It's pretty good 4/5
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
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
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
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
Love this graphing calculator, never have any problems with it
Way easier to graph on than my TI84 calculator. The shading effect is also useful.
Best All Time Math App 5/5
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.
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
Highly Recommended all Students to use it for trigonometry class!
Best app for graphing and teaching others!
This app is great 5/5
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
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
My friend jace and I play all the time
Absolutely Phenominal 5/5
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
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
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
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
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
This app is very helpful but it would be more if y’all could put fractions to be used
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.
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
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)!
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
this is a fantastic math app, it replaces my calculator as well
Great app!!! 5/5
OMG it is the best graphing app!!!
Where’s the yellow? 2/5
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.
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
By GAM1NG MAST3R
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.
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
It’s just a calculator
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
Exactly what I needed.
This is probably the worst thing I have ever used on the App Store
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
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)
This app is super awesome
I highly recommend it
Great graphing calculator 5/5
Great graphing calculator I use it everyday.
Good, but 5/5
The app is great, and I would highly recommend it. That being said, it would be great to have an option to change the keyboard size. Right now it is almost unusable small.
Don't waste you time look somewhere else 1/5
By Frequent traveler2012
Tried my best, as worthless as worthless could be
Logs me out every time I close the app 4/5
Signed in with Google in the app, but after closing the app, the app will forget who I am. I have long account log in credibility, so please don't do this to me!
Desmos is my life 5/5
I need say no more
Best Graphing Calculator 5/5
Wonderful for school and understanding how formulas work 5/5
By MGA student
This app is wonderful and a large part of why I don’t hate math and now actually understand what I’m doing. I can check my answers agents the original problem to check my solution and through messing around changing signs in an equation I am been able to visualize equations that would otherwise be as number soup to me.
I can’t wait for possible future updates it would be useful to be able to have an option to see the center points of conic figures as well as the foci. This is a great app and well made and I hope to see future improvements such as this.
Yeah sure 5/5
By Master of the TRUTH
This app works pretty great considering my middle school math teacher told me to get it. I only know how to do a couple of things tho, since I’m only in algebra 1 advanced, so idk if some higher level things work or not.
