Store description excerpt
Vinculum is a fast, fully offline roman numeral converter for anyone who needs an accurate translation between numbers and roman numerals — students checking homework, film buffs reading copyright years in movie credits, and couples engraving a wedding date as MMXXVI. Type a number and watch the roman numeral appear instantly, or type a roman numeral and see its number — both fields update live, with no convert button to tap. A clock-style toggle switches between the standard subtractive form (IV) and the older additive form seen on clock faces (IIII), and the engine handles numbers all the way up to 3,999,999 using proper vinculum (overline) notation for anything past the usual 3999 ceiling — most converters simply stop there. The dedicated Date tab turns any birthday, anniversary or wedding date into roman numerals — as a year alone or a full day.month.year — ready to copy for an invitation, a tattoo, or an engraving. Unlock Pro for batch conversion (turn a whole range or list of numbers into roman numerals in one pass), on-device camera scanning that reads roman numerals off a clock, book, or monument using Apple's Vision framework, and unlimited searchable history with export. Vinculum runs entirely on your device: no account, no ads, no data collection, no internet connection required.
