Graphing Calculator X84 App Reviews

VERY HELPFUL!!☺️. Needed a calculator to use for my trigonometry honors class when I’m home, since I do not have one and didn’t want to buy a calculator that I might end up using for only a year. THIS APP has actually helped me on difficult problems on my homework and is very helpful to use when I need to Check my answers. I highly recommend this calculator app as it has helped me successfully complete my homework and avoided me from getting the wrong answers.

Ads. I have had this app on my phone for years. A solid addition to a STEM majors phone… BUT I could’ve sworn that I bought the ~$3 version to get rid of the ads, but in the last few months I’ve been SWARMED with ads. Every 2-3 minutes there are 90 seconds of ads. I cannot find the settings option anymore where I bought the ad-free version. To the ad developers, what’s up with this?

Features blocked by paywall/ too many adss. Downloaded this to have easier access to a graphing calculator. It was honestly a mistake. You get an advertisement every minute or so, and too many features are blocked by a paywall. It’s virtually useless for anything you might need a graphing calculator for. Truthfully it’s no better than Desmos in what it’s capable of. (at least with Desmos there are no ads and it’s free). Save your time, google will do almost anything you need.

This is amazing. I love this app so much I have an older phone so it is able to download from it and it is just amazing it solves equations that most use google to solve but instead just press two buttons and you answer

Nice and fast and easy to use. In my opinion this is not the best calculator on the App Store, but I am giving it 5 stars because it is the only one I like using. This calculator feels very fast and responsive and the buttons are bigger so they are easy to press. I would really love a feature to customize the size/font, but I still love this app

Great app other than the ads. I use this app to calculate weighted grades for my classes. It has features that make this easier than the stock iPhone calculator app. This calculator would be PERFECT if I had the option to pay to remove the ads. As it is, sometimes I’ll be doing a series of grade calculations and get interrupted by ads, which is annoying. Otherwise, this is a great graphing calculator app.

Too many adds. I used to have this. 5 stars. New phone and haven’t had the app in a while. I just downloaded it and there are so many ads, it makes homework so annoying. If you’re just doing a bunch of calculations you can do quite a few in between ads. However, I’ll enter a few numbers, go back to paper and solve a bit, need a calculator and have an ad. It’s that cycle over and over again. Right when I need it I have another ad. Without the ads it’s an easy 5 star. They just make doing homework so annoying

It’s a good Calculator, but horrible advertiser.. I understand why a free application would use ad revenue to make sure the service can stay afloat, but if I’m taking a geometry test, and my calculator is replaced with a billboard, maybe it’s not the best option. I don’t know why it happens either. There are ads on the top that are noticeable, and not obstructing anything. Good product, but the more obnoxious ads make me want to die.

So many ads. I swear I was on the app for a whole ten seconds before another money hungry add just pops up in the middle of an assignment due at the end of class, then I had to wait 30 seconds for it to all be over with just to get another one in another 30 seconds, if you like watching ads and wasting time instead of doing your work then this calculator is just for you.

OHMSMRHGKDI. I love it I don’t have to buy an expensive calculator (I’m in 8th grade algebra) and I can now do all the stupid things instead of struggling with google. Thanks would be 5 if all features were there (wish I could put 4.99 stars). But I see why it isn’t unlocked but hey I still enjoy it. :)

Amazing!!!. Instead of going out and buying myself a $100 TI-84 calculator for class, this app is the exact same thing! It’s perfect for school in the sense that this app is free compared to the expensive physical version of the calculator, and it works the exact same, arguably even before than the physical calculator. Overall, I love it! Would definitely recommend to all students to download this app rather than paying for an overpriced physical version of this calculator.

A M A Z I N G. I am always forgetting things at home/leaving them places, so I don’t trust myself to get the $100+ calculator (which is so clunky!) This is amazing! It’s just what I need and works very well. I haven’t updated to the paid version yet but I plan to do that in the near future. Something I love about it is that I can type out the numbers I want to put in the calculator on my iPad keyboard (I’m one of those people who uses an iPad instead of a laptop, with a keyboard attachment and everything) which is like the most amazing thing ever! I didn’t expect it to do that but it’s a nice surprise!

