NibbleCalc: Dev Calculator

About NibbleCalc: Dev Calculator

What's new in 1.3 • NibbleCalc is now completely ad-free. CALCULATOR • Operator precedence: 2 + 3 × 4 now equals 14 (powers first, then × ÷, then + −). • Scientific panel (landscape): memory keys mc, m+, m−, mr, plus a 2nd key for roots, log base y and inverse hyperbolic functions. • Hardware keyboard support, great on iPad. PROGRAMMER • New keys: MOD, >>> (logical shift right), ROL / ROR, BSWAP and ⌫, plus an int / uint switch. • Bit Grid: swap the keypad for large bit keys, and drag along a row to set or clear several bits at once. • Easier to read: grouped digits with faint 0x / 0o / 0b prefixes, binary wrapped every 32 bits, and the pending operation shown at the top. • Touch and hold a value to copy it with or without prefix and separators. • IEEE 754 float view for 16, 32 and 64 bits, with sign, exponent and mantissa in color (Pro). COLOR • OKLCH color space, transparency (alpha) and more HEX formats (#RGB, #RRGGBBAA, 0xAARRGGBB). • Export to CSS hsl() and oklch(), Tailwind, Android XML and Compose / Flutter. • Photo Colors: find the main colors of any photo (Pro). • Harmonies with a color-blindness preview (Pro). DEV TOOLS (Pro) • New JSON formatter and validator that points to the exact line and column of an error. • New Regex tester with highlighted matches and capture groups. • Clearer input fields with Paste and Clear buttons. DATE, TIME & DATA • Timestamps in seconds, milliseconds, microseconds and nanoseconds, with the unit detected from the number of digits. • Several time zones side by side. • New Data Size mode: see exactly how GB, GiB and Mbit differ (1000 vs 1024). ACCESSIBILITY • VoiceOver labels for every key and slider. • Text follows your Dynamic Type size. FIXES • If you bought Pro, your theme, mode and 128-bit setting are no longer reset when you reopen the app. • Layout fixes on iPhone SE and in landscape, plus many other improvements.
