Your cycle, beside the real Moon

Wooly learns your own rhythm — not a textbook average — and tells you which of your four inner seasons you are walking through today.

✦ This stays on your device. Your dates, your symptoms and your notes are written to this browser only. They are never sent to Magical Chart, never stored on a server, and nobody — including Wooly — can read them. Clear your browser data and they are gone for good.

Not a medical tool. Wooly estimates from your own past cycles. This is not contraception, not a diagnosis, and not a substitute for a doctor. If something worries you, please ask a real one.

When did your last period start? How many days did it last? — optional

One date is enough to start. Wooly gets more accurate every time you add another.

How are you today?
