TI 84 Graphing Calculator

TI 84 Graphing Calculator


FIVE REASONS WHY YOU NEED THIS APP 1. Keyboard and command syntax similar to physical graphing calculators -> No need to learn a new calculator. 2. Powerful emulator like Wabbitemu Calculator -> No more waiting to graph functions compared to slow physical handhelds. 3. Enter fractions, equations or functions in the same way as you would write them on paper. 4. Never forget your calculator at home! It's always ready on your iPhone & iPad, and it weighs nothing. 5. Save more than 80% compared to the retail price of an actual calculator which is over $100. FULL GRAPHING CALCULATOR • Graph more than ten functions at once, each with a different color • Add Lines, Horizontals, Verticals, and Tangents to the graph • Use your finger or the arrow keys to trace the coordinates of your functions • Calculate the Zero, Minimum, Maximum, Intersection, and Derivative • Find integrals and color the area under the function • Set the X and Y coordinates of the graphing window; zoom in and out with your fingers ADVANCED SCIENTIFIC CALCULATOR • Enter calculations in natural textbook format • Includes all basic arithmetic (+, -, x, ÷, ^, ², √, π, …) • Use advanced functions like sin, cos, tan, e, ln, Σ, ... • Scroll your calculation history and modify existing calculations with one tab • Store and recall variables • Quadratic Equation Solver MATRIX CALCULATOR • Work with matrices the easy way -> store them or enter them directly on the calculator interface • Do basic matrix arithmetic operations like addition, subtraction, multiplication or power of a Matrix • Put the matrix into Reduced Row-Echelon Form and solve linear equation systems • Calculate the determinant, inversion or transpose the matrix STATISTICS AND LISTS • Use lists for all basic and trigonometric ​operations • Enter lists using the Statistics List Editor or use curly brackets on the main screen • NOTE: Some commands of List and Stat menu are currently under development TUTORIAL AND CATALOG • Easy to understand tutorial to get started • Full Catalog of all commands with syntax, example, and possible error messages • Tab on highlighted math terms to read on point definitions PERFECT FOR HIGH SCHOOL & COLLEGE STUDENTS • Recommended by teachers to use in math classes • Pre-Algebra, Algebra 1 & 2 • Pre-Calculus, Calculus • Permitted on SAT/ ACT/ AP (your phone might not be permitted, but you can use the app for homework and borrow an actual calculator from your school for the test)



  • Terrible... Waste of Money

    By #DaBears🐻
    This is a terrible calculator. DO NOT use this for statistics. This is not the same as the hand held calculator and the buttons are not the same. I thought this would actually help me out but it’s just a waste of 5 bucks.

  • A must have TI 84

    By johny.byb
    Works great! I was looking for a TI 84 calculator and boom here it is!! Same functions as the actual calculator. I’m very happy and it’s also way cheaper
  • Great TI-84 calculator

    By joshv.91.11.1
    I’ve downloaded this app because I needed a ti 84 calculator. The app is even better than the original calculator. The graphs are looking better and are way more precise. Also it had all the other functions I was looking for. I highly recommend this app if you need a ti 84 calculator. Update: Now the developers added the support of lists. I didn’t need lists so far but it is good to know that they still work on the app and add features. 👍
  • Terrible app

    By I HATE TI-84 app
    Horrible app. Glitchy and just horrrible
  • BAD

    By refiill
    Do not install just waste of money and doesn’t give all features an original TI-84 calculator gives
  • Not a TI-84

    By djg0011
    I am giving this app a 3 because it does have potential with the promised updates. I purchased this app because I wanted to write some TI Basic programs. No programming capability. The second thing that I tried was to enter a complex number and multiply that number by its complex conjugate. I could not find the "i". The mode button only sets the number of decimal places and degrees or radians. The graphing functions that I have tried worked. The font used to label the key needs to be larger and bold. A nice feature is that the alpha key clears the keys and only shows the alpha label for the keys.
  • The stat button doesn’t work

    By Gsgshgroifhsrcdkandidkcvjvhf
    Please fix this
  • Functions were unavailable

