Graphing Calculator Plus Positive Reviews

Buy if you need a Ti-84 !Have Financial Statistics for my first year of college, of course when they told me to buy a Ti-84 (upwards to about 140$) I was extremely reluctant and wanted to find a more affordable option. I downloaded their Ti-84x (the free version) , but it sadly didn’t come with all the formulas I needed. So I forced my bf to by me this one, and it’s absolutely amazing !! I understand that you may look at this and go “5 dollars, heck no” but trust me, spending these 5 dollars is way better than spending 140$ for a calculator you’ll never use again outside the class. There was only one instance where I had trouble, but before I figured it out myself, I contacted their Help Center, asking for assistance. Afterwards I was able to clear the error myself, but their help center reached out to me, giving me instructions on how to rightly input the formula. Took less then a day to contact me back, and they were extremely helpful ! Great app, great staff, and overall absolute perfection !.RswfsVersion: 2.9.6

How to exit “Y=“First off, this app’s purpose is to replicate the graphing calculator and make it much much more cheaper, so if you search up “how to use the TI-84 Plus calculator”, you can use a lot of the search results for this app. It’s really efficient. That being said, you shouldn’t give less stars because you don’t know how to use this calculator. They even provided a user menu for you! Anyways, to exit “Y=“ tap on “2nd” and “MODE”. You can literally see the “Quit” word right above the “MODE” button. If you are too lazy to find the buttons, you can still search it up on the internet, but your laziness isn’t the developers’ fault..4thenaCh3nVersion: 2.8.1

THE BEST CALCULATOR ONLINEThank you to the people that created this app and for only $4.99 ???? What a STEAL! I’ve never taken the time to write a review for an app but this app saved me from having to purchase an actual TI-84 calculator that costs over $140. I needed it for my college STATS class and only for the remaining 3 weeks of class so this was the best investment I made. I didn’t have any problems with my answers being incorrect because my professor would show us how she got the answer on her calculator and I would try it and always accurate! If you’re a college student GET THIS it’s worth it i promise!!!!.AyeeovoVersion: 3.0.1

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..Darth LightningVersion: 2.5.2

Great calculator but could use the medium betterI’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..Jwink3101Version: 2.4

Great app!!!!I needed a ti-84 graphing calculator for school and since I didn’t want to buy a 170 dollar on I just downloaded this app. When I asked my mom said said “oof, that’s a lot for a calculator” but I said should you rather me buy one that’s 170 dollars and most likely never use it again or just spend 5 on this app and save 165 dollars very good app and for those who didn’t know how to get out of y= press the 2nd button then press clear twice it should get you back if not then press 2nd + 5 enter to clear your ram..SdnocufuenvekfnvkejdcnldVersion: 3.0.1

Fully replaces TI-84This app emulates the TI-84 calculator on your iPhone; all functions are provided. The display interface is native and integrates with the iPhone display. The key functions are the same as the physical calculator plus touch screen function! The graph shows fullscreen. The developer is active in support emails and replied to my support request on their website within minutes! My issue was successfully resolved. This app saved me $100! Made in Vietnam, 2018. #14 in Apple’s Education apps chart!.ITboyVersion: 3.0

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..Nguyen TexasVersion: 1.2.1

Worth every penny.Don’t wait. If you’re debating getting this app, go for it already. This app has a powerhouse of features, and will blow you away with its features (surpassing the TI-84, yet the layout is the same?!) I never bring my graphing calculator to anything anymore- why bring it when you have this? This should be standardized. This app is what the calculator app would look like if Apple cared more about its customers 💀.Customer969Version: 3.1.4

What I wished I had earlierThis calculator is almost exactly what I’d imagine would be a tablet (and phone) based take on the advanced graphing calculator format. If Texas Instruments, Hp, or Casio etc came out with a calculator that was basically a modified small form factor tablet, this is what it would be. I only wish there was more UI customization (colors, button positions, function positions, etc)..EllgramarVersion: 2.9.6

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 missing it?.Freckled PandaVersion: 2.1

ProblemsI 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”..The original stephenVersion: 2.7.2

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!!!.QA.ProVersion: 1.1

Logs and multiplying exponentsThe 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.DbsjkaskdVersion: 2.1

Decent for what I needI’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..Coolninja0033Version: 2.7

Great, but one major flawThis 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..Randomblock1Version: 2.8.1

Many years of useI love this app and I’ve used it for years. Sometimes the tiny buttons frustrate me when I misclick but this is the perfect calculator to have in your pocket. I’ve never encountered any glitches with the app and it has been incredible to me for many years of both high school and college math/chemistry/calculus/etc..Isabella MobleyVersion: 3.1

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..Back to School StudentVersion: 2.3

Great app. Premium version is worth itWant a TI-84? This app does it perfectly and adds the better usability of your touchscreen. It also has good tips and help guides for everything the calc does. I bought it to familiarize myself with the TI-84 so I can teach my middle school and high school kids the tips and tricks to make Math easier. It’s been perfect for this..NickW3101Version: 3.1.3

Great Savings $$, Great ProductGot this for an Algebra class and thought I’d only use it for that class, but I find myself using it more than my iPhone calculator because it lets you reference previous calculations by keeping them on the screen as you move on to your next problem. Love it!.NYCNewbieVersion: 3.0

