Numeral XScan numerals with the camera

Version 1.0 · Updated

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.