    By steel1steel1
    The functions that I’d like to use it for are not developed yet. This and the manual are useless for my statistics course.
  • Stat

    By Hi friends 41702
    The stat function still doesn’t work. Horrible app, go somewhere else for a graphing calculator app.
  • Sadly

    By burbuja50##
    Definitely needs improve thus app. Not enough for somebody who start to use it. Incomplete app
  • Total Garbage

    By whatadisappointgapp
    This calculator is no where close to the TI84, can’t even calculate std deviation for a simple data list. False advertising... I want a refund!
  • Don’t buy this

    By Nathan Eastwood
    I just got this app thinking to myself “Oh perfect! A TI-84 calculator app that is relatively cheap! Awesome!” No. It’s not. When I went to go on to stat, it said it was still in development. I just payed $5 for something incomplete. Don’t buy the pile of garbage. It’s not worth it.
  • No reset button

    By smokeybeck
    The calculator is very good, but unlike the actual machine. There is no reset button. Adding one of those would really make it much easier when the calculator breaks.
  • The list bottom don’t work

    By ethan755775
    I literally just bought the app so I could plot my points for homework and it doesn’t work
  • Unfinished trash heap

    By Diamondfroggaming
    Currently in Algebra II, needed this on short notice. Open it, right away, “STAT” is under development. IF YOU'RE GOING TO CHARGE $5 FOR THIS, MAKE IT FUNCTIONAL FIRST.
  • Crap

    By frickle frackle tickle tackle
    Paid for an app that doesn’t even work fully. When you hit stat it says wait until the next update and it’ll work, so I waited. I updated the app and it said the exact same thing, wait until the next update. The class I’m using this for uses stat quite often, vv inconvenient.
  • Garbage

    By Worst Calculator Ever
    No tables until future updates and I paid for this!!!! Bad bad bad
  • It’s ok

    By $$$SHYGUY1234$$$$
    Kinda missing the equal font

    By Sweetestcin
    When is the STAT button will start working I purchased this calculator for that reason
  • Scientist Practicing

    By BigBadDann
    This is not as advertised, not even close. I own a TI 84 and I can assure you that this bears no resemblance to it. The developer should be asked to leave this site
  • I just failed my physics quiz because of this app. DO NOT BUY.

    By Thesilverlight28
    I left my actual calculator in my dorm so I decided to buy this because it seemed legit. DEAD WRONG. It doesn’t do sin cos and tangent correctly. I just failed a quiz because this thing just decided not to work. I just wasted $5. Please don’t do the same.
  • Terrible

    Calculator is average, and it doesn’t go into negatives for the table function
  • Do not buy this

    By lwink01234
    I downloaded this app specifically for the stat function and to graph. Yet when I click the stat button, it says it will be added with the next update. So I just spent money on something I can’t even use. Do not buy this app.
  • Some of the functions aren’t available

    By Sirenebisous
    There is no point in downloading and purchasing this app if it isn’t fully complete. The functions I needed for class aren’t even going to be here in time for me to use it. A waste of my $10 honestly...
  • Math

    By emstet
    This app is totally worth it. In algebra 1 we are using this so much and Instead of getting the 120 dollar one I got this app and it is exactly like the real one. You should get it.
  • Not enough features

    By joshjohnson1234567891011
    Most of the stuff in need to do it says it will have in future updates
  • Manual

    By Tidekat
    There needs to be some kind of tutorial or manual to go along with this app
  • Under development

    By Snow5308
    The app works very well. However, there are some features that are still under development, but once these features are added the app will be fantastic.
  • DON’T BUY!!!!!

