GraphNCalc83 App DESCRIPTION

GraphNCalc83 uses touch, color and blazing speed to handle your math problems. The familiar calculator keyboard, arrow keys and functions are enhanced with full touch input for all graphs, editors and menus. Enter calculations in natural textbook format. Enter fractions and view result as fractions. Trace graphs with your finger. Zoom in and out with a pinch. Explore regressions with a tap on the screen. Scroll through the list, matrix and calculation history with a swipe. Tap the ? key for help. Written using the latest 64 bit math libraries, GraphNCalc83 harnesses the amazing computing resources of the iPhone and iPad to provide a colorful, fast and fluid experience. Graphs scroll, glide and zoom smoothly. Matrix, statistics and BASIC programs run 500x times faster than traditional calculators.

GraphNCalc83 includes:

Algebraic entry: Enter problems using full algebraic textbook notation. The command line editor includes interactive parenthesis matching and high lighting, undo and redo, bubble function help and a 200 level calculation history and recall stack. Generate a PDF report of calculations for mailing or printing using the SEND function.

Math functions: Trigonometry, logarithms, function minimum, maximum, numeric integration and derivatives, general solver, real and imaginary numbers, combination, permutation, random number generation, normal, T, chi squared, Fisher, poisson and geometric distributions, binary shift and rotate, test and logic operations, list operations including sort, std. deviation, sum, sequence, matrix determinant, transpose, sum, ref, rref, addition, multiplication.

Graph functions, parametric, f(x,y) and polar equations and statistics plots: Full color graphs with touch to trace, pinch zoom, function minimum, maximum, intersections, asymptotes and numeric integration. Output graphs in high resolution PDF format for mailing or printing. Interactively explore function behavior using variables tied to slider bars.

Statistics, Inferential Statistics and Distributions: A set of inferential statistics worksheets and graphs of distributions are included. The regression analysis screen allows you to quickly compute, view and analyze a data set using a variety of curve fitting methods.

Intended for use with TI-84
A MODERN GRAPHING CALCULATOR ON THE iPHONE 1. Fast, Interactive Touch-Screen Graphing 2. Everything is where you’d expect it to be 3. Scrollable Windows (no more spamming the up arrow keys) 4. Intelligent Error Messages 5. Convenient 6. IT’S FREE (for now). WHY MAKE ANOTHER GRAPHING CALCULATOR APP? 1. We (the creators), once relied on graphing calculators, and after installing countless, similar apps, we couldn’t find anything useable. Hence, we made our own.
 2. Before launching on the App Store, we personally worked with a limited, yet sizable, number of students to continuously improve the app. WILL IT REMAIN FREE? For those who use it now, it will always be free. However, eventually it will be monetized to ensure it’s sustainable for the developers. Regardless, we get it, not everyone can just buy things whenever they want. Hence why, even after release, we’ll constantly be trying to find ways to make it available to everyone.

wurbina

This app is in my opinion bitter than the actual calculator. The commands help is really helpful.!

Gabelim

This app is definitely better than the actual ti-83, 84, etc. I love it!

Jonesj26

I’m rediscovering my love of math, this calculator has been priceless in that journey. It’s amazing how much value you can derive from such an elegant piece of work.

ThomasSo..

I have looked for years for the perfect calculator app. I love the flexibility and that this is familiar design as TI series. I love this app! Just buy it! UPDATE: I continue to be impressed by this calculator. Just buy it!

notDaSti..

Does everything you need. Love this app!

kirbystk

Rounds all numbers to whole numbers, which is literally the worst things for data.

Ken

I can't count the number of other apps I have tried since 2010, but this one is the best. Keep up the great work! (4Q2019 update) This is STILL *the* calculator app that beats out all others. I wish schools would standardize on this app. (1Q2022 update) Still the best!

FrankyB1..

I cannot say enough about this graph calculator. When I needed one for my graduate statistics course I was bummed thinking what I would have to pay. When I saw this app I just knew it was too good to be true, and would never be like an actual scientific calculator. I was wrong! Not only is it beyond reasonably priced, it is the exact same as any handheld one. I even had my professor check it out and she loved it. Also, when I had some trouble figuring out how to use some options the creator responded to my questions within 24 hours, and explained it in “layman’s” terms that made it easy for me to comprehend. I love this app, it is well worth it.

Nancy

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!

cafaucet..

Perfect, cot-efficient option.

Mezoyodu

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

goreal

I teach statistics and I know that not all my students can afford $120+ for a TI calculator. They can use a class set that I keep in my claoom. I recommend GraphNCalc83 to them to use at home for their homework. This app does everything that the TI84 does. Sometimes I even use this instead of the TI84 during lectures. Also, I think it was wonderful that this app was available for free when the schools were closed during the pandemic. This really helped out my students during online learning. Thank you!!!

Jacob

This app is absolutely indispensable. It’s one of those apps that you forget you even have until that one time like once every few months or so where you absolutely NEED it and you need it NOW. And for those times, it’s perfect. It is EXACTLY like having a mini TI-83 / TI-84 with you at all times. This app is so unbelievably convenient!!!

andremei

I could never go back to a calculator.

biologes..

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

TrueBree..

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.

TechTren..

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!

mathamie

Super easy to use, the functionality of this app is hard to beat. Downloaded it when I was traveling and realized I’d left home without my TI84. This calculator not only saved the day but has since been my favorite go-to. Affordability that levels the playing field too. Thank you!

Shuffleu..

Amazing app, been using it for years!

BayAreaB..

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.
