Every programmer needs to convert between hex and decimal. Check a bitmask. Do quick bitwise math. Different Calculators have a programmer mode buried in a menu, and it's clunky (or you switch browser tabs to a web calculator).
Hexa lives in your menu bar. Click it, type a value, see all representations instantly. Type expressions like 0xdead + 0xbeef and watch it evaluate live.
Native Swift. Native SwiftUI. Opens instantly.
- Menu Bar Native — Lives in your menu bar. One click to open, one click to dismiss.
- Live Evaluation — Type expressions directly:
0xff + 0x10,255 << 8,0b1010 | 0b0101. Results update as you type. - All Bases, All the Time — See hex, decimal, octal, and binary simultaneously. Use
