Suntimes is an app that allows you to get various useful information about the Sun and the Moon, like the direction from the geographic north, and the height above the horizon of the two objects.

The main graph shows the heights on the horizons of the Sun and Moon during the day. The app also provides other useful data such as the rising and setting times of the two objects, the sunrise and sunset times as well as, for the Moon, the illuminated fraction of the disc (also represented graphically) and the current phase.
