Buttons don’t respond sometimes
It’s like having the real thing ! 5/5
It saved me in a crunch.
I broke my calculator by accident on test day. This helped.
Not Satisfied 1/5
I am not satisfied with my purchase and I would like a refund as soon as possible
Not a fan 2/5
This is just too confusing, and not like the TI graphing calculator that I used. Currently I’m using the calculator for calculus, and the graphing is very frustrating. There also doesn’t seem to be a good manual available to understand the calculator better. I feel like I wasted my money. This is also not optimized for an iPad.

Good need this instead of buying it
Delete key is broken 3/5
Del key doesn’t function at all
it’s a great calculator! just like the texas school calculator!
Delete Button Not Working 4/5
For some reason the delete button on the calculator is not working.
It’s quite annoying please fix!
Please help!!! 4/5
I need to know how to find the minimum and maximum points on a graph from a quadratic equation. When I go into graph and hit calc, I don’t see what I usually see on my ti84plus.
Doesn’t do basic root finding 1/5
By Level up!!
I’m in college algebra and I have to find zeros, or roots all the time, this app for one doesn’t make it finding those very easy. So until they can implement a way to just find zeros or an intersect button like the TI-84 does, which I guess this app is supposed to replicate but can’t do something as simple as that. One star not worth the money, if it were possible I would give 0 stars
A well developed app 5/5
I enjoyed the user friendly approach and familiar lay out I am use to. Great adoration to the apps on my phone
Best Graphing Calculator Ever 5/5
By Sean Xavier
I had my students download this app and saved most of them $150. It’s truly amazing!!!!
Good calculus 5/5
It’s really useful for high school calculus; further testing is required for other courses. Pro tip: using the trace tool will let you finds zeros extrema etc
How to start. 1/5
I bought this app and there is no way to learn how to use it. The web site says it comes with tutorial video, but I have not found it. There is a manual that gives guides to expressions but no information as to how to put them together. It talks about programs but no info as to how to do them.
It’s gay 5/5
It is gay jk love if
“Output(row,col,expr)” clears row first 1/5
Multiple calls to the Output statement having the same row value will only show the last Output statement since each call seemingly clears the entire row before writing its expression at the given column. This is not how the calculator works, and makes my purchase worthless.
This is great! 5/5
Listen, I’ve used a lot of calculators, I’m have a bachelors degree in math, and there is no better graphing calculator then this one.
I was so stressed that I had forgotten to bring my actual calculator home but this literally has everything I need. I can graph and make tables, as well as find specific points/ intercepts on graphs (of parabolas and whatnot) easily because it has the same interface as the calculator I’m used to.
1 Var-Stats can not be use 3/5
Whenever 1 Var-Stats is used, an error occurs and cannot be calculated.
Syntax Error 1/5
Just bought it, and I guess it’s too complicated for me.
Typed in -2(-3)^2+3(-3)
Where was this 5 years ago? 5/5
By Ben Mackowski
I've been looking for a TI-83 simulator for years. I wish I had this back in college, rather than carrying around an enormous graphing calculator from the 90s. Mind you, they wouldn't have let me bring an iPhone into the tests, but the point stands.
Weak on graphing options 3/5
I bought this calculator for a stats class and we are required to graph box plots for most of our problems. I was really hoping that this app would come with that feature.
Great Calculator for Students! 5/5
By Moonwink Cuber YouTube
At my school we use the ti84 and it’s great to have the exact same interface with me without having to pay for the big clunky thing! A lot of reviews say that it got sine or tangent wrong but that is purely user error. These users are forgetting to set it to degree mode 😂. Easy investment that you should consider!
Great calculator but could use the medium better 4/5
I’ve been looking for a good calculator that evaluates expressions as they are shown. For example, with the otherwise-amazing PCalc, if you want to compute “sin(45)” (in deg mode) you type “45” then “sin”. In this app, it is how it *should* be! You write the expression you want and it calculates that!!!
However, it is a graphing calculator to a fault. It doesn’t take advantage of the fact that it is an app and maintains the graphing calculator interface. Menus are hard to find, typing (while thankfully on a real keyboard) is one character at a time, and navigation is as clunky as on the real thing. Also, once I hit “Y=“ I cannot, for the life of me, figure out how to get out.
And if I wanted to program in it, I’d probably find some different apps to do it better. Same for plotting (where I’d use Pythonista to do it there).
