Once I figured out all of the setting choices, I have had no trouble with this app. The ads are unobtrusive, and I get the answers I need with the work shown so I understand the steps. Fantastic app that is helping me through my college courses!

Very well designed and developed calculator for instant graphing. This was well thought out and hence has a very intuitive user interface, full functionality and great viewing abilities. Good job developer(s)!

I've been using this app for about 5 years now, since my senior year of college. My graphing calculator broke during my last year studying Electrical Engineering and I couldn't afford a new one. Luckily for me all my exams were either open everything or closed everything, so during the open everything exams I would use this app to solve any necessary problems since it has everything a TI 83/89 would have. Highly recommend this app and donating once you get the chance, best calc app on the market

The best and only calculator I would ever need. Basically got me through college. The app feels complete, even without the pro version, which is always a plus. Shame it can't do calculus though, but that's probably asking too much.

Everything is wonderful in this application, frankly, amazing work, and there is no better application than it, as far as I know, only if you would like to delete ads, as they are very annoying, especially since this application is scientific. I see that these ads degrade the value of this science

Very useful and accurate app. I have used it for control systems design, very helpful to solve polynomials, partial fractions, rational functions and factorization etc. You can sketch multiple & complicated functions on a single plot with any range of independent variable. Moreover, it also gives you table of computed function values over a smaller step of independent variable. Easy & faster way to analyze & plot functions. I recommended this app to my students also. Strongly recommended app.

Starting off with what I think anyone downloading this app to cover for a real calculator in stats needs to know, this app will not get you perfectly accurate results, using it for complicated math or stuff like stdev CV ect will results in anything from tenths off % to first decimal off, and I checked agenst my Ti-84+, what's enough get answers marked wrong for me, so don't depend on it. Now moving on from that, if you don't need stats or decimal accuracy, the calculator works fine outside that

Very useful and handy for people who can't do lots of calculations but can visualise. However I really dislike having to purchase the full version, no matter the number of benefits. There seem to be a bug where I can have functions and constants without the pro version.

1. Well designed app. 2. I find three work spaces in this app very handy. 3. Once the app is closed, and relaunched, All the previous calculations are preserved. 4. Adverts are non-intrusive in free mode. 5. Graphics mode is also excellent.

Fast, efficient, fairly easy to use providing you have the knowledge in maths. I'm in my last year in high school studying maths, it's extremely helpful, the only thing I haven't found is derivatives (I might have missed them), but even without, it's a very complete app. I'd really recommend this to anyone looking for a good calculator.

The app is capable to show the graph of a variety of scientific functions. It permits multiple functions in a single Cartesian coordinate system. It can zoom in and out and can find special points such as roots and intersections. It can deal with superimposed functions and the products of functions. The app has help me with understanding combinations of functions which is important for highschool and college students.

Have been using this app for three years. Helped me through my school and uni. The title might be graphing calculator, but I always using it as a normal numeric calculator for counting everything. Maybe the only complex calculator with answer that you don't have to click 'submit' first. It might sound trivial, but this difference just made this app the best calculator ever!! The ads aren't a disturb at all. Really, the developer deserves my very huge thanks for making this superb calculator.

By far the best in terms of being able to directly and simply entre and syntax f(x) for plotting and it immediately drawing and showing pertinent intersection points with coordinate axis etc without even having to use the manual trace function. Easy scaling to visualise detail in the plotted function using simple pinch-zoom! This is on another level compared with every tool I have tried this week. It graphs along with you, as you syntax your f(x) 😁

This app converts your cell phone in a great calculator, you have the regular options in a scientific calculator, but its nesting capacity allows you to perform complex operations, also if you change a value it makes all the calculatios again, useful if you need to use a formula several times. It has adds, but they normally stay at the bottom of the screen

I've installed this app on every phone I've had for about five years now. This is maybe the most useful piece of freeware I've ever had the privilege of using. The interface is excellent and intuitive. I don't use the actual graphing functions much personally, but there's nothing like a calculator that writes our all of your calculations visually as if you were doing them by hand. Now that I'm out of college I sold my TI-84 because I know I always have access to this app. Does everything I need.

This could be a five star app, except that it keeps dropping expressions. They disappear when switching between workspaces, adding a new expressions to the current workspace, or seemingly when it is simply going to be the most frustrating. I'm using the advert version, and I know some people might think that I should pay for the full version if I want it to work; well, to these people I would say: why would I pay for the full version when the advert version doesn't work?

I don't usually give ratings but here I am! Along with graphing any equation I've come across to graph, it will function as a regular calculator and solve equations with the solving process lined out. It also has a table that I'm not familiar with but I'm sure it works great. On top of that, this is all on the free version. There are probably a lot more amazing features on the paid version. Thanks😊

Very surprised and delighted to find a calculator app with so much functionality. I'm used to switching between different calculator apps with different individual functions when helping my kids with their homework. With 3 different workspaces to work in at the same time, big plus. Awesome calculator!!! Would recommend to anyone, especially students.

I love everything you can do on it. It definitely gives you the flexibility for almost everything! -(Update)- So originally I gave this calculator app five stars, and YEARS later I'm giving this an update. I've been using this calculator for years and simply it will do just about EVERYTHING you can throw at it. Its so pack full of features and options. From simple computational tasks, to inputting complex functions. I only wonder why this app is free... oh yeah it has ads, but its no bother.

Update to the update: Thank you for telling me that the Pro version works offline; however, this does not solve the problem of the FREE version not working EVEN WHEN ONLINE..."network connection error" when on Wi-fi network. This calculator has always worked fine in the past whether on network or phone data. Now it does not work. Update: I haven't been able to use this due to "network connection error". It doesn't matter whether I am online or not, same message. I've deleted and reinstalled. No luck... I used to love this app and recommended it to all of the students at the college where I work, but Issues have reduced my ability to promote it at this point.
