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. Table: Analyze functions using the table viewer. Use the split screen mode to simultaneously view a graph and table. Matrix and Lists: Matrix and list editors and a full set of matrix and list operations are built in. Unit Converter and Constants: Convert between a wide variety of scientific, engineering and common units. A large set of physical constants are also included. BASIC programming: Create, edit, debug and run BASIC programs. Programs run more than 500 times faster than traditional calculators. Import and execute .83p and .8xp files. Chemistry: The calculator includes a full featured periodic table, a mass calculator and a data base of element properties. The touch interface allows you to view and interact with the periodic table to view by series, state, melting point, boiling point, electronegativity, electron affinity, valence, ionization, radius, hardness, modulus, density, conductivity, heat and year discovered. Geometry: The geometry application computes perimeter and area for a variety of 2d geometric figures including squares, rectangles, parallelograms, triangles, polygons, circles, arcs and ellipses. A full triangle solver and interactive unit circle grapher are built in. Solve line intersections, project a point to a line and find a circle given 3 points. Finance: Compute time value of money problems including annuities, lump sums and uneven cash flow analysis with IRR and NPV Built-in user guide: A user guide is included and is a touch away using the ? key or ⓘ on any menu. All functions have a full manual page with description of arguments and examples of use. Pop up bubble help displays function arguments during problem entry and program editing.

I have been looking for a truly powerful calculator for a long time. I've tried variations of the HP top of the line and several were very nice but as I said in one of the other reviews that calculator emulators are great for what they are but the idea is to serve your needs. If a calculator still retains all of the disadvantages of the original then it is not an advancement. This calculator not only provides all the capabilities of the HP that inspired it but also eliminates many of the physical calculator's cons. Ever had a calculator that did everything you needed and more but required a book and a lot of memory work to do any of the sophisticated things? This one does not have that drawback. There is context based help available at the touch of a button. Now you can actually use the full power of the calculator without it becoming a research project. To me, that essentially made the more advanced the calculator the less useful it became. Not so here. I applaud the developer. We don't need exact replicas of calculators, we need something to do a job with the least effort on our part. This is a giant step in that direction. Calculators are not sacred but my time is. Get this. You won't regret it. Now I can get on with my work!
I am giving this 5 stars because compared to purchasing a ti-84 it is fantastic. A ti-84 is around $120 while this is only $6. We have ti-84s at our school and I prefer those because of the buttons being easier to use and press but they can do much about that because this is a touch screen phone. The one flaw I have found while using this is while zooming in closely to a line on the graph sometimes the line will move or extend a bit while I am zooming in then it will change positions when the zooming stops. I was graphing circles and just messing around with the app when I noticed this. I put y1=-sqrt(64-x^2) and y2=sqrt(64-x^2) and I noticed as I zoomed in to where they should presumably meet along the X axis they were messing up for me. Otherwise amazing app and I believe they actually have more features than a brand new ti-84.
Hello, I’ve been using this app for 4(?) or possibly even 5 years now. It’s the best app I’ve ever downloaded. I don’t think I would have been able to get through Calc BC without it because I couldn’t see a regular Ti-83 well enough. If I could give it more stars, I would. Most of the time, it’s far better than Desmos. Being legally blind, and having the capabilities to do complex math is a life changer. Only thing that sorta bugs me is the splash screen and app icon because if a teacher is peaking over my shoulder they may believe me to be goofing off (happened a few times) because my original iPad Air takes forever to load it (I’ve been looking at an iPad Pro for the bigger screen but they are way too expensive. Well anyway, thanks to the developer for literally changing my life. I appreciate it.
Ohh yess....did I mention the chemistry and Environmental engineering utility! From personal experience this is an ample scientific calculator that can get you through graphing, and bio-statistics,and physics. You will never misplace it, as it is on your tablet and smart phone in a pinch. The programmers care about your user experience, readily offering tips and promptly answering troubleshooting/ how to use the functions. The built help menus are unparalleled. This is one app I won’t be deleting to free up space! Also I think the user interface is extremely intuitive and rich with extras that you simply don’t get with all the handheld calculators that it replaces. Lastly it actually works natively smooth as if it belongs in iOS on your device screen.
PERFECTLY DESIGNED AND IMPLEMENTED GRAPHING CALCULATOR!!! Best app ever, best graphing calculator ever -- bar NONE!!!! I cannot believe I have been hauling around my bulky "ti 84 plus c silver edition" (for 2 years) when I could have been using this app. i cannot believe I have taken five junior college math courses (int algebra, trig, precalc algebra, nature of math, finite math) and no one has told me about this app. I cannot believe I have suffered with not being able to easily see/know window mins/maxs and have labelled tick marks while looking at "graph." This app is what the physical ti graphing calculator SHOULD be doing, but cannot, because ti graphing calcs dont have a touchscreen like our smartphone!!!! With this app and the wolframalpha app, I can do anything. (Please make a CAS calculator, too!) I wish i could give the rating of INFINITE stars...