Do not buy!. Do not buy this app. It all looks good until you actually try to use it. It has no complete user’s manual, it doesn’t do any of the calculus operations, the customer service for help does not exist, very poorly designed, very hard to figure out the operations. I have worked with TI 89 in the past and it was great. But this software is just a scam. They just want to make a quick buck by making the app pictures very appealing and nice. But don’t fall this!

Meh. I only needed this app for a few minutes I’m in 8th grade and need a graphing calculator for 1 lesson I’m not a school and have to do this lesson online. It was working great until I tried to do an equation then it said I needed to purchase this app to complete the equation. I understand that $5 isn’t a lot compared to the $100 or more ones but when you need it for 20minutes or less to complete the homework I don’t think you should have to pay. I know they need money and stuff but at least let your customers have a trial or something in the future. Just a suggestion but I think it would improve the app and more people would want to buy it. I know when I get free trials I find the full potential of the app and am more likely to purchase it. I really don’t mean for this to be rude it’s just a suggestion you can take it if you want but if you don’t I don’t care.

Useful. I want to get rids of ads, though. Listen, I’m not saying you make this app free without any ads. I understand, I’d want to make money too. I was referring to paying a small extra fee to get rid of the ads altogether. The ads get in the way of studying and I’d much rather prefer pulling the sting out. If you do have a payed ads free option, I would like clearer instructions on how to buy it -for dumb fellas like me ;). Either way, amazing app. P.S. If anyone knows a way to do it, respond here, please

online classes. because of the corona, i've had to take online classes. I'm only in 8th grade, but i take high school math classes, the school usually provides the graphing calculator. They just started sending me work but i didnt have a calculator at home because of money. This is a life saver!

Works well but a lot of ads. I’m just very burnt out on ad culture, and getting an ad every other time (not joking it’s a coin flip) I hit enter really isn’t great. Like, I’m in the middle of trying to put an answer in Aleks, and when I look down to confirm I put the right numbers in, it’s Raid Shadow Legends. The calculator itself seems to work great otherwise

Amazing 😊. This is very helpful. Helped me get all my school work done. If no one wants the adds to pop up, all you have to do is simply turn off your wifi. Solid Calculator and very useful, especially if you lost or forgot your actual graphing calculator.

Appalling casino ads. I tried this out and was in the app for 10 seconds. When to my horror a loud casino slots ad appeared, and filled up the screen. It lasted at least 30 seconds and did not go away. I tried to find a way to close the ad but it was impossible. I closed the app and will find another calculator app. Even one that I have to pay for. But I will not pay anything for this app.

Useless!. This app is a GRAPHING calculator application, but to calculate anything that involves graphing, you must pay! At that point, you might as well just use the calculator that’s already on your phone instead of wasting storage and time on this sorry excuse of a calculator. I would just recommend buying a graphing calculator, even though they are expensive. You could also switch to Samsung and get the wabbit emu calculator app from the Google Play store. It’s free and exactly like the ones we use in school.

Good app, but you really only use it for one thing. The only, THE ONLY, reason I use this calculator over any other free calculator is because it helps with Algebra II specifically. Specifically it’s the only free calculator I’ve found with the T-84 features of graphing and matrices. Otherwise, I’d just use an online calculator because then I don’t get bombarded with ads while I’m trying to work. If you remove the ads, then it’s a great app. As is it’s really only something a student in algebra who can’t afford a calculator would want.

