HexCalc: Programmer Calc

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.

Fully offline, no account, no ads, no tracking. Pay once and keep…
