- Under development

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.

- DO NOT GET, NOT WORTH EVEN A PENNY

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.

- Almost great

When I first downloaded this app it was just like my TI-84 which I liked because I was already used to the button layout, but now things have changed with the recent updates. For example, when I want to enter a fraction, I used to be able to click math, right,up, then enter (D:n/d) but in the app it’s different which is annoying because I already have that muscle memorized. Also, one of the huge downsides is the lack of iPad integration. Especially since the page on the App Store only shows the app being used on an iPad, which makes one believe that this is tailored for the iPad. Sadly, that isn’t the case. I would really like to see landscape viewing as well as multitasking features (side by side viewing). Last thing, can I change the x values when pressing 2nd graph. I know on the TI-84 you can change this by pressing the + sign.

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

- This almost feels like stealing

I purchased this app for one of the courses I’m taking. It’s not in my field of study, so I didn’t want to spend a bunch of money on a fancy calculator I wouldn’t use after the semester is over. However, having this app is essentially the same as having nothing because the keys I need are “under development and will be in the next update”, but I’ve had this app for almost the whole spring semester, it has since updated, and still I have NEVER been able to actually get use out of it. So after this app almost screwed me over, I found “G.Calculator” and it works amazingly for the exact same price. Please don’t waste your money on this company’s empty promises. If it’s only halfway done developing, why did they put it in the App Store at all?

- Same as TI-84CE plus

I bought this app for my calculus class. I didn't want to spend \$100+ for a couple classes. The app works great. I'm my opinion it works better than the actual calculator. It graphs a lot faster than the actual calculator, in all fairness my IPhone is a lot more powerful than a calculator. I also had an issue with the calculator(on my part), and support got back to me within the hour and fixed it. I used this app for Calculus I and II with no problems. One of the best apps I ever bought.

- It’s a good calculator but without all the calculator parts

I was using this calculator because the price of a ti 84 plus calculator would have been 100\$ so this was a cheaper alternative. One of the reasons I bought this was for finding the roots and max. And min. Of functions, it does this exactly like a TI-84 would. The only problem is that it cannot graph a scatter plot or find an equation for that scatter plot. While it says that it will be out in in a new update, the reason I bought it was specifically for scatter plots and quadratic function graphing. All In all it is the closest calculator to the TI-84 and a cheaper alternative to the calculator minus the scatter plot.

- Not a TI-84

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.

- Not even usable for a precalculus class

I genuinely couldn’t even get it to fulfill the most basic functions I needed for my precalc class. When I used the fraction function, it wouldn’t allow me to continue adding if I used an exponent or another fraction it would just push me to the denominator and make it impossible for me to even close my parentheses in an attempt to make the problem coherent. I used it for about five minutes before I realized it was taking me way more time to suffer through than just using my basic phone calculator. If you’re like me and simply don’t have your graphing calculator on you, suffer on, or try to find a less horrible app.

- Great TI-84 calculator

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. 👍

- DON’T WASTE YOUR MONEY, IT NEEDS WORK

I bought this app package led to believe it was full featured. All I needed was the simple linear regression function for my sixth child’s High School Algebra class. After having bought five TI Graphing Calculators, only having each one of them leave as each child left home for college, I thought this app would be the way to go. It promised to be hot stuff! No such luck. As you would have it, the linear regression is not developed yet, but planned for a future update! What??? I never would have believed this app could be so bad! The cosmetics are ugly too! Looks like kindergarten graphics, nothing like the calculator. Wish I could get my money back!!! Don’t waste yours!!!

- Excellent app!!!

One idea I have for this app is if when you click the 2nd key, it changes all the buttons to be that option turn into the full key, instead of still being in the same spot in the corner! Other than that I’m excited for the statistics functions update to come out!!

- Not for statistics

Edit: 10-15...they promised to add the stats function on 10-15...its 10-15 and guess what?? No stats function. Do NOT buy this if you need it for statistics. The calculator works good enough for simple math and algebra. However, I purchased this specifically for statistics and supposedly that is “under development.” I basically wasted money on a calculator that does the same thing my real world calculator already does. And I didn’t get 50% off like it promised when I bought it. I spent the full 9.99. Waste of money.

