Time, calendars, the movements and positions of celestial bodies, and direction are all closely connected. This app brings together time and place in one view. Alongside the time and date, it shows the phases of the Moon, Earth’s rotation and orbit, latitude and longitude, compass direction, and the iPhone’s level. It lets you see and feel where you are in time and space at a glance.

It does not show precise sunrise or sunset times. The Earth and Moon graphics change depending on whether your current latitude is in the Northern or Southern Hemisphere.