Depends on what you need it for. If you need to do some quick calculations and you dont have access to an actual calculator, it works fine. However, the app will make you purchase anything that doesnt fall under basic math so be warned if you're trying this app for graphing, finance, etc

Too much ads. I know this is my responsibility to bring the graphing calculator but I forgot. I was taking an SAT practice exam and I didn’t have the calculator so I downloaded this app. Every 10 seconds, it is always showing temu app, buying clothes, other ads and it is so annoying. I got very frustrated and I kept trying to close them and the teacher saw that I was suspicious so she came up to me and asked me to show her what I was doing. I showed her the app and I accidentally clicked the temu ad and it took me to another website and the teacher started to yell at me. She said “if I see u switch screens again I will take your phone away” but if I don’t use my phone, how will I use the calculator?? This was such a disappointment but the features of the calculator was pretty good besides the ads. I mean which other apps give ads every 10 seconds?? It’s such a distraction

Use it for school. I love this app! I think it’s absolutely amazing it helps with my homework and class assignments. Teachers might say put your phone away but hey it’s still a great app and I recommend it to any high school/college student.

For class. Taking college courses and I used to own a ti 83 but I lost it when someone broke into my house and needed a quick fix. After using this app, it has, basically, all of the functions I had on my ti 83 but is significantly more convenient. I was able to open it and use all of the functions pretty quickly, as it was easy to learn how it all worked.

Doggo app and waste of time. The sin, cos, and tan, buttons put different numbers than the actual calculations for the numbers. This app has multiple errors like giving the wrong numbers. I just do not want other people to waste their time on this app, when the normal, free, pre-downloaded calculator works better. I don’t normally write reviews at all but this app ticked me off when I thought I had a good working calculator, just to experiment and figure out that he calculations are wrong. I am sorry for the paragraph, enjoy your day unless you made this garbage app. If so I hope you eat Taco Bell and explode everything in your stomach into the toilet water and it splashes all over your stupid face, screw you.

Best Scientific Calculator. This is by far the best scientific calculator in IOS. The keys and function works just like the real ti 84. To me it's better and very convenient because you can get this app for free and use it anytime you want on your phone. Best Calculator hands down!

AMAZING MUST HAVE. When I was in 7th grade I downloaded the TI 84 C wabbit emu and I loved it! This is basically the same thing just FREE (you don’t have to also own the calculator...which I think you need to do for the emu)! Basically this app is everything I ever hoped would exist for iOS with basically the same layout as my number one favorite calculator. I LOVE IT!!! only small prob is the numbers at the very top of the display in the corner seem slightly cut off, I hope this gets fixed in the update but don’t let that stop you from getting this AMAZING app. It will change your life :)

Adds pop up = not free. Got this because I just wanted a scientific calculator for my iPad, and it looked like there were no in app purchases that would require for me to pay anything. Turns out about every minute, an ad will pop up, which to me makes it not free and pretty frustrating when you’re trying to do calculations. Deleting this one immediately!

Best graphing calculator on the iPhone. I think that it does a very good job. I like being able to have the graphing calculator on my phone, it does the minimum so if you want it to do a specific action that isn’t that basic you might have to pay. All around I use this app a lot when I need it.

Great cheap full featured ti84 emulator. Needed a $100+ calculator for school, bought this $5 app instead and couldn’t be happier. Works great on iPhone, iPad, and iPad multitasking modes all perfectly fully fleshed out TI84, recommended to any students or anyone who needs a great IOS calculator

Solid. This is a $5 alternative to paying $50-$100+ for a physical calculator you might use for one, maybe two classes your whole life. It works exactly the same as anything that costs ten to twenty times more and it’s right on your phone. The creators of this app deserve the 5 star score; higher education is already expensive enough. If you don’t want to learn how to familiarize yourself with statistic functions on excel (which students get for free), then this is the next best thing. Great app, thanks guys!

Prepare for ads. I ended up having to delete that app over the ads. I’m fine with the pop up ads, they have to make money somehow, but the time based ads that take up your entire screen was enough to make me quit. It’s highly annoying when you’re trying to do quick calculations for homework and an ad for a social media site completely takes over what you were doing, especially when you’re trying to avoid those sites and stay focused on homework. If that isn’t an issue for you, then it's not a bad calculator. I never tried the graphing. I use my actual TI-84 for that, but for other simple calculations, I think it’s better than the regular iPhone calculator.