- Not worth it! Important fxns under development

I downloaded this app for my Statistics class because I didn’t want to pay a ton of money to buy a calculator that I would only need for a semester. Unfortunately, the STATS function does not work and is still under development even though it was supposed to be updated on October 15th. There is no way to contact the app developer for a refund. I sent an email through App Support but I’ve not gotten a response. Download/purchase another graphing calculator app if you need a calculator for a Statistics class.

I bought this app for my college statistics class because I didn’t want to spend \$100 on a calculator I wouldn’t use after the semester. The calculator worked for some of the semester but then I started to realize that many of the functions that I needed weren’t even on the app! I’ve been having to rent calculators from the library and borrow from my peers just to complete homework assignments!! Waste of money, don’t purchase.

- Not happy

I got this app in hopes to have a great TI Calculator on my phone. I have the actual TI-84 Plus CE and I love it, but this app doesn’t have the same features. I read reviews where the developers responded and said there would be an update on October 15! It is currently October 16th and there is no update to be found that include the stat menu or anything like that. Hopefully you guys fix this and tell the truth about when you will have stuff. As of now this calculator is only as powerful as the one that comes on the phone :((

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!

- Not for a Stats class

Most of the app is great. However, I bought it for a Statistics class, and everything I need specifically for that is still “under development.” When you hit the star button it says it’ll be out in the next update, but I’ve updated 3 times and it’s still not there. If you want this for Statistics, don’t waste your money. If you need it just for simple algebra and graphing, go right ahead.

- User friendly.

I’m using this application from long time. It’s easy and very much cost-effective as compare to other apps. Full user friendly features with all useful description.

- Don’t purchase

I purchased this app in hope of using to work on my statistics class but one of the modes that I need is not working saying it will be available after the next update and that was about a month ago and I just recently updated it and it still says the same. Wonder if it will we be ready because it sure is starting to look like I got my money robbed.

- Several functions still under development

I bought this app in hopes that it could act as a replacement for buying an expensive calculator that I’d only need for one semester. Unfortunately many of the functions that I need to do my assignments are still under development. I read that they’ll be launching them soonish but it’s not soon enough to get my work in. Pretty disappointed with the situation overall.

- With the new updates this now does everything the real one does

With the new updates this now does everything the real one does

- Well rounded app

Compared to similar apps on the App Store, this is by far the best one. It is extremely user-friend, I would personally recommend this if you are needing a decent graphing calculator for your phone.

- Very well built

Barring the lack of statistics functions, this is a very well done calculator. One suggestion for the developers: enable split screen for iPad! This would really take the app to the next level for college students looking to use iPads. Great work!

- Question

Hello to the good people who are making this app I would like to know if there is currently a way to make your own programs or is that still in development

- Math

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.

- This application is better than other software emulators

I was searching for wabbitemu emulator which I found in this graphics application!

- Useful.

This is a really good thing that one can check the calculation history. I can solve some of the quadratic equation now with the help of this app and much more.

- Good for learning and teaching

My teacher recommends the ti 84 app and I found this app to be wonderful. Earlier I was having problem with determinant, inversion etc but this app vanish all problems.

- Thanks to the developers!!

Thanks to the developers. The concept of the ti84 app is really great. The other good thing is that it provides much content as compare to the real calculator.

- Matrices glitch

It works fine for the first set of matrices but when you try to edit the matrix, it reverts back to the original matrix that was plugged in before. It still shows you the edited matrix but it acts like it is the old matrix. I’m not sure how to fix this?

- Why is this missing functionality?

I got this hoping to be able to display to a class how to use the TI-84, only to find there is no Test menu. Can someone explain to me how to graph piece-wise defined functions without such a key??

- I love this app <3

I’m maths teacher and I recommend this Graphing Calculator to my students. It’s a really nice version of the TI-84 Plus CE which can help in solving problems of all different topics.

- Easy to use, great!

App is easy to use, contains all the user-friendly features and cover all the important topics.

- Great approach!!

I like TI 84 Graphing Calculator Pro application because in this you can write down the equation same as we can write on paper. Moreover, it includes all the basic arithmetic. Great approach!!