Graphing function errorI appreciate the cheap and accessible graphing calculator. My only complaint - often times, after plugging my function into the “Y= “ panel and then using the “graph” button to view the functions graph nothing appears! The graphing function usually works but when nothing appears, this can be pretty frustrating during calculus class.ReviewNameTak3nVersion: 2.9.6

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..Coolkid2461Version: 1.2.1

Good CalculatiorThis is a good calculator especially for the price. It is a little hard to find out all the calculations, especially things like the maximum and minimum. It has a manual, which explains almost everything, but unless you already understand the workings of more complex calculations, it is a little hard to understand. Overall great buy..GandalftechVersion: 3.1.4

Technical issueWhen 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?.Poor mathematicianVersion: 2.8

Horrible at graphingI 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.I_am_dante13Version: 2.8

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!.Matthew A. MusicVersion: 2.4

AmazingThis 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 👍🏼.WonderfulChrisVersion: 2.1

Best of its kindI’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..Hiko303Version: 2.1

Really awesome!I needed a to-84 calculator in a pinch last night for my homework. I was so worried I’d have to go to the store and spend the insane amount these things cost. This was only $5 and trust me it’s completely worth it. It had the functions I needed therefore making my homework so much easier! So grateful for this..TonadwtyyfshfVersion: 2.9

Very good but 1 thing lessSo I downloaded this calculator for the purpose of 8th grade having use of calculators at school. But when we learn about solving equations we press, y=and we type the equation, then we press 2nd but after that we’re supposed to press (Trace) and there is not a button on the calculator for that. So ya I wish ya had trace on there..Kaleylunabae120Version: 2.9.6

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!.Jrhea815Version: 2.0

Glad I bought itI 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..Austin vHVersion: 2.1

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!!!.IzNaz725Version: 2.5.1

Just like a TI-84Does everything you want it to, and well. My only complaint is that the sound/haptic feedback happens when you release a key, not when you press it. Just feels laggy and as much as I would love the haptic feedback it bothers me so much I had to leave it off..Gravis86Version: 2.9

PerfectI 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..SquidzzzzzzzzzzzzVersion: 2.4

Great calculator, a cosmetic update would be welcomeI use this all the time for my algebra 2 with integrated geometry course! While the $6 upgrade from the free counterpart is totally worth it, I would have expected an improved user interface since it is still a little crowded like the free version. Overall, great app, but it could use some visual renovations..JoshyKong19Version: 2.9

Love it.Got this app in a pinch three years ago, and since then, I rarely use my actual Ti-84 calculator. The pinch to zoom when graphing is way faster and more convenient then how you’d do it on the physical calculator. A must have for students on the go. 10/10 would recommend..Mello_neloVersion: 2.8.1

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!.Catattack13Version: 2.3

Great CalculatorI 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!.Minty111213Version: 1.2

BugsYes, 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..AnrunwangVersion: 2.0

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. 💯👍.Ben MackowskiVersion: 2.4

The best calculator appTrue 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.PlasticinVersion: 2.3

Where is the zoom button ?Overall the app is great and has helped me with my college statistics class, my only question is how do I find the Zoom button ?.Chrriss11Version: 3.0.2

Lacks statistical plotting functionalityThis 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.PyzkmuzkVersion: 2.2.1

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..Wat did diddy do?Version: 2.6

Graphing issuesWhen graphing an inequality such as Y=(0I don't need a nameVersion: 2.8

Good calculator app but not giving correct resultsI 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..Achu1234Version: 2.5.1

FantasticThis is the best calculator app I’ve found so far. It works on iPhone and iPad quite well and is well documented if you’re looking for a function you know should be there. The only thing I really want is having the math function history visible on the main screen on the iPhone like it is on the iPad for repetitive function inputs and maybe some different colour themes. I’d recommend this app to anybody even if they aren’t in a math course..BriansaloVersion: 2.9.6

ExcellentPeut-être une suggestion d’amelioration, permettre d’afficher plus grand. Sinon c’est un outil puissant..Sb3424675Version: 2.5

Needs more work on current featuresGraphing feature seems broken for me, also there seems to be no delete/back button aside from Undo at the top. For which the positioning is not ideal. Not to mention, this application needs some padding on the output screen, those are my recommendations, but either way I still tend to use a good-old fashion calculator..G-2HVersion: 2.8.1

Worth the cashInstead of buying a $100 calculator, I got this beast of a calculator for nothing. Does the same thing as expensive calculator..Trizzzle21Version: 2.2

Disregard my last reviewThis 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..NsgddhdhzjddVersion: 2.4

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?.Lblmj1996Version: 2.1

Graphing Calculator Plus Negative Reviews

Same as GraphNCalc83This app is basically the same as GraphNCalc83 which is free (possibly a GitHub open source project) another issue is that the fonts are to small GraphNCalc83 has larger fonts and is visually pleasing to your eyes other issues once downloaded I did not receive a receipt indicating I purchased the app which makes it difficult to refund and last it does not show up in my App Library on the device I’m not sure how or why this occurs but will consult with Apple on the issue..SofttechllcVersion: 3.0

Errors3^2(-1) makes syntax error 5*10^-4 gets a syntax error. Cannot handle negative exponents Not able to scroll back and forth through equation with arrows right. Clear and delete not working. Not quite sure how to edit an equation. I keep having to start typing everything over! That’s frustrating. Limited documentation! No obvious manual on how to use it. The help (?) button doesn’t have a lot of help!.Brixboston on IGVersion: 3.1

Some functions don’t workThis 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..Reviewer_appsVersion: 2.6
