★ ★ ★ app.
No longer shows coordinates 1/5
By Review Person¥
No longer shows x and y coordinates when tapping on the graph line.
Feature Request 4/5
I've been using this app for years.
It'd be nice if you could resize the calculator window to be larger. The buttons are small, and sometimes I just want to use the calculator.
A guy with fat thumbs 3/5
By Anxiously awaiting a fix
This is less a review, and more a request for a change in features.
My dilemma is this: When entering text in a given calculation bar, it is sometimes necessary to select text to make changes. On the iPhone, this is done by tapping with a finger. Then, to continue the editing process, select the end of the text to continue typing numbers (etc. ). That puts your finger dangerously close to the “X” that will delete all of your work (when all you really wanted was your cursor at the end of the line). Perhaps switching to a “swipe to delete” setup for ridding unwanted calculations would spare those around me an avalanche of dismay?
An absolute joy to use 5/5
Everything about this calculator is wonderful. It’s one the most powerful 2D calculators i’ve seen. The UI is intuitive and easy to use. The only feature i’d recommend is the ability to enter polar equations in more than just r= form.
Awesome, but some slight issues 4/5
Formatting can be kind of annoying to understand sometimes. Could use some more tutorials.
Also, DO NOT SIGN IN!!! Signing in breaks the app! If you sign in, you can only press one button and then the app becomes unresponsive. Absolutely ruinous bug.
This is the best free graphing calculator. Period.
Great app 4/5
I use this app all the time for school. Would be great if I could share the app as a pdf or png on an iPad or iPhone however.
Very Helpful 5/5
By Just a high school freshman
Incredibly useful. Pretty much what got me through my freshman year Algebra course.
By Tin Schroeder
Every time I add any value into the x or y axis and back out, it changes to some crazy high random number. I despise whoever created this app
The greatest there is 5/5
I’m a university math student and as such, I’ve had a deep appreciation for Desmos since I downloaded it in high school. The incredible amount of functionality in this app is truly what sets it apart from anything else I’ve ever used. From implicit curves to parametric equations, from multi variable integrals to combinations/permutations. As it is, Desmos registers f(x,y)=g(x,y) as an implicit curve and even r=f(θ) as a polar curve. The one thing that would make this app unstoppable would be the ambitious feat of registering complex numbers. If this is ever accomplished, I think I may die.
Love Desmos, but terrible for iPhone 2/5
By Nick Name, Esq.
I think Desmos is fantastic, and works so well on the iPad or computer. Just don’t bother using it for an iPhone. The buttons are so small that it isn’t worth your time and there is no landscape mode. Not really their fault but I would love to see a port with those features
Great App 4/5
This is my favorite graphing calculator but the one thing i think it needs is a button to save the settings that i change for future use.
