## About

Numeral X reads Roman numerals off things. Point the camera at a clock face, a cornerstone, a film credit or the title page of an old book, and it finds the numerals in the picture and converts them.

— WHAT MAKES NUMERAL X DIFFERENT —
• The camera does the typing
  Pro recognises text in a live capture or a photo, picks the Roman numerals out of it and converts them, so nothing has to be transcribed by hand.
• Five hundred at a time
  Pro converts a range written as 1-500, or a pasted list, in a single pass.
• Clock-face numerals
  A toggle switches to the additive spelling that clocks actually use, where four reads IIII rather than IV.
• Numbers well past 3,999
  The overline notation is supported, so values up to 3,999,999 convert properly instead of stopping at MMMCMXCIX.
• Dates as well as numbers
  Convert a year on its own, or a full day, month and year together.

— PRICING —
Included: live two-way conversion, the clock-face toggle, the extended range, the date converter and your last five conversions.
Numeral X Pro is a one-time in-app purchase, never a subscription. It adds camera and photo scanning, batch and range conversion, and unlimited history with export.

— FEEDBACK —
Made by a small indie team. Email obeliskclubclub@gmail.com with feedback, bug reports, or feature requests.
