  • “Output(row,col,expr)” clears row first

    By AdmNel
    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!

    By lollygsgger
    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.
  • Perfect

    By Squidzzzzzzzzzzzz
    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

    By Joey8428
    Whenever 1 Var-Stats is used, an error occurs and cannot be calculated.
  • Syntax Error

    By Pokohstar
    Just bought it, and I guess it’s too complicated for me. Typed in -2(-3)^2+3(-3) “Syntax Error” Welp
  • Where was this 5 years ago?

    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

    By LoganW(:
    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!

    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

    By Jwink3101
    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.
  • Amazingly!!!

    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

    By mh032018
    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
  • Good

    By Matteo Supreme
    Good app
  • awesome!

    By annf24
    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

    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

    By Arshad1
    Good overall, but could make some of the UI elements more consistent
  • The best calculator app

    By Plasticin
    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

    By IBM360 Model 50
    Still learning how to use it, but it works great!!!
  • Programs

    By Carewsssssss
    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

    By GooseHonkMan20
    As long as you spend 5 bucks on this app, it works really well!Just like a TI-84 calculator
  • Best app ever!

    By Catattack13
    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!
  • Solver

    By Teacher math and programming
    It doesn’t work like the regular TI 84.
  • Best I’ve Found On iOS

    By expensive_news
    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

    By Scientistevan
    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

    By xPaiigex
    I don’t understand how to use half of this then the normal calculator
  • App is Dope!

    By Danny-456
    (Engineer) I use this app a lot! Only thing I ask is to make the APP Icon look dope to match its dopeness.
  • Godlike

    By Percy Hictate
  • bad!

    By PicklesUWuv
    It’s really poopy and I want a refund because it called me vegan.
  • Lacks statistical plotting functionality

    By pyzkmuzk
    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

    By bbygoose
    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

    By Jozzzzzzz
    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

    By braddf
    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

    By Angelia2017
  • wow disappointed

    By charleysept
    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.
  • Amazing app!!!

    By FarxSparkle
    OMG This app is a blessing I don’t have to spend $100 for a TI-84 this is $5 and it does everything!!!!!
  • It does work very good, but...

    By Freckled Panda
    In class I’m doing Average Rate of Change and when I click on the 2nd to last step to get my answer, the last step won’t pop up. It goes like this. I go to STAT, EDIT, enter my data in the columns, then click STAT again, go over to CALC, click choice 4, and then after choice four you’re supposed to have 5 different options, and the last one is supposed to be calculate, I can’t seem to find that and I feel like the answers I’m getting are wrong. Is this feature on the calculator? Am I just missing it?
  • It sucked

    By rylee916
    It doesn’t work one bit
  • No manual +

    By JC10160
    There is no manual. No = to write equation. No solve for variable options
  • G.calculator

    By gemenis1123
    En muy buena te ayuda en todo lo que sea de álgebra, geometría, trigonometría y mas.
  • Logs and multiplying exponents

    By dbsjkaskd
    The log is right but also not cause when you do log(value) there is supposed to be a slot after log and before the value (for example) log4(16) and also when you are SQUARE rooting negative numbers you are still getting a negative even though it’s supposed to be positive (for example) -6^2 is giving me -36 when I should be getting 36
  • Glad I bought it

    By Austin vH
    I was skeptical at first, since I didn't want to waste 5 bucks on an app that didn't work right. However, this works just like a TI-84. I wish I could use it on tests, since it can do some functions my TI-83 can't. I prefer it over my actual calculator, and it's well worth the money.
  • Failed first use

    By Wolfcri
    The first thing I did was check Inverse tangent of 1 to validate the calculator... wrong. What is this good for?
  • Graphing calculator

    By 2379
    The app is great cheaper then purchasing a real calculator!
  • Amazing

    By WonderfulChris
    This is by far the best calculator on the App Store. Worth the price, and I love how the buttons are positioned identically to those that we have used very often. *cough cough* T.I. I would only suggest that, if possible, they increase the vibration sensitivity since I don’t really feel the vibration when I’m typing against he table. Great app 👍🏼
  • Best of its kind

    By Hiko303
    I’ve been a TI Calc fan back to the SR-50 of the mid 70’s, and this mostly faithful rendering (with tons of enhancements) of the TI 84 is the top one on IOS. Works smoothly, and the developer releases frequent updates. Hope the graphical plotting functions get a bit more attention, but overall I would recommend this highly to anyone.
  • Feature missing

    By Ayad E. Korial
    We need solve (( infinite )) integral feature in this app only (( finite )) integral solve
  • Great App!

    By jrhea815
    It functions just like a graphing calculator and it is super convenient since it is on my phone. I’m being kind with giving 5 stars but I’d put 4.9 stars if I could because this app doesn’t have the ability to add/subtract/multiply/divide lists within the edit tab. Otherwise this is a great app!
  • Graphing Calculator Plus Review

    By Dr. Albert Einstein
    Just like a TI-84 Plus CE!
  • Pretty good

    By Salmon Selman
    Graph is confusing and hard to navigate
  • Bugs

    By TonyTheAssasin
    Yes, the app is very useful and convenient. Except for the fact that sometimes when you use specific functions etc, there would be bugs in which the answer would be invalid or incorrect. If that bug is fixed, this app would definitely be five star worthy.
