iYarrow pairs I Ching casting (the question in front of you) with Zi Wei Dou Shu natal charts (the life it's set against). Both free to try, no account needed. Casting isn't a button — sweep a live star field to fill an entropy pool, then touch three times to draw the hexagram (梅花易數 method, open-sourced separately, ~190 stars). Readings state both sides plainly — a frame to think with, not a verdict. Natal chart + full reading: $0. Credit packs only fund extra casts/chat beyond a free tier.
