## What is HexCalc?

HexCalc is the programmer's calculator your phone always needed: hex, decimal, octal, and binary side by side, live, with real bitwise operations and a tappable bit grid.

FOUR BASES AT ONCE
Type a value and watch it appear simultaneously in HEX, DEC, OCT, and BIN. No mode switching — every representation is always live.

REAL BITWISE OPS
AND, OR, XOR, NOT, and left/right shifts, with selectable word size (8, 16, 32, or 64-bit) so overflow and sign behavior match the machine you're targeting.

FLIP BITS BY HAND
The interactive bit grid shows every bit in the current word — tap any bit to flip it and watch all four bases update instantly. The fastest way to build a mask or debug a flags field.

EVERYTHING ELSE TOO
Standard arithmetic, a history tape of your recent calculations, and a clean monospace keypad designed for thumbs.

Fully offline, no account, no ads, no tracking. Pay once and keep it next to your terminal forever.
