Graphing Calculator (X84)

I wish I could clear my memory but sadly with most of the features locked apparently I can't. It's a shame when I'm looking for specific stuff or for tests bc we're asked to clear our calculators so we can't cheat. The graphing also isn't particularly the best with the settings for zooming and all. It's very easy to use and incredibly helpful when I need it. Just wish it wasn't so hard to clear my memory really

Exactly what I needed. It's functional, easy to use, and looks decent. No in-your-face ads or essential features locked behind a paywall (though there are premium features like being able to render more than 2 graphs simultaneously). Overall very solid app.

Does more than the TI-84 but not as friendly. Needs to have template for the statistical tests like the TI-84. The list syntax is confusing. Also, in app font adjustment would be a big plus. Type is tiny.

I needed this calculator to do online school but not having the ability to use all of the features is a huge setback. I can't find another one online so I was relying on this app and sadly it let me down. I like how the app is set up and it works pretty well. ( with the little you're able to do anyway )

The only reason I would ever want a graphing calculator app would be for the poly solve function because regular calculators are good for most other things. But here, the poly solve function, what I think should be pretty basic, is locked behind a subscription.

This app is great for TI-84 users. One problem though, not configured right for tablets. The text is cut in half, making it hard to read. Been that way for years. No problem on a phone.

Looks like it MIGHT be an awesome app, but you can only try about 3% of its functionality without upgrading to the pro version. There are a lot of calculators out there. Pity you can't unlock full functionality for a day or two TO try it out.

Super cool design and really really a lot of functions. Please check the app on OnePlus devices running Android 10, 1st character is not visible due to rounded screen and app running in fullscreen mode preventing bottom control to be there all the time. Thank you.

Alot of people like to get annoyed that there is a paywall but if you compare it to the real thing about $5 is a lot less expensive compared to $120 to about $150 and it has a very nice layout compared to alot of other ti apps and compared to other apps it's not as annoying and has its own guide book. Overall this app has been alot more useful compared to other ones that are also free. Please use this it's alot better than other apps and won't make as much of a dent in your wallet.

I downloaded this app simply because I needed a few probability buttons for my Algebra II Prob and Stats unit. It didn't let me use it at all before asking me to upgrade to pro. I understand that the app needs to make money somehow, but it's really frustrating when I'm a high school student with no money and can't do what I need to for class since I'm visually impaired and can't use regular calculators.

It serves its purposes great, but forcing you to pay for something basic like the CALC function in graphing is a bit scummy, especially when it's needed for most of the things done in school. I recommend you find another one if you aren't just using this for equations.

I downloaded this to complete a specific homework assignment, and the function I needed was only available in the pro version which I needed to pay for. I found this extremely frustrating. Please don't make a demo calculator app. Either make it completely free or completely paid for.

Has plenty of functions and is effective as a graphing calculator though some functions may be hard to find, they should change the lighting on the keyboard, and some odd spacing between numbers occasionally

So far the only complaint I have is that you can't zoom in on the graph while keeping the same aspect ratio. You aren't zooming, just changing the scale of each axis individually. Other than that, though, this is working great.

A useful app that I use everyday for work. My one complaint is that the bottom buttons overlap with the virtual home buttons meaning I sometimes accidentally close of of the app when going for the decimal point.

"Watch a video to continue with the upgrade" in my case I was trying to use the LinReg function to plot my data. After the video it clears all my data points and doesn't continue with the function.

I have to paid. YOU HAVE ADS. USED IT. In college trying to do matrix and I can't because I have to paid. Used the ads to get pro or don't used ads at all. Because you are the reason why I'm failing this test.

Once enter x to a degree, no way visible to get out of upper degree! I want to get back to entering more regulars variables, not more degrees???!?!?? Won't let me out. No clear instructions

bought this instead of 'calc 84' which is better. both feature same interface but, come on, fix the delete, clear home error, no extra hyperbolic nor trig function! i regret this purchase

All I wanted was to finish my math assignment, but I couldn't find my calculator. I download this, try to watch the video to unlock it, and it won't do it. You shouldn't have to pay for a free calculator, and if you're going to say that you can unlock it for five minutes by watching an ad, you should keep the promise. 1/10, do not recommend

I have had no issues with this app, and it has several nice features that my Ti-84 lacked, such an undo button and the ability to handle numbers over 10^100.

Has all the right information and is easy to use but you have to pay to use all of the settings. When you need this kind of stuff for homework you dont want to pay for it. I think it's really unfair that it is limited when most kids in school would need things like this for every night homework. I hope that this will be changed in the future. Thank you.

In my trigonometry class, my graphing calculator, a TI-84 PLUS, doesnt have all the capabilities I'm needing to solve the more complex equations. I AM SOOOOO THANKFUL THAT I GOUBD THIS APP, which is perfect for everythibg i need at this time!!! Even cooler, IT'S 100% FREE so i dont have to go out and purchase yet another calulator...

New update messed up decimal calculations. Any calculation with a long decimal sends back a ridiculous answer. Super disappointing, will have to use a new app from now on. Have used all through college until now.

I paid for the Pro version, but so many functions are limited. I can't use, for example, binomialpdf calc. It gives me an error. It sais Domain.( I tried with n=1000000, p=0.005, x=49). And this happened with other functions too... Sad...Hope you can fix this issues. Thanks!

This is just bait to purchase the pro version. I can't list a simple function as it tells me to upgrade to do so. Controversial to the indicated "free" assumed wording used in the app profile.

Not bad calculator, it's good to memorize the results during the calculations; It's necessary to memorize/store the calculations even if we close the application.

It was nice to have this app because I am in high school and I forgot my calculator at school so I couldn't use it for my homework. This app helped me compete my homework but I needed to watch a video in order to get a function needed for my homework. I could not pay for this function I will continue to need because I am a poor school girl with no money. I know that you need people to pay you guys for premium but there are other ways to make money. Good app though.
