Enjoy a lot of new functions and commands with this big update.

+ Taculator now supports different history tabs for your calculations. To add a new history tab, scroll down on the home menu and click on the "+" icon. This creates a new history tab. This feature is great if you work on different math problems at the same time or want to save your recent calculations but start with a fresh screen.

+ Tab and hold any button to access the second function behind it. For example, if you want to use sin-1 you can press "shift" -> "sin" or now just press and hold on "sin" until you see that shift commands are highlighted.

+ With this update you export your graph window as an image or PDF and share it with your friends or save it for yourself. Press the "graph" button and you will see a new little icon on the right. You can also save or share a full-screen graph.

+ iPad users are now able to enjoy Taculator in landscape mode and use multitasking with split-screen. This enables you to use your calculator together with another app.

Furthermore, here's the detailed list of new calculator commands.
+ Draw circles with specified radius and x- and y-value.
+ Seconds " button now available. Press the Shift button and "+" button to use it.
+ New Angle commands to convert coordinates from Polar to Cartesian coordinates and vice versa: R►Pr(, R►Pθ(, P►Rx(, P►Ry(
+ New Matrix commands: Fill( (fill a list or matrix with numbers) and randM (generate a random number matrix).
+ A ton of new statistical tests: 2-SampZTest, 2-SampTTest, 1-PropZTest, 2-PropZTest, 2-SampZInt, 2-SampTInt, 1-PropZInt.

+ New regressions added to STATS menu: LnReg, PwrReg, Logistic, SinReg.
+ geometpdf and geometcdf added to the Distribution menu.

My homework requires me to use a graphing calculator. This one is perfect. It’s just like the one I use in algebra. I’m not confused about the alpha function button because every part is a different color. It’s also helping me learn about the buttons on a graphing calculator, since it’s very hard in class. It’s also not one of those apps that makes everything pro (in my opinion) very helpful

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 wish the description listed which functions were for the PRO version

Pretty similar to TI-84 CE, but needs to enumerate clearly what features are PRO exclusive and which ones aren’t. For the price of $0 compared to its 150 dollar counterpart, I’d say it’s pretty good. Sadly, haven’t been able to do much statistics on here (regression, test values). It can graph, but it can’t do calculus or find max. It’s also missing an equation solver (but has a quadratic equation solver). Actually now that I think about it it can pretty much only graph and do the same things the built in calculator can. But still a decent value compared to the 150$. Plus since you already carry your phone around, it’s not bad.
