Planet is a cross between an atlas and a world clock, with a few other things such as moon phase and sun position thrown in. Planet was inspired by the clock application on my old Psion 3a. Thanks to Psion for a great product; I still miss their presence in the handheld arena.

At the heart of Planet is a scalable map of the world showing night and day and hundreds of cities from a user customizable database. One of these cities is designated as the home city, and its time and date will always be shown at the bottom left of the screen. Tapping on other cities in the map window will select them to view the local time and date, sunrise and sunset times, and distance from the home city. Planet can also search through its city database in response to a Palm find, as a rapid way of locating cities or countries.
