Darth Lightning - So much to love for a good price. 5/5! It is a must buy.
A couple of days ago I was struggling to complete homework for Math and when I had to work around it, my dad offered to buy this for me. I thanked him a ton and to this day, and hopefully for the rest of my life, I will cherish having this and be thankful this exists. It has all of the functions a graphing calculator has including converting a decimal of any kind to a fraction if possible, and a ton more things. I would recommend it to anybody who desperately needs a calculator for homework or work and it’s only 5 dollars and you will not regret buying this app.
Jwink3101 - Great calculator but could use the medium better
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.
Nguyen Texas - This app works exactly as Ti-84 plus CE.
I am looking for this app for years. Now the search is over. This app worth every single penny and now I don’t have to put the big graphing calculator in my pocket or backpack anymore.
Currently, I am using this app for Calculus III and other math classes and it works great. I am double check results between this app and my Ti-84 plus CE and so far everything are the same.
I hope developers put an option to let the DEL button works like the delete or backspace buttons on Mac/pc keyboards. Add more skins, APPS.
G.Newt - Matrix math in decimal form!
My car requires a 30% ethanol mixture to perform correctly. I quickly surmised that this would be a system of equations problem, easily solvable using reduced row echelon form via matrices. After measuring the ethanol content, I can plug in the numbers in decimal form and have the results of how much regular gas and E85 to put in in decimal form as well. I no longer have to carry my TI-84 with me to the gas station!
Freckled Panda - It does work very good, but...
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
QA.Pro - The best calculator!!!
This is actually what I need. It does everything. From equation solving to graphing and even units conversion.
I also strongly recommend this app for general calculations with history section.
Plus, the statistics features is very useful in case you want the sum things up to find mean or total.
Last, this definitely a must have calculator if you’re a student or engineer.
BIG thanks to developers!!!
Coolninja0033 - Decent for what I need
I’m a student in school and have been looking for a graphing calculator similar to the ones in school. I stumble upon this and pay and it works just fine. The menus like when you do 2nd y= is very hard to track but everything else is ok. I would recommend this. However I would like an *EASY* way to back out of the y= area as of right now I don’t think there is so I have to close and reopen the application.
dbsjkaskd - Logs and multiplying exponents
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
randomblock1 - Great, but one major flaw
This thing is great. It’s almost exactly like the real calculator. But I have 1 complaint.
The delete key works the wrong way compared to the actual calculator. The real one deletes to the left of the cursor, and this app only deletes to the right of the cursor. It’s VERY VERY hard to get used to, especially when you use the real thing often. It would be great to have a toggle to change the direction. Add that and you get 5 stars.
Back to School Student - Amazingly!!!
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.
Coolkid2461 - Great.
This app is an exact copy of the Ti-84. This app is worth the money because I would not want to buy a $150+ calculator when there is an app for it. It really helps when I need a graphing calculator for my math homework so I don’t have to use the school’s calculator and risk being fined for small damages. If only my teacher allowed me to use this app in class.
poor mathematician - Technical issue
When I get this scientific calculator app for free at the App Store. I wasn’t able to do much with, like graphing, Regression functions etc. it was asking for an upgrade in order to use it. I end up paying to get access otherwise it has no use for me.
How ever when ever I press for an answer an error message pop on the screen consistently.
I must close that for me to proceed to see the answer. This is not right at all. I mean what can I do?
Matthew A. Music - Great Calculator for Students!
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!
WonderfulChris - Amazing
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 👍🏼
Hiko303 - Best of its kind
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.
Austin vH - Glad I bought it
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.
IzNaz725 - Premium was worth it but....
Overall this is close as it can get to an actual graphing calculator but, Is there a way to get more apps in the calculator? Currently there is a few in there but the UI looks like it can fit more apps in there and to make the calculator more useful, more apps should be added for the user's choosing. Love the app saved me every time I can't find my real graphing calculator 😂😂😂 keep up the good work!!!
jrhea815 - Great App!
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!
i_am_dante13 - Horrible at graphing
I would love to give this calculator a higher rating but the graphing kills me. I have done everything possible but it just makes it impossible to graph. After putting in points, I can’t access them anymore. It is really frustrating. I’ve not even used the calculator for long and I’m already frustrated. Only God knows how much more frustrating it’ll get
Squidzzzzzzzzzzzz - Perfect
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.
Catattack13 - Best app ever!
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!
Ben Mackowski - Where was this 5 years ago?
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.
TonyTheAssasin - Bugs
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.
