As a college student majoring in mathematics, I often find myself in situations where I need to visualize complex equations. One of my favorite scenarios is during study groups. We frequently gather to tackle challenging problems, and having Graphing Calculator Plus (X84) on my tablet has been a game-changer. I can quickly input equations and show my peers how they behave graphically, which sparks discussions and deeper understanding.

I can see why people like it, but it is not user friendly. I have yet to get the graph feature to work. I love the black theme and how the buttons are wider so less miss clicks, but using it for my stats class has been an nightmare. I wish there was a free trial so I didn't waste money since using the app is cheaper than buying an actual TI 84 Plus. As a student, I don't really need throwing out money on apps that are not useful.





Very nice calculator, however, the arrow pad buttons are too small, which results in accidentally pressing "Clear" when navigating the cursor around equations. It's very frustrating to accidentally clear a long equation after spending time entering it in. Please add more padding to the up and down arrow buttons. Also, with new versions of Android, 3 button navigation now blocks the bottom row of buttons. This makes the calculator incredibly difficult to use.





Fantastic calculator! Just like a TI-84, except better! So far I've found a periodic chart of the elements, added commands that allow you to look up atomic properties from the normal calculator screen, like ability to control the graphing screen with touch, built-in conversions, several physical constants, everytime I turn it on I find something new. Great job, developers! I hope you add even more features.





I really believe this is by far the best calculator I have used so far. Beautiful u.i. along with the awesome quick access feature . The only criticism that I have is: 1: Copying typed equations into a clipboard and to be able to paste number values from the phone's native clip board would be a nice feature to have. 2: Automatically place negative numbers in parentheses when using exponents. 3: When scrolling through previous calculated entries, you end up with a very small window to enter new equations in with previous entries stacked on top of one another without the ability of resizing it back to it's original size. 4: Would be nice to have the history memory larger. Say from 25 to 100 entries. I am still gonna give this 5 stars because I really like the work you guys have done overall. Overall I am glad I paid for this and would gladly recommend to others. Great work on this developers!





This is a faithful TI-84 emulator and so far I have not run into any problems. A shortcoming is less than adequate documentation, no "about" to show version number, and no statement that it's trying to be a TI-84 vs 83,85 or whatever. 4.5 stars. If you want a graphing calculator on your phone, this is a good one. Add free once paid for.