Great app!🤩. Best calculator I’ve ever used! I strongly recommend this app to anyone, especially high school students who are having trouble. This App even has a graphing table and everything that you would need. Not to mention that it’s cheaper than the $100 philosophical ones. Although I would like this app better if I was able to customize it a bit but that’s pretty much it 👌🏻

Too many ads. This app was good for school, however there is a timer so that every 100 seconds there is a full sized ad that stops your ability to use this app. They also have ads at the top of the page which is okay, but stoping my work so that I can have a full sized ad is too annoying

Great Calculator. The calculator is great. Would be even better without annoying pop up ads in middle of trying to enter numbers

I tried to like it i used it for a year but the ads are too bad. they pop up at the worst time and if you are like me you will have found that every time you want to perform a quick calculation the ad will pop up and slow you down and maybe even make you click on it. after years i cant take it with the ads anymore. they should just offer it as a paid app instead maybe

Ads auto-playing. Do. Not. Download. I’ll keep this short, not only are there banner ads on screen, but they’ve added a feature where video ads start auto-playing in the middle of calculations. You cannot stop, pause, or exit out to continue to the calculator portion until the ad finishes playing. It was an immediate uninstall for me and my first ever review of an app. Utterly infuriating. Do not download.

Relentless Ads. It seems like nowadays you can’t utilize a single product without being throttled by a money grabbing ad every 5 seconds. It is ridiculously infuriating. What makes you think we want to see an ad every 30 seconds of calculator use? You think I’m having fun in the first place doing my calculations? Yes, and an ad will brighten my day and make me give you all the monies. I shocked by the overall good rating this app has. DISGRACEFUL.

Paid Programming. The entire reason I have been looking for an app for graphing calculators was to use the programming function. That’s the best part of a graphing calculator, being able to program in commonly used equations to make math faster and easier. This app put that function behind a pay wall. The only reason this isn’t a 1 star is because the actual calculator part works great. However, this is not a free alternative if half the calculator is not free.

this app is amazing. like the title said, this app is absolutely amazing. i have to use a graphing calculator on almost all of my math assignments now, and when i can’t do them in class, i have no graphing calculator at home, until i found this app. absolutely amazing, the layout is almost identical to the actual calculator, and it runs so quickly, smoothly, and accurately. thank you, developers for creating this wonderful app that is necessary in my math class. ❤️

Free alternative to the heavy calculator. I often had my calculator with me all the time! But it isn’t necessary anymore!!! I got this one! It has all common functions (even including complex and statistics), matrix calculation also works on basic operations! That’s by far the BEST choice you can get for the zero cost!!! A big thank to developers, i hope you guys’ll carryon well!!!

Annoying attempt at a demo. This is not a functional app. When you try to execute any of the functions it just says "Buy the Pro Version" but there is no option to upgrade or In-App purchase. They want you to buy a whole separate app in the app store called "Graphing Calculator Plus" at which point this app is useless. And this "demo app" doesn't even let you try out the functions of the real app before you buy it. It constantly interrupts you every few seconds with video ads while you are trying to enter the data to do a function, and then it doesn't do the function anyway. The user interface is not adapted to MacOS, the keyboard doesn't work so you have to use the mouse to click on all the buttons. So many things. Whoever thought this would be a good idea to promote interest in the paid version was wrong, very wrong.

LITERALLY JUST DONT GET THIS APP. This app was not great, I use the Ti84 calculators a lot for my schoolwork and this was just not it, it is missing many of the functions that the ti84s have and there are constantly adds popping up at the top. It is also confusing to use overall. Many things need the upgraded version that is like three dollars and I’m just not going to pay that for a calculator that should already have all of the functions on it.

