HexCalculator 2.0 — the programmer's calculator, rebuilt. • Operator precedence with parentheses: 2 + 3 × 4 = 14, (2 + 3) × 4 = 20. The whole expression is shown as you type and the result appears on =. • New bit tools: POP, CLZ, CTZ, byte swap, bit reversal and bit-field extraction. • IEEE 754 view: see any value as Float32/Float64 (sign, exponent, mantissa) and convert decimals to bit patterns. • Insights: Unicode characters with UTF-8 bytes, RGBA colours and data sizes. • Home and Lock Screen widget with your last result in every base. • Siri and Shortcuts: "Calculate" applies arithmetic or bitwise operations to two numbers. • Full hardware keyboard support on iPad, including AND/OR/XOR, shifts and parentheses. • Now in German, French, Italian, Portuguese, Japanese and Chinese. • Fixes: octal backspace, paste respecting the word size, multi-base display in unsigned mode, landscape keypads for DEC/OCT, history export.

The biggest update yet — and the calculator is now completely free. • Binary base unlocked for everyone, plus a new octal (OCT) base • Word sizes: 8, 16, 32 and 64 bits, with signed/unsigned modes and overflow detection • Interactive bit grid — see every bit, tap to flip them (Pro) • New operations: MOD, NAND, NOR, ROL, ROR, NOT • Operation history in all three bases, with unlimited history and export in Pro • Long numbers now scale to fit the display • 6 new alternative app icons (8 total, Pro) • ASCII & RGB insights for the value on screen (Pro) • Siri & Shortcuts: convert numbers without opening the app • Haptic and sound feedback, full Spanish localization, redesigned landscape layouts • Restore Purchases and a new tip jar — thanks for supporting an indie developer!