The \$4.99 is just for the manual. Then you have to pay more to get the calculator. However, the calculator is not fully functional. I tried to use a stats app only to discover it is still under development. I feel deceived and wish I had not purchased.

- No reset button

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.

- This is the best app for students!!!

I love the calculator, it’s accurate and is just like an \$80 graphing calculator but for 5 bucks!!! Download this app it’s worth the money!!!!

- Not Complete

This app is advertised as a fully developed app... it’s not. Especially frustrating when you need to use binomials, normalpdfs and poissonpdf for dristrubution and it’s not even available to use. All they do is give you a definition and example of what it is.

- Very Satisfied

I’m using this computational application to do my homework. Friends you should try this app once.

- Crap

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.

- It is missing some buttons

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

Seriously. Don’t do it. Especially if you’re a college student in a STATS class like me. They promised an update for October 15 that would have all the functions available and there was no update. Very disappointed with this company and I will never make the mistake of trusting them again.

- A must have TI 84

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 Calculator app

Best TI App I’ve used yet. Does everything I need it to! No need to buy an expensive calculator when I already have one here.

- Thanks!!

I was seeking for Math’s application which can solve all my problems. 5 stars from my side to the graphing calculator.

- Lovely!!!

This is a good thing that there is a tutorial. This helps a lot in understanding the ti84 calculator. I highly recommend this app to all Math’s lover.

- THE Worst, Save your money

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.

- Provide more than one regular computing application

TI 84 GCP is teaching everything in a good way. This app is providing more than my expectation.

- Missing many functionality!

Many functions shown in the preview are not available. I bought this app specifically for statistics, but all distribution functions are not available. The app is a lie. The preview screen you see doesn’t equal to what you get!

- A bit lame

It only has angles in radians, not in degrees. This is definitely bad for young students just learning trigonometry. A lot of formatting functionality is missing, so it is not really emulating the TI 84.

- I WANT MY MONEY BACK!

This calculator doesn’t go what it is made to do. Please refund my purchase as your app doesn’t work as you say it does! I will continue to leave these reviews!

- T4 calculator

This is a scam, first they charge you \$6.99 for manual and than they charge you another \$19.99. It still doesn’t have the stat option. Don’t get it because I regret getting it and it is useless for me.

- No STAT function

I bought this calculator FOR statistics. It’s promised to have a new version coming soon. For now it is useless to me.

- Great!

The only thing I would change is the actual buttons look boring. Make them look like a traditional TI-84 calculator.

- Some of the functions aren’t available

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...

- I just failed my physics quiz because of this app. DO NOT BUY.

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.

- Kinda bad but that not totally

It’s not letting me use the y=. And it just makes everything more inconvenient so yea still a great app in oppose to buying a 100\$ calculator

- Review

I don’t know how to use it tbh it’s steps are different than a real graphing calculator

- Terrible

Calculator is average, and it doesn’t go into negatives for the table function

- HELP- Missing Features

When I hit STAT, it should let me move to the right and enter a new tab, CALC, but it doesn’t. Any suggestions?

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.

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

- TI 84 Graphing Calculator Pro is the best

This great app having all the concept of Math’s. If someone wants to really understand the graphing calculation then this app is the best.

- Best calculator app

Wow!! I never saw such calculator app in which you can enter the calculation in the usual format. Thanks a lot!!

- Terrible

I had been recommended this by a teacher and I ended up paying for it twice because it wouldn’t let me access anything the first time. It also doesn’t do what I need it to do.

- Worked great first problem not after

I used the graphing calculator one time and it worked perfectly and great colorful graphs. I worked a second problem and the graph will not show up. It will not remove the “LEFT BOUND?” words. It will not even respond. I have cleared, closed the app, reopened. I’ve tried everything. It is a great concept the problem of not being consistent is a PROBLEM. PLEASE CORRECT THIS ISSUE. YOU HAVE AN AMAZING IDEA.

- Terrible... Waste of Money

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.

- Good idea :D

This app is supporting all the basic and advanced functions.

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.

- Great features

The features of TI 84 Cal are awesome. It contains all the basic operations with all the clear explanation.