Ads Are Something Else. I’ve used this app for years and the ads have been fine. I understand they are necessary for the app to be free. Previously, all the ads were quiet and relatively reserved in nature. I’d see an ad for Raid Shadow Legends and move on with my day/calculations. So I’m sitting in class today doing some math when I get an ad on my calculator of some girl yelling “My boobs are DDD!!!” Mind you, it wasn’t a quiet ad. The ad took over my phone speakers so everyone in class could hear it. My phone is silenced, because it always is since I can’t use it in class. Why would it do that? I have no idea because it’s never happened before. Now I look like some creepy perv in my graduate course because of a calculator app. It’d be funny if it wasn’t so detrimental to my professional life.

Crashes Randomly. I’m in 8th grade and we have to take algebra tests at home because of the coronavirus. I downloaded this app because I thought it would help out at home without the calculators the school provided. However this was not the case this app is buggy and glitchy I was doing the test just fine up until it randomly stopped graphing their 5 dollar alternative is the same with a few more function. Overall please don’t get this app and if you do do not get the five dollar version it’s just as bad.

A big help for complex problems!!!!. Whenever I need to figure out complex problems this baby is my go to. Simple to use and great for business, especially when you’re out and about and need to crunch some numbers in right quick.

Suggestion for an Update or Question as to How to turn on Haptics. Love the app but could you add haptics so whenever users click on a button, they can feel that a button has been clicked? It’s just something that feels reassuring for some users and users can always turn it off if they don’t like it.

Does it have STAT Diagnostics?. I was just wondering, is it in the paid version? I couldn’t find it in MODE, and that’s what it’s on on the TI-84. I am doing lines of fit and correlations for some background. Also, I love how the age recommendation is 4+ when algebraic calculators are for, like, 8th graders. I’m in 7th and doing algebra though, ‘cause I’m big smart. Sorry to flex 😂😂

My Grandson Update. My Grandson did an internship with me this summer. It required the use of multiple calculations. He kept coming up with the answers very quickly. I thought how his doing this. Then he told me about the app. So he installed it on my phone and now I have it. It has been so helpful. Great calculator - thank you - Papi and Jaykob

Adds and restrictions. Holds functions and uses behind a paywall

ADS. Ads ads ads ads ads ads ads ads ads every second. No literally I’m not kidding just ads constantly

X84 Texas Instruments. If there would be a button that you could press that references to a manual if you are trying to get a specific function working that you are not quite sure about ????? of course you can google but a button on the virtual calculator would be more appropriate

The best app. Truly, I have wanted to find this for andecade and can finally rest

Love this app. I love this app it has been so useful for homework at home when I forget my calculator at school!

Add every 15 seconds. There is ads every 15 seconds and when you want to do graphing you’re forced to pay

Awesome but add vibrations!!. Add some kind of haptic feedback when pressing buttons pls :)) at least the option to turn it on!

Calculator made of LIE$. This app hides the fact that it will still request an upgrade price for certain calculations, despite the App Store not announcing this in its stats.

Doesn’t fully work after purchasing. The calculate function doesn’t work neither does the delete button and there’s not an option to intersect. Do not buy for anything school related. Fix or I want my money back

Handy way to find paid app. This is a great tool for finding the paid app in the App Store. Otherwise, it might remind you a bit of the TI-84, unless you want to graph more than 2 lines at once. Weirdly, the screenshots show a graph with 3 lines, but, of course that’s after you use this tool to find the paid app.

Used it for years. Worth it!. I’ve been using this app for about 3 years now, in high school and now in my undergrad. It’s pretty much an exact replica of the ti-84 the layout is the exact same. This app works brilliantly on the iPad and my phone. It does have ads but they’re not common. I only get one if I quit the app and open it again or if I haven’t used the app for several hours. But if I’ve used the app for multiple hours at a time and I only get one ad when I first open. It’s fantastic for basic use of a graphing calculator and it’s free!

Ad Spam. Is an ad after every calculation really necessary??? Can I breathe or no?

