Can’t find intercepts!

I love Desmos. I really do. It’s hard to find a replacement that allows you to graph multiple functions. Right now, as I am preparing for my AP exam, I am so incredibly frustrated that I can’t hold down on the screen to identify a point of interception. In the past, this feature worked without a flaw, and now, I have to zoom very close into the graph to find the intercept myself. Please, amazing desmos engineers, fix this feature! And I will love the app unconditionally once more :)

Great but could use one extra feature

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.

The greatest there is

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.

A guy with fat thumbs

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?

Very useful but has a few fatal flaws

I've been using this since I was a high school student back in 2014. It's come in handy many times, but it's 2022 now. If the developers of a math calculator can't make it so my current equations are stored in some temporary cash instead of getting wiped out from ram then I have no idea what you're doing. If you're trying to have charged me on some premium stuff I'm having none of it. I enjoy a good free graphing calculator. And personally I would love it if my equations would just stay stored whenever I close the app in the boot back up storage is fast these days. If Desmos does not fix these issues I will make my own graphing calculator app for free and I will make a superior just to spite you.

Just Super

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.

Just Super, But Could Use a Couple of Little Adjustments

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, meaning they would still be as I’ve set them after I close and re-open the app. 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 (I’m surprised they aren’t just calling it “Dark Mode” as-is). 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.

Amazing, plus, here’s a lil’ tip

This app is amazing, I use it all the time and its pure calculating power along with its saving graphs feature is why I’ve never even thought of deleting it ever.But here’s a small tip for all of you reading this:It may seem that there is no antiderivative feature, but that’s actually wrong. To be fair, you’ve got to know a bit of calculus to know this one, but it’s a simple trick. To get antiderivatives, you’ll need to utilize the first fundamental theorem of calculus, which says: ₓ∫f(x)dx=∫f(t)dt ᵃWhere a can be any constant. So if ya need indefinite integrals of functions, use that format. Don’t worry about the value of a. Remember that a +C is added at the end of each antiderivative because it is not needed to calculate regular derivatives.

Light as a feather

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!

Dude, Desmos is so hot.

Literally if I could give this program 10 out of 5 stars I would. This bodacious program has everything you could ever dream of, it’s easy to use calculator and graphing functions is enough to make a grown man cry, and that’s ok. In fact I have cried, every night, since downloading this app. Tears of joy just freely fall from my eyes as I use this scientific calculator to tackle harder and harder functions. Is this what love feels like? Should I see Desmos as the light at the end of the tunnel? Will they leave me for another, creating a love triangle that could possibly be published into an award winning YA Fiction Romance? I do not know. However, I do know that if you download this app you will not be disappointed.

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. Tables: Input and plot data, or create an input-output table for any function. Statistics: Find best-fit lines, parabolas, and more. 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. Accessibility: Read and edit math using a screen reader or a refreshable Braille display, and use audio trace to explore graphs and data through sound. Offline: No internet access required.
