Sunfall, a Pocket Sky Almanac

Field notes

The app organizes daylight and moon information as a draggable 24-hour ribbon, with the solar path flowing into the lunar one. It supports any place and date in that location’s local time, and includes bearings for photographers who need to know where light will arrive rather than only when. The site says calculations use NOAA solar-position methods and standard lunar theory, with validation spanning ten cities from the equator to Anchorage.
