A full graphing calculator with the layout and feel of a classic handheld — built for iPhone and iPad. Plot up to 9 equations, run TI-style programs, solve systems, fit regressions. No ads, no subscriptions, no internet required. GraphCalc 84 is the classic graphing calculator, rebuilt for your phone — complete, faithful, and fast. If you know the TI-84, your muscle memory works on day one. Graph everything. Function, parametric, polar, and sequence modes with nine equation slots, trace, tables (Auto or Ask), zoom — including ZoomStat — and full window control. Find zeros, minima, maxima, intersections, derivatives, and integrals right from the CALC menu. Statistics, complete. Every hypothesis test and confidence interval — Z, T, 2-sample, proportions, χ², χ²-GOF, F, LinRegTTest, ANOVA — plus 1-Var/2-Var Stats and 13 regression models with TI-accurate quartiles. Visualize with scatter, xyLine, histograms, box-and-whisker, and normal probability plots, and shade distribution areas right on the graph. Real fractions with ►Frac/►Dec and mixed-number display. Number bases from binary to hex with bitwise operators. Your AI tutor (new in 1.7). Long-press any answer — or any error — for a clear step-by-step explanation. Ask for worked steps when a problem is beyond the built-in solver. Have your graphs described in plain language, from intercepts to asymptotes, computed by the calculator and narrated by AI. All AI features are optional: bring your own Anthropic API key, keep it securely on your device, and send nothing until you choose to. Without a key, GraphCalc 84 remains complete and fully offline. Exact where you want it (new in 2.0). Switch ANSWERS mode to Auto and results stay mathematically exact — fractions, simplified radicals, multiples of π — with ►Dec one press away. Four symbolic commands bring real algebra: simplify, expand, factor with exact roots, and derivatives. Prefer decimals? Everything stays exactly as it was until you opt in. Programmable. Write and run TI-BASIC programs — control flow, input/output, and the complete DRAW command set, down to reading pixels with pxl-Test(. Beyond the original. A physical-units engine with dimensional analysis. Math Snap: point your camera at a problem, or write it by hand. A hub of 22 built-in apps — solvers, periodic table, physics constants, curve fitting, date math, and more. Twelve accessibility-tested themes, with a free web editor to design your own.
