To help you plan outdoor activities like hiking, hunting, fishing, and photography, this app displays the current locations of the sun and moon in the sky. A time slider lets you animate the sun and moon to see where they will be at any time of the day.

The application also allows you to calculate the positions of the sun and the moon and their rising and setting times for any location and for any date, as well as the nautical twilight times and illumination of the moon. If you know the RA and Dec of stars or planets, you can also enter them to find out where they are currently in the sky.

In addition, you can also choose to generate a forecast table of the sun or moonrise / sunset times and illumination for a given date range.

A compass page is also included to help you orient your phone to find the current position of the moon. (The compass page requires your phone to have a magnetic field sensor).
