GeoGebra Graphing Calculator

Useful, BUT the developers need to treat exceptions NOW. I was working very short numbers like 1.E-9 and suddenly the app freezes my cellphone system. When it was back to work, my SD card (64 GB!!), where the app was installed, crashed. It's empty but says there's no free space. Before the crash, it had only 5GB occuped memory. That's not the first time this app crashes my system, but this time was critical.

Essential tool for visualising functions. Have used geogebra as a learning aid for myself for years. Although drawing functions by hand can be good, this allows for easy adjustment of numbers and variables to identify what numbers influence the way the graph looks. Used the desktop version in year 9 to fully understand porabolas, it was much more efficient and neat than drawing every variation and meant I could overlap multiple functions.

Good app with both plenty of simple graph tools and also abundance of methods that I do neither know nor need to know, but sit there just in case. But there is a bug that occurs on Xiaomi Redmi Note 4: 'x' and 'y' symbols just disappeared from the first keybord. Just a visual glitch, but an annoying one, please try to find what the issue is.

It's everything I need from a graphing calculator, but not all commands are working which also means looking at other people's graphs might simply not work

It is an amazing and extremely useful app. But there are some issues with the background when I am using dark mode on my phone. The background swithces rapidly from black to white and vice versa when I try to move through the coordinate system, as if it is flickering in those two colors. But other than that, the app works perfectly.

An excellent app let down by abysmal UI. For example I can't enter commands like I can in the input bar on geogebra classic on desktop, instead having to input text in an extremely clunky input system that tries so hard to be fancy that it's barely usable, and I can't even use my device's keyboard! It's best to edit on desktop, save, and use the app purely for viewing, even for minor edits.

I am satisfied but there is only one problem that it shows a rectangular scre5 when used in smart phones. It makes difficult to show the whole graph then. Can you please make an option to show the graph in square shape. And also that as you zoom out if you want to show 1,3,etc you have to again zoom in. This makes it difficult to show the whole graph on a smart phone? So please can you try to solve that problem also. A humble request from your app user!

I used this calculator since my device doesn't come with an inbuilt one so. It's smooth the way it is supposed to be, just a little hasslesome sometimes. Though, as a strong opinion, I think that this might be for beginners in ths particular field. Although, I would've given 5 stars here than 4, only if it had the right functions (programming wise) for 'em. The website's good though (For elites too I'd say).

I'm going to say this. The app is good. And I appreciate the fact that they remove features to have it allowed as a graphic calculator on tests. There is one problem. It would be good if there was a message somewhere that CAS calculator has removed options. Also CAS calculator seems to be missing the tool bar, at least for me :/

Like it, but would have liked the graph zoom to (optionally) allow for non fixed aspect ratio too. Of course you can manually scale the function itself with a factor, but that seems a bit silly... would also have liked to select the sizes of the dots, or have them following the line thickness. And would have liked an option for input and output in other bases too. 1/2h=0.8h

Hi devs I'm someone that doesn't have a PC nor can get one at the moment, and this app has been of huge help to me in my studies The amazing thing about GeoGebra is that it allows you to see both the graphical and analytical side of maths in one place, and that's what makes it BETTER than other graphing calculators. You say you removed features to make GeoGebra more accessible, but this is an amazing app BECAUSE of it's many features, NOT despite them. Don't fix what isn't broken please.

Super! But recently, as I updated the app, most of the tools in the toolkit dissapeared. That is, drawing perpendicular/parallel lines, setting angles and others. Now they are only available through functions which is way more inconvenient than before. Asking to bring them back. Thank you) Oh, also it'd be great if there were a more feasible way to view constants. They ceased to show in the calculator

Very useful, and overall a great app. Heres two bugs i noticed 1)Its not possible to select only parts of an equation. (Not sure wheter this is device specific though, I can [partly] see the tool to change what is selected but can't access them) 2) The smart insertion of parenthesis is usually quite nice, but it can also be really annoying, not letting you edit equations correctly.(If you could add an option to disable it that would be great) Btw: The CAS app has the same issues

Such a powerful tool. I am literally always impressed by how much this graphing app can do. I graphed rational curves to help me find asymptotes. It's also immensely helpful and very easy to graph polar curves. the calculator quickly knows what you're trying to do most of the time, the only exceptions are really my fault. Keep up the great work.

Intuitive and practical to use. A way to calculate function limits would be useful to have (also an eye-friendly dark theme?). There is a small bug I noticed. When I have a function that intercepts with the x and y axis at (0, 0), it doesn't show the intercept point as (0, 0). It shows something like this as the intercept point: (0, 0.000000325). Small bug but it can easily confuse people

This is a good app but the input (keyboard) is just so frustating to use lmao. Just a suggestion, let the user use system built-in keyboard for typing text, and then add the math symbols on the screen above the user's built-in keyboard. You can wrap those symbols in a horizontal scroll view to save space, or just use smaller symbols. It's frustating and confusing to switch between qwerty and math symbols input.

I personally haven't updated in a while so I don't lose the geometric features. Many constructions and the like can be inputted algebreically, but it is far more convenient to have the ability to have them done for you. I ran into an issue creating points on the intersects of self-intersecting plots, as the point will attach itself to a single branch and avoid any intersection. Overall very useful app, but please don't remove the geometry features.
