"Moon Clock" is an application for computing the moon phases, moon age,rise, set and culmination times for the sun and the moon as well as local sidereal time. Further, "Moon Clock" is useful for star watching since it also computes twilight beginnings and endings plus rise, set and meridian transit times for all planets from Mercury to Neptune. Two language versions are available, Japanese and English.
Observation locations can be picked from a world map, or freely set by input of longitude, latitude and altitude, while geographical coordinates can as well be retrieved from GPS. What is more, clock color schemes and fonts are selectable to taste from preset patterns.
