Calc Engine vs Construction Calculator ۬

Calc Engine™ — The Calculator That Fits How You Work Whether you're splitting a dinner bill, plotting an equation, or working through bitwise logic, Calc Engine meets you where you are. It's a beautiful, fully customizable calculator that grows with you — and syncs seamlessly across iPhone, iPad, Mac, and Apple Watch. Make it look and feel like yours • Choose from rich color themes to match your style • Pick the fonts and key shapes that feel right in your hands • A calculator you actually enjoy opening Design keyboards your way • Build your own keyboard pages — drag any key from a curated library onto a 4×5, 5×5, or 6×5 grid • Mix digits, operators, scientific functions, your own constants — anything you reach for often, all in one place • Set a long-press alternate on any key so a single tile handles a primary and secondary action • Name each keyboard, pick its icon, and reorder it alongside the standard pages — your custom keyboards show up right where you'd expect them • Enable or disable any page (built-in or custom) per device Build your personal math library • Define your own functions with up to three parameters — name them whatever makes sense to you • Save the constants you use all the time and insert them with a single tap • Full calculation history, automatically saved — scroll back anytime Powerful math, always within reach • Trig (radians or degrees), logarithms, exponentials, roots, and more — there when you need them, out of the way when you don't • Live results as you type, so you always know where you're headed • Per-function rounding built in — perfect for money, measurements, or anything that needs a clean output Convert between hundreds of units in seconds • Tap a value, then any two units to see the conversion live — miles to km, lb to kg, °F to °C, gal to L, anything you need • 250+ built-in units across 40+ categories: length, mass, volume, temperature, time, speed, angle, energy, power, pressure, electrical, magnetic, optical, radioactivity, data, and more • Favorite the categories you actually use so they sit at the top — synced across your devices automatically • Build your own functions with conversions baked in — define a formula once and reuse it forever See your equations come to life in graphs • Plot equations like x = y² or sin(x) live as you type, right beside the keyboard • Tap any graph to expand into a full-screen view for closer inspection • A dedicated graphing keyboard with x, y, and = keeps everything in one place — no separate app, no separate mode Solve equations as you type • Type x² = 121 or sin(x) = 0.5 and Calc Engine finds every real answer • Tap the solved answers to reuse it in your next calculation, no separate "solve" mode Programmer mode without leaving the calculator • Type hex (0x), binary (0b), and octal (0o) literals — read and write the way you read code • A full bitwise toolkit: AND, OR, XOR, NOT, shifts, and rotates • Every result shown in HEX, DEC, OCT, and BIN simultaneously, with configurable word size (8/16/32/64) and signed/unsigned interpretation • Tap the binary row to expand into a byte-by-byte view with bit-position labels Private by design • Everything syncs through your personal iCloud — nothing stored on our servers • Fully localized and native on every Apple platform Unlock Calc Engine+ for the full experience — custom themes, fonts, key shapes, custom keyboards, user-defined functions, saved constants, unit conversions, live graphing, equation solving, programmer-mode hex/binary/bitwise, and more. Everything that makes Calc Engine truly yours. Teach it your formulas once. Customize it to feel like home. Use it forever.