    By nia.t
    does anyone know of a way to get refunded on apps that lie about calculator functionality??? in the app description it says that it is ‘perfect for high school and college students’ and that it aids app-users with calculus (which is the lie). after PAYING for the app and trying to utilize it for my stats/calc college course, like the app claimed it was capable of, the calculator’s ‘stats’ and ‘vars’ button options NEEDED for the essential coursework for problem solving in statistics AND calculus, don’t even work. so i either want to find out how to get a full reimbursement, or im suing for false advertisement bc now i can’t do my homework. the whole point of Texas instrument GRAPHING CALCULATORS is to be able to graph unlike a scientific calculator can, which is another reason i also bought this app and another reason why i bought this one instead of using my satisfactory calculator app preinstalled on my phone. what a waste of money x
  • THE Worst, Save your money

    By amb 1993
    I bought it and then when I tried to use certain options it tells me it’s under construction, I immediately contacted customer service, still awaiting a response which I highly doubt I will get. Only rated 1 star to be able to send the review.
  • Tan, sin, cos

    By kingj48
    The arctan, arcsin, and arccos functions do not work correctly. Don’t buy.
  • Poor functionality

    By Budmc121
    You want TI 84 functionality? Your phone is more than capable of providing that, this app is not. Your phone has many, many, many times the processing, memory & graphics requirements needed to emulate a TI 84 calculator. So, why is this app a piece of junk? It appears to be a work in progress. In very slow progress. It doesn’t even approach the functionality of a TI 83 or 84 calculator. No statistics, NO PROGRAMMING! The entire point of this purchase was programming equations so I could quickly & easily plug in my variables & repeatedly get solutions. At the current level of functionality this app has, for my requirements, I could have just flipped my phone into landscape mode & used the native Apple calculator. It’s absurd that this app is priced above $3. To price it at $.99 would be a stretch. And that’s not even approaching why they just updated the look of the icon while the UI is still out of the Stone Age. They update the icon everyone sees to make it look more flashy & attractive (more worth what they’re charging for the app) while the graphics within the app look like something drawn up on MS DOS & the functionality is nowhere near the TI 84 their app is named after. There’s nothing wrong with starting somewhere on an app & releasing it in an attempt to fund the future of the app. But that should be made clear to those purchasing the app. And it should be priced based on current functionality, not on what the finished product might be in a year or two.
  • Confusing

    By タケア
    I don’t know how to solve derivatives, the stats button doesn’t work, no linear regression. Can only do minimal things that is useless for calculus
  • Don’t buy!!!

    By jbatsss
    I purchased this calculator to solve problems in my stats class and I can’t even use it because it’s still under “development”. How are you gonna sell this product when you can’t even use it? What a shame
  • Hard to use

    By 79968115jjdjvfrr seessddSgfjsv
    Doesn’t look anything like the android one. $4.99 was a waste.
  • Don’t waste your money

    By StephCFl
    I am a college student. I bought this app because on the day of my statistics exam I realized I had forgotten my actual TI-84. I didn’t have enough time to go back and get it. I go to take the test and the functions that I needed for my test didn’t work, said they’d be available with the next update. Before I bought the app it appeared to be a fully functional calculator. I’m just glad my professor let me use her calculator when I showed her that this app didn’t work!
  • It is missing some buttons

    By just playing some games
    There are some missing features that the in hand on has but the phone one doesn’t

    By makenasc
    Bought this for my statistics class and literally not one of the functions i’ve need for this class has been available on this app. don’t waste your money!!

    By Boycott Texas Intruments.
    I am currently a college student, and bought this app when I was heading to class and realized I left my actual TI-84 at home. I went to use the stat menu to access some key functions for my statistics class, and it told me the it was still under development. Why did they release an app for over 3$ if it’s not even complete?? Well, Texas Instruments holds a monopoly on graphing calculator and took down the previous completely working graphing calculator apps so you are forced to buy their actual calculators. It is absurd that my phone is more powerful than a laptop computer was 10 years ago, yet I am stuck paying the same price for a graphing calculator that is fully functional that I would have paid over a decade ago. There is no reason this app is not complete, besides the fact they want you to spend your money on this app, just to realize you are stuck lying over 75$ for a fully functional one. The app keeps saying the stat function menu and other ones not functioning will be added next update, but it never is. Do not purchase this app, and do not purchase an actual Texas instrument calculator if you do not have to. If you are needing it just for graphing, there are many other apps that do just the graphing aspect of a graphing calculator. It is a shame to admit that if you need to use certain functions you will be spending over 75$ for it.
