ezAlmanac Pro is a fully unlocked version of ezAlmanac which generates Nautical Almanac pages from 1961 to 2059 for one low price.

Just Added !!! New export function allows you to export whole sections of the Nautical Almanac to a PDF file or print directly to a wireless printer. No need to ever buy a printed Nautical Almanac again. Just print the pages you need to have a paper backup before making a passage!

Please check out for a full description of the application and in-app help pages.
