Graphing Calculator Plus App Comments & Reviews

Graphing Calculator Plus Positive Reviews

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..Version: 2.8.1

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..Version: 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..Version: 2.4

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..Version: 1.2.1

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!!!.Version: 1.1

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?.Version: 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..Version: 2.7

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.Version: 2.1

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..Version: 2.8.1

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..Version: 2.3

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”..Version: 2.7.2

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..Version: 1.2.1

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?.Version: 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!.Version: 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 👍🏼.Version: 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..Version: 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..Version: 2.9

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!.Version: 2.0

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!!!.Version: 2.5.1

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..Version: 2.1

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..Version: 2.9

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.Version: 2.8

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..Version: 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..Version: 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..Version: 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!.Version: 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!.Version: 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..Version: 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. 💯👍.Version: 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.Version: 2.3

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..Version: 2.6

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.Version: 2.2.1

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..Version: 2.5.1

Graphing issuesWhen graphing an inequality such as Y=(0Version: 2.8

Awesome AppThis 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..Version: 2.0

ValThis 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..Version: 2.7.2

Absolute Must Have For College-Level StatisticsThis app is an essential program to have when taking college level statistics classes to help perform distribution functions. Easy to use and great value!.Version: 2.9

One of my Top 5 appsI 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..Version: 2.2.1

TI 84+ appI 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?.Version: 2.5.2

CHEAP & (only difference is: it is in your phone)What is there to argue why you shouldn't get the virtual calculator aside from teachers insisting ("physical calculator needed to prevent cheating") ?? You will save a lot of money going for this calculator..Version: 2.9.4

I’m Very SatisfiedAbsolutely 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..Version: 2.0

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!!!!.Version: 1.2.1

BeautifulI had the free version for a while, and because of the math class I’m in needed the full version. For $5 this graphing calculator is amazing! I’m doing the same things as my friends $200 TI-84!.Version: 2.9.6

Only Good TI-84 Replacement AppThis 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..Version: 1.2

Annoying advertisingI 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..Version: 2.7.2

We need the equation solver appGreat 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!.Version: 2.0

ProgramsThis 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.Version: 2.3

Can’t change ListsThis is the only reason I got this was to use linreg for chemistry, but instead of having a screen that pops up and allows you to change which lists it inputs there’s nothing. This means that I can’t do many things a normal TI 84 can..Version: 2.9

ExcellentPeut-être une suggestion d’amelioration, permettre d’afficher plus grand. Sinon c’est un outil puissant..Version: 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..Version: 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..Version: 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..Version: 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?.Version: 2.1

A little help, pleaseHello 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???!.Version: 2.1

Nice job.This is an excellent calculator..Version: 1.2.1

Un ordinateurCe 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....Version: 1.2

It is great!PLEASE update the GUI of infinity calculator. That app deserves to be as cool as this one..Version: 1.1.1
