AXIOM
AXIOM
Four modes — basic, scientific, programmer, conversion — share one window. Every result you compute is searchable, recallable, and never leaves your device.
Switch from the dropdown in the top-left at any time. Axiom remembers what you used last.
Every detail is in service of the calculation in front of you.
Expressions evaluate with proper precedence. Parentheses, powers, and operator priorities behave the way you learned them.
Every result is saved with its expression, mode, timestamp, and notes. Tap to recall — Axiom even switches modes for you.
Every operator and digit is bound. ESC clears, Enter equals. Power users never reach for the mouse.
Length, mass, temperature, area, volume, speed, time, and data. Two-way, no equals key required.
Follows your system preference, or pick a fixed theme. Persistent across launches.
64-bit integer math with bitwise operators. Live readout across decimal, hex, octal, and binary.
No telemetry. No analytics. No cloud. No accounts. No advertising. Axiom never makes a network request unless you click a link in About — and even then, it just hands the URL to your browser.