- Tan-1 doesn’t work right

The tan, cos, and sin, and their inverses do not work right. I’m getting incorrect answers. I set it to degrees but I’m still getting incorrect answers.

I don’t know if you’ve realized but your calculator appears to calculate the inverse trig functions incorrectly.

- DO NOT PURCHASE

This calculator gives factually incorrect answers to what should be simple problems (sin/cosine). You should definitely purchase this if you want to get every problem wrong on your homework!

- Mr.

I never reviewed any appl, but I have to say something about this one. It is useless, and so many features in a TI-84 are missing. I would give it a zero star, if possible, a total piece of junk. Do not waste your money.

- Not enough features

Most of the stuff in need to do it says it will have in future updates

- Best app ever......

TI 84 Graphing Calculator Pro is the best quadratic equation solver. It’s a good way that we can enter the calculation as like textbook format.

- Great replacement for the ti84

Excellent app for school. The best affordable alternative for students.

- It’s decent

It’s good enough for my college algebra Class so...

- DO NOT BUY FOR STATS

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!!

- Ti-84

I was anticipating that this app would work so I could complete my assignment but instead it said I will have to wait for the next update! I just wasted 10 dollars for this stupid app! I want my refund now ! 😡😡😡😡

- Statistics option

I downloaded this app so that I would be able to use the statistical option and it was a waste of money and time because I can’t

- Worth great

I was looking for the ti 84 graphing calculator and found this app. It works perfekt!

- Ti 84 app for Apple

It is a very poor app. You cannot work statistic problems associates with linear regression. The app does not come with that feature. Also, you cannot do box plot graphs, scatter diagram and histograms. It is a waste of money.

- Give 5 stars for this app

In this app, I love advance Scientific Calculator and Matrix Calculator.

- Horrible

If I could undo the purchase I would. I needed it for statistics class and it can’t be used right now for that. Update coming soon. Very disappointed.

- Waste of money

Don’t waste your money. This doesn’t seem to do what I need it to do for statistics. The instructions in the manual seem straightforward, but it’s not working like expected.

- DO NOT GET THIS APP ITS STILL DEVELOPING

I spent 3\$ on a app that isnt even complete. Its been 3 months and I have yet to receive any updates on when it will be completed. Its calculations are very wrong at times. Please don't waste your money like me.

- Not the same as a normal graphing calculator

I would not recommend this calculator in the least. It is very different than a normal graphing calculator. I wish I hadn’t spent \$5 on this nearly useless app.

- Waste of money

Made me pay extra money just to not be able to use a calculator. Waste of my money, might as well buy a real calculator.

- Malfunction

Nothing on the calculator works. Whenever i try to access a function a message is displayed saying wait on the update.

Got this for my daughter on the fly and the functions she needed it for are under development. Don’t sell an app that does not work as its name suggests it should!

Attempted to use STAT/LIST/DISTR menu but received message it was unavailable until next update. And was not informed when next update would occur. Very disappointed!

- Not actually a ti 84

It has a lot of functions but is not a full ti 84 For example when put in degrees mode the answers to a trig function do not come out properly.

- Scam

Don’t buy it is all a scam and they make you buy other apps before you can actually get it to work and it is still bot good

- The list bottom don’t work

I literally just bought the app so I could plot my points for homework and it doesn’t work

- Enlarging the the graphing

How do I enlarge the screen?Presidently the graphing screen is not as large as a handheld T-84? I recommended this app but my students are not happy with this virtually T-84+.Help! Anthony Pulino

- Keeps crashing

I can’t enter any problem without the app crashing. Fix it.

- No use

I spent \$10 for a product that doesn’t even work. I bought it for STATS & It says it’s in the process of being made?!?! Scam!

- Confusing

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

- No statistics options

This app is deceptive. You can’t use it for stats. Half of the functionality is “under development.”

- Horrible

I was trying to use this for a stat class but now I realize the things I need it for hasn't been developed .

This is terrible for how much it is. One day it works, the next day it doesn’t. I wish I could get my money back.

- Not fully functional

Missing major operating components. When will full modes options and programs be editable?
