Your backyard, or a famous spotting spot on the other side of the world, drawn on real terrain, skylines and weather, with the sun, moon, stars and planets where they really are. Every flight is in it where it actually is.
Turn your phone on its side while it charges and Skyarium keeps the sky going in the background. The Horizon directs itself, cutting to whatever's landing or taking off, between an arrivals board and a list of everything flying nearby. At home, a chime tells you a plane is about to pass over. Watching somewhere else, it keeps your time as well as theirs.
No subscriptions, no ads, no accounts, and nothing locked behind a paywall. Everyone gets the same Skyarium.