So, overall, it serves its purpose...almost too well. But if you’re looking for as-close-as-possible to the bona fide graphing calculator, this is it! Or if you’re just like me and want a traditional calculator expression evaluation.
By Back to School Student
This is literally a life saver. Everything is exactly how it is on an actual TI 84!! Props to the creators. So useful to have this on me all the time for my class and this only costs $5 instead of $80!! Hands down best app ever. The only thing I wish this would do is give you a vibration or a taptic feed back when you hit the buttons, but that’s literally just me being anal.
You have to hit 2nd every time instead of long pressing 2/5
It would be nice to have long pressing as a feature. I hate having to hit 2nd all the time especially for inverse trig functions which I use a lot. Just add long pressing
By Matteo Supreme
I am a high school student and we use TI-84 calculators in class but they are very expensive so I can’t afford to have one at home. This does everything the TI-84 calculator can do and it’s a fraction of the cost.
Programs don’t work 3/5
By king garfielf
This is honestly a great calculator simulation. It has good pricing and works well. But one time I tried to write a program. I wrote just 5 lines of code and all of it was correctly done. But then I got error messages (datatype, syntax, etc). I checked what I did and it was all correct. I even checked my program on my actual physical Ti 84 plus and it worked like it should. Please fix this problem.
Good overall 5/5
Good overall, but could make some of the UI elements more consistent
The best calculator app 5/5
True to the TI84. Love that we can pin functions permanently on the top bar. I would really like a backspace key however. I know this is not present in that original 84 and the dev wants to stay true to that but perhaps a setting to change the del key to a backspace key would be nice
Still Learning How 5/5
By IBM360 Model 50
Still learning how to use it, but it works great!!!
This app works great for a calculator but the program feature does not. I had a program on my TI-84 CE that I put on the app and it will not display my answer, instead it just says “done.” The only programs I am able to make work are the ones that the app comes with
Just like the TI-84 5/5
As long as you spend 5 bucks on this app, it works really well!Just like a TI-84 calculator
Best app ever! 5/5
Why spend $100 on a graphing calculator when you can get this app!! It is nearly identical to the one I use in school, the functions are the same and the buttons are in the same places. This is a high quality app for a great price, and I definitely recommend!
By Teacher math and programming
It doesn’t work like the regular TI 84.
Best I’ve Found On iOS 4/5
This is a really good calculator app, the best I’ve found on iOS. It works almost exactly like the TI 84.
My biggest problem with it is that the Del button deletes the thing in front of the cursor, not behind it, like it does on the calculator. And while I think it might benefit the UI to make it look more like a physical calculator, there are notable improvements/ differences that the developers made to this app, like the graphing screen and when typing letters, with mixed success.
In the end while I would still prefer a direct emulator like Wabbitemu on Android, this is the best calculator app I’ve found on iOS.
Good app 4/5
Very good app. Similar to ti-84. I would recommend adding a way to access calculations like intersects and Max and mins. I have desmos when I want to figure that out.
Calculate usage 4/5
I don’t understand how to use half of this then the normal calculator
App is Dope! 5/5
(Engineer) I use this app a lot! Only thing I ask is to make the APP Icon look dope to match its dopeness.
By Percy Hictate
It’s really poopy and I want a refund because it called me vegan.
Lacks statistical plotting functionality 4/5
This is a very worthwhile app that does ALMOST everything the TI 84 does. However, it lacks statistical plotting functionality (or the functionality is broken). For instance, it cannot produce an accurate histogram based on a list of data. If this is fixed, I’d give this app a 5 out of 5
Liked it at first 2/5
I liked it at first until it started giving me errors and calculating incorrectly. I compared my answers to another calculator and they were wrong. I was using the stat 1-var. Now I’m upset that I paid money for this.
One of my Top 5 apps 5/5
I really love this app and I buy this app for people who I know would use it all the time. The developer(s) deserve all the praise and business they can get. Thanks for making this.
Wrong calculations 1/5
Paid 5 dollars for the app, first problem I used it for was to take the sine of 45. Gives me the wrong answer every time. Waste of money.
Saved so much money 5/5
wow disappointed 1/5
so ur really telling me that i paid 5 dollars of my hard earned money on this and it doesnt even have a stemplot, trace, or zoom feature. honestly useless for ap statistics.. just get a real texas instruments graphing calculator even if its the cheaper one and skip this thing if youre actually trying to get work done.
