## Calc Engine Description
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.