Plasticin - The best calculator app
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
Minty111213 - Great Calculator
I love it! It is just like using my Ti-84, but all I would do is add some more skins; kind of like how the Ti-84 Plus CEs have several different color options, maybe add some of those (or similar ones) here? Just a tiny thing, without that, it’s definitely still worth the 5 stars!
pyzkmuzk - Lacks statistical plotting functionality
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
wat did diddy do? - Updated Icon? Great App! Amazing functionality! Download!
This is an amazing app with amazing functionality and help. UI Looks great on IOS 13, but can we get an updated icon? I’d love to display it loud and proud on my default home screen and the current icon looks like a 1st gen iPhone app icon.
Achu1234 - Good calculator app but not giving correct results
I tried to do y=x^2 and y=2x+3 graph it shows x^2 and y=x graph always doesn’t mater what I change. It might be a bug, I tried this with real ti-84ce it plots good. Don’t know how to trust other values if it fails for simple plot.
I don't need a name - Graphing issues
When graphing an inequality such as Y=(0
the original stephen - Problems
I got the App. When I tried to use Solver, it indicated I needed the upgraded professional edition. I bought it. However, after bought it and getting the OPEN button, it won’t open. I have looked at it and after more than 20 minutes, it is still saying waiting as it is “loading”.
Cody Raper - Awesome App
This is by far my favorite calculator app. It functions exactly like the TI-84!
My only piece of feedback. I wish the haptic buttons would work on depress as well as release. Or perhaps on press instead of release. But, it’s not worth taking a star away.
takethisworldgivemejesus - Incorrect P-Values
I got this to try to do some of my statistics homework. I’m in the last week of class and was having difficulty figuring out p-values for goodness-of-fit tests, and this happens to be one of the last classes I need to get my Bachelor’s. This gave the incorrect p-value for every data set I entered. I ended up figuring out how to use excel instead. I would not recommend this for more advanced stat functions. Good thing I figured it out on excel before the final exam!
becaal - Val
This calculator app is awesome!! Takes hours and total frustration out of my homework, wish we were allowed to use calculators when I was in high school! Well worth the 5 to download the pro one! Amazing tool.
Jozzzzzzz - One of my Top 5 apps
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.
Level up!! - Doesn’t do basic root finding
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
frank samona - TI 84+ app
I am a math teacher and think that the app is very nice. Couple of thinks I am having problem with, I am having hard time in the mode to change to two decimals only, second is, under the TVM solver I cannot change the PMT from END to BEGIN. Any ideas?
rilouey - I’m Very Satisfied
Absolutely amazing. I was freaking out because I don’t have a TI graphing calculator but then I found this, and only for $5! It works just like a TI-84. I was very familiar with everything on it. Very thankful for this. Worth the $5.
bryce1226 - Annoying advertising
I love the app but I don’t like the advertisements at the top bar when am trying to solve a problem. I bought the app don’t want to keep hitting upgrade just to get rid of them.
Matthew Kyle Smith - Revolutionized My Productivity.
Can’t even begin to share the happiness that this app has brought me. The only thing i ask is that the app icon be updated to something super sleek or something. THANK YOU!!!!
PeterWhy25 - Only Good TI-84 Replacement App
This app has replaced the need for a physical TI-84 that costs a lot more. Although the button locations are somewhat different from the actually TI-84, all of the functions (as far as I can tell) are there.
CelticEddieL - We need the equation solver app
Great app and the new chemistry app is fine but you are ignoring the most important one on TI-84 calculators. Please make the polynomial/simultaneous equations app available in the near future. Other than that a great app!
Carewsssssss - Programs
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
annf24 - awesome!
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.
zungz1 - It’s actually a calculator
So I saw a lot of fake apps that say it’s a calculator but it’s not. I read through all the reviews and this one seemed to be good. I left my calculator at school so I got this for hw. Not bad. Too bad it ain’t free
Jonny Faz - Great!
Great app and very user friendly. I didn’t want to have to spend $100+ on a TI-84 calculator and this $5 app is perfect for my College Algebra class - and it has saved me at least $95!!! I’m very satisfied with it!
linear_circle - Disappointing
Solve function doesn’t work as I thought. That was the main reason I bought this. I’m used to the TI-89 which I didn’t know the function “solve(“ is much more advanced on. It can actually solve an equation for a variable. Not just plug in number to an equation.
Andrea Krom - Excellent Calculator!
I would suggest only one thing, I would change the delete button so it works more like how it is on the actual calculator.
MACANCHE - Delete Button Not Working
For some reason the delete button on the calculator is not working.
It’s quite annoying please fix!
Rambo8649 - Not a fan
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.
ManceRayder - Very difficult to use and cannot handle basic algebraic applications
I spent hours trying to figure out how to perform the most basic algebraic functions. I am unable to determine how to even input variables. The catalog was no help. Not recommended. Also note that Apple will not refund your money on this app even though it does not work properly.

