Field notes

Ten Thousand Skies models the changing north celestial pole as Earth’s axis slowly wobbles, allowing a selected location to be viewed across dates from 10,000 BC to AD 10,000. Its Logbook includes Göbekli Tepe, the Great Pyramid, and Kennedy Space Center before Apollo 11, while a separate layer covers all 88 constellations and available star-catalog details. The homepage says the iPad app will work offline with no account, ads, analytics, or network connection.
