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. Earth completes one circuit around the center of the screen in 365 days (366 in a leap year). The display uses Earth’s axial tilt to approximate the amount of daylight at that time of year. 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.

Verdict
The clearest difference is rating: Level at 4.4 against Spacetime Clock's 2.8. Level also leads on review sentiment (80% vs 41%) and monetization model (free vs paid). Spacetime Clock's advantage is update cadence (every 2 months vs every 6 months). On price, ads, in-app purchases and device support there is nothing between them.
