Earth & Sky Explorer
AR Compass: Earth, Moon, Sun
$2.99 · Designed for iPad. Not verified for macOS.
A precision tool for curious minds. Explore Earth and sky, track the Sun & Moon, see the ecliptic and celestial equator, look beyond the horizon, see through the Earth.
"Earth & Sky Explorer" brings this to life in a unique and intuitive way. A beautiful 3D compass with precise GPS data lets you see through and across the Earth, and visualize Sun & Moon paths and key celestial lines in AR — for your location, or in VR for any place and time.
No ads. No tracking. Just a powerful tool — for the price of a nice cappuccino.

Notes:
Not all iPads are equipped with GPS receivers.
Even in the age of GPS, the compass is still based on measuring the Earth's magnetic field.
This measurement can be affected by magnets in the phone case or by other magnetic or electrical objects nearby.
Stay curious!