Peut-être une suggestion d’amelioration, permettre d’afficher plus grand. Sinon c’est un outil puissant.
Reviewer_apps - Some functions don’t work
This calculator gave me the wrong answers when I tried finding the area below a curve so that was when I used the functions sum(seq(...). It worked for smaller values but once I’d use it for values like 50+ it’d just be wrong. When I bought an actual graphing calculator and used the same functions I made sure I plugged in the same values as I did for this app and winded up getting the right answer on my calculator. A minor thing that I’m sure can be fixed.
mathreviewsprincton - Review
This app sucks
Trizzzle21 - Worth the cash
Instead of buying a $100 calculator, I got this beast of a calculator for nothing. Does the same thing as expensive calculator.
Nsgddhdhzjdd - Disregard my last review
This works great and has done everything I need it to. X and y intercepts as well as the vertex can be found by tapping the points on the graph.
lblmj1996 - So happy to find this!
I was very happy to be able to buy this app instead of purchasing a $200+ calculator. But in trying to use the sigma Int function, it so far isn’t working. How can I fix it?
Mahiru&Zen - A little help, please
Hello I’m new to using this calc. I’m wondering how do I graph my stat plot and how do I zoom in and out of the graph???!
Kevorkazito - Nice job.
This is an excellent calculator.
tchitchi1983 - Un ordinateur
Ce programe me rapelle ma TI-83 sur l.aquelle j’ai appris a programmer en basic. J’adore ce programe de la Ti-84 qui me permetterais aussi de faire des programe basic interne. Ce programme remplace, en quelques sorte, la calculatrice...
Tony Xi Chen - It is great!
PLEASE update the GUI of infinity calculator. That app deserves to be as cool as this one.

emmyboss94 - Cal
I started a stats class in college and graphing calculator Is required, I was so downed because the ti-84 was very expensive and I couldn’t afford it at the time, then I found this app.. Simply the best!
hackworks - Perfect reproduction of real calculator
Nice to have something very similar to a real calculator. Helps improve muscle memory and seamlessly transition between the two.
A feature request:
Increase the display area font size (not buttons) for my old and tired eyes.
Calculator text in the icon could be removed. Darker icon will make it look better on screen.
Chalkjockey - Share function doesn’t work. Critical!
I purchased this version to support my online teaching efforts as our school has adopted a distance learning model with the COVID19 virus pandemic. Unfortunately, EVERY time is tap on “Share” in the graph display, the app crashes. I’m on an iPad Pro with the latest version of iOS. I hope this bug can be sorted quickly.
LoganW(: - Weak on graphing options
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.
grimtoothy - Good with errors
Product is fairly good, but does appear to have bugs. For example the rowreduce command on a 4x3 matrix crashes with a wrong dim error. But this was also a problem with the old ti-83 calculator
DrewLife365 - Love but Graphing window could use some work
I love this app it works exactly like the ti 84 but with a touchscreen but the only problem is that I can’t change the scale in the window tab while creating a histogram. That’s a huge downer for me.
Wrangler1945 - How to start.
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.
The King's Nomms - Satisfactory
It has all the features of a ti83 and much more and it’s totally free. What more could you ask for?
n0t3v3n4pers0n - Good calculus
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
Rasheed Johnson - Hands Down Best There Is
I’ve gone out of the way to write a review; not to mention, first ever review. This calculator is the best things to ever grace cellular phone tools...
Carly Preuss - Binomial incorrect answers
The calculator was working fine until I wanted the correct answer for binomial work ( pdf & Cdf)
Then I was getting the wrong answers. Needed help and am looking forward to hearing from the developer hopefully soon!
Will be downloading another app to help ASAP.
Then since I was rating this app 1 Star, it wouldn’t let me post it
meno1 - Great but needs 1 more feature
This is most likely the best calculator on iOS. But it needs the ability to paste into the app. Add that, tell me about it and you get 5 stars.
ed__gar - Saved me a lot of money
Great especially since professors let me use it in class
Cubsfanadam - Can’t simplify some algebraic expressions
Comes up with a syntax error when trying to solve/simplifying algebraic expressions. I can enter it exactly as it is on paper and it can’t solve it. For $5 I expected better.
It'ssss meeeee@103728 - It’s wonderful
This calculator app was absolutely stunning. The only reason it does not get five stars is because I had to pay five bucks.
Bitmapixel11 - Please help!!!
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.