The update is it worth it?. I bought this app to help me instead of buying the expensive calculator but this appt isn’t doing much more then a regular calculator at this point. How do I access the probability simulator in this calculator? What is this app equivalent to in-terms of a graphing calculator, so I can research what I need to access? Please help me or refund my money because I need this for school!!!

Forgot my to 84 CE. This works well enough for today, even just free, wish I could use Y=3+ just for a bit though, just in case.

Review. Was recommended to me by my math teacher however this calculator is poor. It is hard to navigate and doesn't provide and help with understanding what it can do. It also spams you to pay for the “extra” features even though there are better FREE resources out there. To all reading this don't waste your time with this app.

Suddenly the Google ads shown? Why?. A great app. But it is so annoying with the Google ads.

must pay for basic functions. you have to pay for some of the most basic functions like tvm solver and others

Ads after every calculation. It pretty bad that I get an as after every calculation that I do.

too many ads. it’s working pretty fine, but i’m getting ads every goddamn minute.

useless. there's so many frickin ads don't get this it's useless and to do anything the ios calculator can't do you need to pay 9 dollars and they don't shut up about it every 2 seconds they say UpGrAdE tHe ApP tO uSe ThIs FuNcTiOn

Apha button. Didn’t not turn into alpha when pressed

Very good calculator it definitely saved me money having to buy one. It definitely

Terrible. Of course the one time I use this app on my ipad because I’m doing a time limit questionnaire on my phone, I get a math problem and with 15 seconds to do a short equation an advertisement pops up and I cant answer the question. It’s my fault for not having a real calculator and relying on a free app. Now I’m taking out my frustration on this App Store review. This is what my life has come to. Just end it, please.

Waste of time. Trying to do math work and I can’t do any calculations without paying

Calculate. Best calculator I’ve ever seen, it’s basically the regular Ti_-84 but on phones

Adsterra is the most preferred ad network for those looking for an alternative to AdSense. Adsterra is the ideal choice for new sites with low daily traffic. In order to advertise on the site in Adsterra, like other ad networks, a certain traffic limit, domain age, etc. is required. There are no strict rules. Sign up!

Recommend. Works great, might not be able to use it in class though

Terrible for any complex formulas. I am in AP STATISTICS and was an effective online tool for help and came across this. Upon entering, it appeared to have very few functions that could be used without purchasing, but the sad thing is that this app doesn’t hold some features the TI84 includes. One thing being a scatterplot which I was looking for. Would not recommend this app.

Great substitute. So far it has been a great substitute to have. Still enjoy using my actual TI. But when you are in a tight crunch,this does the trick. Haven't used any of the graphing features yet. Use it primarily for basic math.

Annoying ads. There is an ad after every equation just find another app and save yourself a headache

Life Saver!. a little bit of a learning gap because of button placement but saved me after forgetting my to 84 at my father’s place. 10/10 would recommend

Best Mobile Calculater.... Easy to use. Has very convenient features such as: clicking on previous answers to add to current equations, easy to find previous answers etc.

It’s amazing. You can like type in any number and it’s perfect and there’s barely any glitches I never had a glitch every

Held back by ads. A nice calculator app with the necessary features held back by intrusive ads. What a shame. I wouldn't mind paying a couple dollars as an additional purchase if that meant I can support the developer while having the ability to use this app ad-free.

The only calculator I use.. I downloaded this because I needed a calculator for my math class. I had no idea that this is what I needed. It has all of the functions that I need for my math class.

Great. Minor bug. It mostly does what I wanted it to do and it’s programmable in BASIC except there’s a bug with Output(. Subsequent Output( commands on the same row erase everything along the way instead of starting at their specified coordinates. Output(4,1,”Status:” the string will be erased by Output(4,9,A) and all that’ll be on the row is the value of A. Status is gone. I hope I explained that well

Good while it was free. This was a fine app, until it decided in the middle of a quiz that my free trial had expired. This confuses me, because I don’t see anywhere that it’s free for a month and then to do anything more than simple math must be paid. Why did I have to deal with ads then? I’m switching to Desmos.

