G1RL vs Constructive Calculator

Math just got cute. G1RL is a real graphing calculator. Every TI-84 function you actually need, wrapped in themes that finally feel like yours. What it does: - Graph anything you can write: sin(x), 0.5x, cos(x*2), all of it - Real trig, logs, powers, roots, factorial, pi, percent - DEG/RAD toggle for trig the way you actually need it - Recent calcs strip on the calc screen so you can copy yesterday work forward - Full history log of every calculation - Girl Math toggle: tip and discount math the way it works in your head (10% off $50 = $45) Make it yours: - 4 free themes: Y2K Hot Pink, Bubblegum, Cotton Candy, Millennial - 5 premium themes: Y2K Mirror, Aqua Glass, Sunset Lava, Iridescent, Candy Shop - 5 premium key styles: chrome, liquid glass, lava lamp with heart blobs, charms, holo Pricing: - G1RL Pro Pass: $4.99 one-time.

What we do not do: - No subscriptions - No ads, ever - No accounts required - No data collection. Your calculations stay on your device. Made for anyone who wants real math AND a calculator that actually slaps.

Ordinary calculators round. Constructive Calculator doesn't. It computes with constructive real numbers, an arbitrary-precision engine that keeps every result exact and hands you as many correct digits as you ask for. The rounding errors that quietly accumulate in ordinary calculators simply never happen. AS MANY DIGITS AS YOU WANT A pocket calculator stops at about 15 digits and rounds off the rest. Constructive Calculator keeps every result exact, so the digits a normal calculator throws away are still there. Swipe √2, π, or any answer to pull in tens, hundreds, or thousands more, computed on demand. SCIENTIFIC KEYPAD Trigonometry in degrees or radians and their inverses, exponentials and logarithms, powers and roots, factorials, percentages, the constants π and e, and the standard normal distribution, its CDF Φ and quantile Φ⁻¹, computed to the same arbitrary precision as everything else. BIG INTEGERS, IN FULL 52! (the number of ways to shuffle a deck) prints in full, all 68 of its digits, with no scientific-notation hand-waving. BUILT FOR CLARITY A running tape of recent calculations, locale-aware digit grouping, and copy at whatever precision you need. Constructive Calculator is an independent port of Hans Boehm's constructive-reals calculator, rebuilt natively for iPhone and iPad.
