THE MONUMENT • The whole circle raised: thirty sarsen uprights and their lintel ring, the five great trilithons, the bluestone circle and horseshoe, the Altar, Slaughter and Heel Stones, the Station Stone rectangle and the fifty-six Aubrey holes — every stone carrying its Petrie number. • On real ground: the terrain is Salisbury Plain's own survey data, and the ridge the midsummer sun clears is the one that actually stands there. • Weathered sarsen and Preseli bluestone, damp courses and lichen, wind moving through the grass, torchlight for the dark hours. THE CALENDAR • The Wheel of the Year: solstices, equinoxes and the four cross-quarter festivals — Imbolc, Beltane, Lughnasadh, Samhain — each landing on the instant the sun actually arrives, not on a calendar date. • Moon phases, eclipse seasons and the 18.6-year lunar standstill, solved from the real ephemeris. • A time machine from 3000 BC to AD 3000. Watch Thuban hold the celestial pole for the builders in an age when Polaris was no use to anyone. • The sky over your own longitude, or over Wiltshire. HONEST ARCHAEOLOGY Every claim the app makes about the monument carries its tier — Established, Debated, or Modern tradition — with the sources one tap away. The solstice axis is established. The equinoxes at Stonehenge are modern tradition, and the app says so. Free to explore in fifteen-minute sessions. One purchase unlocks the clock and the calendar for good — no subscription, no account, no network, and no data collected.

SkyORB Classic Astronomy's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 17.0). On price and in-app purchases there is nothing between them.