You Have to Pay to Graph. I’m a 7th grade doing Geometry and I need an online calculator since my school isn’t giving calculators out this year because of COVID. I thought I’d give this one a try since it had the best rating, but this turned out to be terrible. You can’t even call it a TI-84 calculator if it doesn’t have the graphing feature for free, that’s a scientific calculator. This app just takes up space and don’t get it if you need a real TI-84 calculator.

Made me fail multiple assignments. I was always wondering why I was getting calculation errors when using this app until I started using my physical ti-84 and compared the answers I was getting on both calculators. The math on both calculators would always have proper parenthesis where needed and yet still this calculator would give me the wrong calculations.

Annoying ads. They make you watch an obnoxious video ad after every equation you solve. If you are doing a lot of calculations, you're going to watch hundreds of ads. It really hurts my focus and takes me out of the homework mindset, being distracted by ads several times per minute

Very useful. It’s a useful app because I don’t have to pay over a hundred dollars to get it and it’s on my phone which is a big plus

Nonstop ads. I understand apps have to make money somehow, but ads every 10-20 seconds is extremely excessive and drove me to delete this app just 5 minutes after downloading. Certain calculations like standard deviation (what i mainly downloaded this for) cannot be made without "upgrading" the app.

So cool. Omg don’t get me started on this literally amazing app! I am absolutely in love with it! I know it’s a calculator but holy cow! It doesn’t get better than this. I am sooooooooo in love!!!!!

I wish we had smartphones in High Schools with apps like this.. I can remember when I use to but my Calculators for $85 back in my days. This is by far much butter with the same tech. Job well done.

😑. I love this app and it is great for math I'm just scared that if we go online I will fail because I don't have money to pay for the premium. Mabey try making a few more things free. I don't know it's up to you.

Way too many ads too frequently. Forgot my calculator today, and downloaded this one…ads as frequently as every six seconds. So glad I can delete the app after today. Absolutely infuriating. You can’t even judge when the next ad will be, forcing you to redo some of your equations.

Good ig. It works but it haves a lot of commercials and sometimes it mess up your calculator and clear it out but other than that it works.

Too many ads!. The ads are incredibly invasive. They pop up about once every 30 seconds and fill the entire screen. This app was on my phone for about 2 minutes before being uninstalled.

It’s okay, unless.... It’s a good app and can do every thing the ti84 plus can do but not for free. If you’re in a high level math class and need to enter more than 2 Y values to graph you’re outta luck. And also I can’t graph radians at all unless you have the payed version. The sigma is hard to enter the summation index on because the box is so small.

"free" means polluted with ads. Banner ads reduce usable screen space. Full screen pop up video ads completely block access. This makes me hate any attempt to use this app. The paid version may be just fine but I suspect the developer will just find more ways to annoy me and blackmail us into paying for basic features or to make more ads go away. Screw you, I bought the real calculator instead.

Very Helpful. Easier to use than other calculators, but still gets the job done. I highly recommend this as a tool to replace your usual calculator.

Why would you download any other calculator?. The only full-fledged calculator on the App Store with no ads OR in-app purchases. Insane! You’d have to be crazy to install any other calculator app.

My Students Will Love this!!!. This is the closest free calculator to the TI84plus calculator. I teach math at a HS. I will recommend this app to my students now instead of Desmos. With the free version of this app you can only graph up to two equations at a time. You must pay for pro version to graph more at a time. I just delete what was in it and graph a new one. Works great. No adds!!! In the free version!!! Thank you!!! I will spread the word about this calculator!!! Keep up the good work!!!

Exact calculator!. Yooo thank you so much!! I saved myself 100+ dollars for an online math class that required me to use this calculator thank you thank you!!!

Convenient!. So convenient when I don’t have my calculator with me! Still hoping to find the insert feature and the delete feature.

Ads are forced open!!!. The ads are TERRIBLE!! They make it so you loose focus. Because it was free I didn’t mind the first 2. However, after the third ad, it didn’t allow me to get back to the calculator! Allow us to exit the ad once it’s done playing please! I don’t want o accidentally purchase another app! That should be illegal!!

