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. [Top of Screen] MOON: Moon phase (lunar age 0–29) HOURS: Hours (24-hour cycle) MINUTES: Minutes (60-minute cycle) SECONDS: Seconds (60-second cycle) [Center of Screen] The year, month, date, hour, minute, day of the week, and second are displayed.

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. [Bottom of Screen] LATITUDE: Latitude (−90° to +90°; positive values indicate north, negative values south) LONGITUDE: Longitude (−180° to +180°; positive values indicate east, negative values west) COMPASS: Direction of north LEVEL: Level, measured along the iPhone’s X and Y axes Choose from four background colors: Space, Midnight, Twilight, and Sky Blue.
