Graphing Calculator App Reviews

OK, CAN SOMEONE PLEASE TELL ME HOW TO PUT IN ORDERED PAIRS?!? I'm not in trig or calc. I'm in algebra. I cant find a thing! There is no line of bet fit, but I could figure it out is you JUST PUT IN SOME ORDERED PAIRS! Geez., what else can someone ask from a graphing calculator? This calculator is not user friendly either. Ha ever heard of INSTRUCTIONS???

The keys are zoomed in and many are missing. Making the calculator unusable.

Very well built and easy to use.

This app is is extremely capable in all aspects imaginable. This calculator is a must have for anyone in high school algebra or higher. It's solve for x capability has saved me countless times and the graphing is incomparable to any other app on the market

Could not use functions. No help screens. App froze when I tried to email. Deleted app. Want refund.

FiXED For me it is extremely hard (nearly impossible) to put ' . ' (decimal point) on the handwritten calculator. Am I the only one having this problem?

Well it has a graphing calculator, that does not have almost any of the calculations that a regular graphing calculator has, so.......

Cannot access functions. Tried to email support but email freezes. Wnat my money back.

Very intuitive design. I tried it out as a backup for when I forget my graphing calculator, now it's my goto choice for graphing. It didn't take much time to realize the excellence behind this calculator, I love how easy it is to use, the look, the way it displays both the equation and the result, supported features, everything

Far better than the default calculator app. I definitely recommend it!

Tried to solve for 9 variables and it did not do it

I picked up the hobby of designing objects for 3D printing and I needed a good calculator for trigonometry. Rather than spend $100 on a graphing calculator I bought this app for $3. Works great so far

Need to have some direction to show all features of the calculator. ....... Can't find the trig functions!

Works great!

I’ve been using this calculator for a long time and they do a really good job with it. It is so much easier and more reliable to calculate grocery or restaurant bill shares on here because you can actually see your entire formula string. The UI is also super nice. Strong work!

It didn't take much time to realize the excellence behind this calculator. The apple calculator is quite annoying because I have to rotate it here. Very useful and calculations are quick. Love the deisgn with 5 types of calculators.

Used to be my favorite quick calculator. Then I bought the iPhone 6 plus and I cannot use this app it zooms in on 9 keys and I cannot see anything else. Please fix so I can use it again.

It is so messed up on iPhone 6 plus you can't use it

This app really needs the ability to graph inequalities.

Wish I had found this before I failed my test, you type in you problem and it solves it for you, the best part is you can see step by step to help you see how the answer was solved , love it .

Very nice app. Ran into a bug on iPod Touch 5: Equations like -y+tanh(x)=0 fail to graph where the argument of tanh() is negative. Looking forward to a fix.

I found it impossible to graph a cube or above root on this app. I love it for everything else, but that's preventing the fifth star from being awarded by me.

Many of these reviews are complaining about the function of this calculator. I think that they have forgotten that it is only 3 dollars! It is an excellent value for a refined product that includes a graphing calculator, as well as a scientific calculator that is much better than the default. I would definitely recommend this to the average student who needs a cheap calculator for homework. Remember, though, you can't take this into most tests, since it is on a phone.

I need more functions for solving linear equations and this calculator for $4.99 is not good

This is probably the best scientific calculator app on the store. It's got a slick interface and the widget makes it very useful. Note: My review had originally complained about some changed functionality in the widget; this is not a bug, as Apple changed how it is supposed to behave. The developer let me know how it works now, which solved my issue. Thanks!

Overall satisfied

$3 wasted as far as I'm concerned ! NO support or documentation help, even on the developers web site. Not everyone who needs one of these types of calcs, is a rocket scientist who knows how to use one !

Useful tool to help my kids understand quadratic equations. When graphing multiple quadratic equations, color coding the equation and graph would be useful. Example I was showing my kids what happens when change only a, or change only b, or change only c.

There needs to be a way, or more obvious way to do absolute value equasions.

This app is terrible. I can't even write my own math problem. It keeps disappearing and I cannot find anything on there to tell me how to do it. It does nothing it said it was suppose to. I want my money back.

I have been using this Calculator for years now. It saved me in a lot of exams and the most thing I like about it, is the ability to edit the equations, as well the fact that it comes with linear equations solver and quadratic equation solver. Can not recommend this enough. I rarely write a review, but this one deserves it!

I was expecting an excellent calculator app for $3. It could be improved drastically. For example, it could have themes to better layout the calculator (Ex.: TI-84 Plus). It is just very confusing. DO NOT buy it it is crap!!

This calculator does not have the applications that I need for my trigonometry class and is most definitely not worth $3

Everything you need pretty much, but a table feature in the graphing calculator would be greatly appreciated. I think it you guys should add that.

This calculator is really useful to me as a computer science student. It has a wide range of functions and works great. Layout is very nice. Simply an amazing and very useful equations calculator. It is an invaluable asset for anyone doing high school or college level

Didn't like how complicated it is and doesn't halo me with my algebra

I work as an electrician and needed this for my schooling as there's a lot of math involved. I love the fact that it's an all in one calculator so that you can do graphing. solve equations step by step. It's by far much better than the default Calculator app that comes on the iPhone. The only negative was I was never able to use it on exams as they might think you were cheating. but At work or in the trade it doesn't matter. Calculator is Calculator.

This app has a horrible support system that never gets responded to. The graph always makes the app quit (why I used support). I told them to respond to my support email and they never did which shows they have horrible support. This app has a terrible layout where I can't even find an equal sign for graphs. Want a good graphing calculator? Get the free ad-less Desmos app.

It does lots and I rarely need more. love the fact it's now retina.

Let me know what I have to do..

Poopy app to hard to do anything

I purchased all of the calculators some time ago and now, after the last released upgrade I am being asked to pay another .99 for each calculator??? Not cool!

It's an Amazing app so far the only thing I have to say is there should be a table setting with the graphing function.

It needs < and > and y and z for graphing calculator and other calculator!!!

This app has helped me so much; it does everything I need it too. I just wish the home screen icon was upgraded a little. All of my apps look nice and fresh except this one :(

It's a good calculator and has helped me a lot with Geometry and Algebra. I have learned how to figure it out, for it can be complicated. My suggestion is to make it less complicated.

My son downloaded this for his pre-calculus class and he said it isn't able to do any of the things he needs done. $4.99 is absolutely ridiculous for something that doesn't work as advertised

I haven't revised my review in 12 months because the same problem still stands. Because of this, I'm also changing the rating to 3 stars. This is a simple problem with a 5-minute fix. It's annoying, it's hurting my eyes, and it's making the app look bad. It's been more than a year since the iPhone 4 came out. The app still doesn't have retina display compatible graphics! Otherwise, it's a must have app. Also, to the raging girl below, you have never used an actual graphing calculator, have you?

I can't put x+y =9
