Astro Info is an astronomical ephemeris/almanac for PalmOS. It displays some basic information useful to stargazers, such as rise, trans, and set times, coordinates, magnitude and phase information for Sun, Moon, and the other 8 planets and stars. It can display a view of the sky (with stars, the Sun, Moon, and planets positioned) at arbitrary times and locations. You can also search for objects based on their names and see where they are.
MarsClock is designed to aid engineers, astronomers, Gods of War, Hrossa, and specifically mission controllers for the upcoming NASA MER and ESA Beagle-II missions to Mars. It converts to and from Earth time (Local and UTC) and Mars time (Local Mean Solar Time and Local True Solar Time) for any location.