J/921 - Good app
Very good quality app and inexpensive! Recommend buying! It’s worth it to save yourself from buying the $100 Ti-84 plus!
isaacgrim2019 - BEST APP EVER
For the price it’s well worth it because some calculators can cost up to $200 so well worth the 5 dollars in my book
Tellis36 - It’s like having the real thing !
It saved me in a crunch.
I broke my calculator by accident on test day. This helped.
mh032018 - You have to hit 2nd every time instead of long pressing
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
BalthazarWoll - A well developed app
I enjoyed the user friendly approach and familiar lay out I am use to. Great adoration to the apps on my phone
Lehrer1 - Works as a calculator
This app works as a calculator. A skin that looks like the real calculator would be a nice option. Also, stop bugging me about a review!!! It’s an annoying pop up when I’m in the middle of a lesson. Especially since I’ve paid for the app.
kachoo_ - Great for college!
Needed a ti 84 for college, and found this app! Much cheaper to buy this $5 app than the $100 calculator. Works great with iPadOS multitasking, and fully emulates theta 84
Arshad1 - Good overall
Good overall, but could make some of the UI elements more consistent
mudge365 - Great, no delete button 😭
Great app, not worth the $$. Could be cheaper. Graph looks great, but it’s impossible to navigate.
ErMerGerdd - Disappointed
I only got this app because I needed to use the list function
Unfortunately, the only function I needed, wasn’t available in the app
(L2 = L1 - 3) something like that
Very disappointed considering I just spent money on this app
JasonHaFi - Excellent alternative to TI emulators
This calculator is very similar to the TI-84. It is very user friendly and has an intuitive user interface.
bangbang101600 - Don’t like it
I downloaded this app to use it for my math class. I tried to use normal cdf and an error sign popped up, I tried to use different way to do it but the error still popped up. I’m very mad about this because I had homework due today and I can’t do it with out that.
Scientistevan - Good app
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.
Sean Xavier - Best Graphing Calculator Ever
I had my students download this app and saved most of them $150. It’s truly amazing!!!!
bbygoose - Liked it at first
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.
lollygsgger - This is great!
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.
Wolfcri - Failed first use
The first thing I did was check Inverse tangent of 1 to validate the calculator... wrong. What is this good for?
billb69 - Command entries
It can be hard to enter detail command and of you make a mistake the clear button makes you start all over
AdmNel - “Output(row,col,expr)” clears row first
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.
Stullesha11111 - Great back up calculator!!
Bought this app because a row of buttons on my Ti84 calculator stop working, so i got this to pick up the slack and it's absolutely amazing.
hezhexjenxekx - .
Need directions and how to get to certain functions. Specifically, how to delete and how to get to the second function on each key.
Where are you going? - This app
I like this app! In algebra class, my teacher, Mr. Shoemaker, explained about it, and I got my mom to buy it on my iPad and this iPhone!
Sethrobe - Zoom
This app is great except it needs the zoom key to help with graphing especially zoom fit
IronAckbar - Calculator works well
It runs as expected
Montzzz13131313 - Great App!
I have been wanting this app for over 4 years now. So convenient!
yanxiaoci333 - Hope it can den supply Chinese 🤔
I love this app after using some part of it's functions.
But sometimes it's too difficult for me to read bunch of English words.
Hope you guys can make it support Chinese to help me make full use of this great app.
IBM360 Model 50 - Still Learning How
Still learning how to use it, but it works great!!!
TheAlphaWolf TZ - Not sure how to switch the function
I am confused on how to switch the END to BEGIN on the TVM calculator? That would be a tremendous amount of help thank you. This calculator is helpful.
No nickname (lol) - Good ... but
When I try normalcdf it would give me an error.
There also no manual for it so it took me some time to understand on how to work it.
GooseHonkMan20 - Just like the TI-84
As long as you spend 5 bucks on this app, it works really well!Just like a TI-84 calculator
Mroses21 - Pretty close to the ti 84
I would like to see the solver function added and then it would be awesome
St(religion)ingz - Just like the real Ti-84!
This app has the exact same functions as the real TI-83 TI-84. My only piece of criticism is that the graphing functions could be better and more resemblance to the TI-84
Anaysteryoso - School help
It helps a lot for school as at home I do not have a graphing calculator
yellowslug - Calculator that can’t properly calculate
If you’d like to fail classes this is perfect! It has so many bugs and issues such as not being able to “seed” a number. Just bite the bullet and get a real TI calculator at least it actually does its job

Khanka Hard Case for Texas Instruments TI-84 Plus CE Graphing Calculator
Texas Instruments TI-84 Plus Graphing Calculator (Renewed)
The fact that a TI-83 Plus graphing calculator is still $100 is outrageous. It’s like 20 years old.
