This app is the most amazing thing ever. Other than the fact that it puts you through an ad when you open the app, this is easily the best graphing calculator that’s mostly free. You can’t graph certain things but most everything is free. This is such a great app, and I have so much fun creating my own calcular and deciding all the fun colors. It also has other feature that standard graphic calculators DONT have! Overall, it’s an amazing app- I am a student and it’s such a great student calculator!

I paid 29 dollars to have this forever. And compared to playing 100$ for a real one that’s a pretty good deal. bUt, I’ve run into some issues with the calculator. Specifically when solving lengthy equations, it never carries the negative through the problem. For example, if I were to put in -3•4 I would get -12, but then I multiply my answer by 8, (-12•8) and it would give me positive 96, rather than -96. This has caused a few issues on some assignments for me but once I figured out what was happening it was pretty easy to continue. I also have a hard time looking at graphs when I graph them. I’ll put my equations into the Y= and it will graph fine, but I can never see the full graph, and because of that I can’t find the intersections and all that. Other than that it works pretty good, I just try to use it for the more basic stuff that my phone’s calculator can’t do.

Developer Response ,

Thanks for your feedback.
We tried to replicate your calculation regarding your negative sign problem.
After we multiply -12 with 8 in the next line (so there is -12 and then in the next line ans*8), the calculator gives us -96.
Can you send us a screenshot of your calculator screen so we can take a deeper look into it?
For graphing you can see the full graph by changing the window settings or use one of the zoom commands, for example, "zoomFit" should work to show the whole graph.
We would be happy to assist you with this in more detail. You can write to us at

I downloaded it for a reason

This app has a very clean and professinal look to it, very pleasing to the eye, and the pop up window is a nice size. The color customination at the beginning seens a little unessecary, but its cool too. All of these things are great and it would be the perfect app for me to use on my school work.


The graphing function does not work.
I'm really disipointed,
I hate having to switch between tabs on my browser and the awkwardness of having to click on each of the seperate boxes on online Graphing calculators.
If you want just a regular scientific calculator app that looks nice, this is the perfect appfor you.
As for me, Ill just use my physical calculator for that.
Really, I only downloaded it for the graphing function.
I might have given this app three stars in spite of this, but the logo clearly has a misleading graph on it, and there is nothing in the decription saying that you woud need to pay to be able to GRAPH on a GRAPHING calculator.
I mean I get it, calculator app developers need to make a living too, but at least inforn your consumers.

Anyway main point is:

Developer Response ,

UPDATE: The bug has been fixed in the latest update v1.0.1. We would be happy if you can try the app again and update your review :)

Thanks for your feedback and reporting the issue regarding graphing. Graphing is free to use in Taculator but currently there is a bug that the equation doesn't get saved.
We are giving our best to fix it as soon as possible :)

In the meantime, here is a workaround to graph:
In Y= menu, enter your equation as usual. Then press the Arrow UP or DOWN key on the calculator keyboard. Then press GRAPH. Do not press GRAPH or ENTER after you entered the equation or it will be lost (because of the bug). We hope this helps until we fixed it.
Sorry for the inconvenience.