Thank you SO MUCH!!. I literally had an assignment due next period that wasn't even started yet, and then i got this app, and it helped a BUNCH. THANK YOU!!

To many adds. While waiting on my TI-84 I found this app that I thought would do all I needed (and it does). However it gives a startling Ad after almost every problem -_- Or else this would be a 5 Star App

WAY too many ads. The calculator works great, but there’s an ad every 10 seconds, so it’s almost impossible to get any work done

Disappointed. As a student this utterly disappointed me, math is one of my hardships and I need a calculator like this at home. Five bucks for an upgrade isn’t worth it. For a moment I thought I finally found something similar to what I use at school, but no, more like a slap to the face. Should’ve read the critical reviews before finding this out. Don’t make the same mistake and read the critical comments.

No surprises. No ads or anything else other than a good graphing calculator. The only thing it doesn't have is CAS, but if you weren't planning on using that, this app has everything you need.

🙈🙈🙈🙈🙈🙈🙉🙈🙉🙈🙉. When I tried to put in alpha y= enter it told that I had to make a purchase I was so upset because I wanted to be able to do that exact equation and I couldn’t so if the people who made this can make that equation free that would be great and you can make a different equation cost money maybe

Okay but has flaws. I am in 8th grade so I do not understand why I must learn this, but I am upset you can’t say what your variables equal, like you cannot say x=3 a:d the take the square root of x without having to PAY! You have to purchase a full version and even more basic math cannot be unlocked without an account.

Equation. It wouldn’t let me do an equation I wanted to do Because it said I have to upgrade and to upgrade it you have to pay so what did I do because I’m not paying

Definitely a good app to download. This helps me so much! Since we are in quarantine I don’t have the calculators that we have in math class so this helps a lot!

Does exactly what it says. Let’s me use graphing calculator with our spending huge amount of money, and portable. It’s a little hard on a phone (every thing is crammed together) but on the iPad it’s amazing.

Horrible. Ad after ad after ad, i’m watching more ads than i am doing my homework. it’s been 30 minutes and i’ve gotten two problems done. then when i’m finally finished, i get a notification saying i need to pay to get the answer. Why let me get up to that point and waste my time.

LIAR. This helps confirm the observation I’ve made that when anyone has to put FREE in all caps, they’re actually saying that they’re a LIAR! I have made in-app purchases with things before, and might’ve been more willing to buy your other calculator if you had been more honest with the way you sell this app, but instead you hacks feel like you need to deceive us, so I just deleted this and looked for something else.

Best free calculator app!. This calculator is the best one I’ve found for doing higher levels of math. However, you can not program it unless you pay for the full version :(

Whoah! Will be searching for donation link!. This is the best! Liberation from hefty calculator with clunky buttons. Others don’t compare, and this one is free, saving students and professionals around the world. Looking to donate to make this possible without cost

This calculator is amazing!. Just like the ones we use at school! Easy to use, fast, and very convenient. Used for 3 hours. No complaints

Still gives me advertisements despite Purchase. This thing is so annoying. I “purchased” the app and it still gives me TONs of add every 5-10 minutes and it’s super annoying. They are loyal and you can’t use the calculator while they play! Has ads up at top of screen while I’m using the calculator as well. This app is AWEFUL!

Suddenly ads. I’ve used this calc app for a couple years and suddenly ads start taking over while I’m trying to work. Why the change? Got greedy? Taking a star back.

Simple, as it should be.. This calculator works, has no ads, and does not bombard you with "premium" features. I love the simplistic, straight to the point layout.

Put a game. I think that it’s a very good app and that I just want math to be easier to learn and you made that happen. What you should do is add a game to the calculator. It would make it more fun to learn.

Educator. I love this calculator, it has everything that you can possibly do with it. It very easy friendly to use . Just have to play around on it. Love it.
