GraphNCalc83 App Reviews

A good app overall except for the solver. It can give incorrect answers. I tested it against a problem with a known answer. My real 84 got it right. The solver on this app was way off.

Really impressive app!

I am learning to use this type of calculator and this app follows standard layout and function. Nice interface. Great function.

I bought this app during the pandemic year and have been gladly using it to teach. Best purchase ever! The service provided is wonderful too.

This calculator has helped my kids throughout high school and now into college. I never had statistics, so this app is a godsend to them. Love it!

I've had this app for a while but didn't realize until a day or two ago how superior the graphing is in so many ways (e.g., pinch zooming, f(x,y) mode, and the magnifier). It's well worth the cost, *far* less then the cost of a calculator (and the developer deserves a lot of credit for making the app free during the height of the pandemic). Some time ago I discovered a minor bug and wrote to the developer, who fixed it almost instantly and was very gracious.

It’s just insane to think I have a fully functional graph Calc on my phone. Mind blown. Just awesome and kudos to the developer.

Love the calculator and all of its functions! Saved me from last minute problem solving that my TI-84 wasn’t able to perform. Excellent and extremely useful.

I used this going through my CM Program in some pretty intensive classes and have used it throughout my career calculating all kinds of things. it’s a no nonsense calculator app that pretty much allows you to turn your phone into a graphing calc. It’s worth the download and i have repeatedly turned to this calc for all kinds of things over the last 6 years or so.

I’ve been using this app for years. Great to have a graphing calculator in my pocket that works like the one I’m used to! I really appreciate the updates to support the new iOS.

You might not be allowed to use this app on a test, but it is as functional as any standard graphing calculator out there. The developer has done a good job implementing all the features and even enhancing the experience with the phone touchscreen. It is not buggy or slow, and the design is well thought out. There is no drawback to this app. I wouldn’t go back to a real graphing calculator, though a graphing calculator has real buttons. I use this app all the time. For me it is worth the investm

If you like TI83 you will love this app.

Great alternative to buying a $100+ TI-Series calculator, got me through online class during… uncertain times, with minor differences in menus and functionality. Really nice that the developer made it free during said uncertain times as well. Many thanks!

Use it almost daily very convenient to be built into my iPad. As an engineer I am constantly in need of a calculator and the more capability it has the better off I am. I am also a retired math, teacher, and adjunct professor, and I recommend this product greatly to my students as a low-cost alternative to purchasing a a graphing calculator, and, of course, having the capability to use it at any time. This product is worth every penny you may pay for the app, and then some don’t hesitate to buy

Very handy technical calculator. Graphics work great!

Does everything you need. Love this app!

This app is everything the professor is excited about. Brilliant . Love the structure and features that reassure one that the keys are active. Good solid screen images. Can’t say enough about the app. Very affordable for Student and professionals alike

This app is the bomb. Got me through stats with flying colors and saved me a ton of money, not having to buy a graphing calculator. Highly recommend!

Don’t waste your money on some random calculator!

I have looked for a useful scientific calculator with superior graphing. My son showed me the recommended app for his college statistics course and that is how I came to use GrafNCalc83. I primarily used HP in college, but after using the GrafNCalc83 app on my phone i have become much more comfortable and it is my go to app for mathematics. -rm2271

Still the best emulation of TI’s flagship calculator.

Ever since a professor asked us to use this for her class I haven’t used any other calculator (app or real world.) can perform so many functions and so easy to use. I don’t even use the calculator that comes preinstalled on iPhones anymore because I prefer this one and find it more user friendly even for basic equations

Love this app. Super useful for me

I use this with my students, because I can take a screenshot to show them what to do. Much easier than a long explanation!

It's perfect; just like having a ti-83 Plus anytime you need it. It's super convenient.

Perfect to use on my iPad and iPhone to quickly crunch some numbers for my engineering classes.

I love how how the graphs scroll and glide when you flick your finger across the screen. I haven't seen any other app do this- amazing!!!! Makes the TI calcs seem positively Stone Age.

I am a high school math teacher and this calculator is sweet!! It does everything and is touchscreen. Just like TI-83 and TI-84. Worth the price!!

This is the best TI calculator app!

I strongly recommend this wonderful calculator. You will not regret. The best of the best calculator

I have used this consistently throughout the past years. It is always with me; therefore I am never muttering to myself that I wished I had my graphing calculator with me. It was a great buy!

Familiar powerful layout, it’s my go-to for any number crunching.

I have a visually disability, so being able to download a Ti-calculator with larger keys is so life changing. This is so beyond helpful and has assisted me for years. Thank you to the creators and developers.

I could never go back to a calculator.

This app converts your phone into an enhanced, much faster version of the TI-83+ in a very compact binary. Runs and debugs BASIC programs. Developer makes periodic updates to add new features. Outstanding job!

This is actually one of the best apps I have ever seen. It is a beautiful app. I love it.

In addition to this being an excellent emulator for a TI-83 or 84, when I reported a small bug Ernie responded to me in a matter of hours and had a fix available within a few days. You can’t ask for much better than that.

Great emulator of Ti83 and free updates!!

Amazing app, been using it for years!

I actually think this is better than any of the ti-83/84 calculators. All of the functionality is there, there are some built in apps, and the graphics are better. Very well done, and much cheaper than the calculators.

I highly recommend this calculator. I'm always trying new calculators and this is, so far, the best.

How do I set up a frequency table on the calculator?

I have all my students download this app. It gives them a free graphing calculator whenever they need one.

This is the only calculator app you need on you phone

And active with updates and improvements.
