Real astronomy, not vibes
Phase, illumination and sign come from standard astronomical algorithms and are computed on your device. The moon you see is rendered from NASA's lunar map with the terminator in the right place — not a stock crescent.
On the App Store
Moon-chi tells you what phase the moon is in, what it means today, and what to actually do about it — in plain language, without the incense-and-mysticism voice. No account. No email. Works on a plane.
Free to download, on iPhone and iPad. The phase tracker, the moon calendar and the sky itself are free forever. Readings are $0.99 each, or included with a subscription — which also unlocks the journal, your natal chart and the oracle.
Why it's different
Moon-chi has no accounts. There is no sign-up screen, no password, no verification email, and no "create a profile to continue." You open it and it works.
Your birth details and everything you write stay on your device. The natal chart is computed on your phone, not on a server. Even the birth-place lookup uses a city list bundled inside the app, so it never asks for location permission and never reads where you are.
The moon is the one thing in astrology you can independently check. So the math had better be right.
What you get
Phase, illumination and sign come from standard astronomical algorithms and are computed on your device. The moon you see is rendered from NASA's lunar map with the terminator in the right place — not a stock crescent.
Short, direct, specific to the phase and your chart. No "dear one", no "the universe whispers". Something you could actually do before lunch.
A full birth chart on a hand-drawn celestial wheel, Sun through Pluto, with every placement and aspect interpreted. Generated once, then yours.
Log mood, energy and intention against each phase. Over a few cycles it starts showing you your own patterns instead of guessing at them.
The app



How it works
Date is enough to start. Add the time and place and you unlock your rising sign and the full chart — both computed on your phone.
Today's phase, how lit it is, what sign the moon is in, and a reading written for that combination. Roughly a minute to read.
Mood, energy, an intention. The calendar fills in behind you, and the patterns show up on their own after a cycle or two.
The oracle is a conversation about your chart and the current phase, rather than a horoscope you read at. It's the one part that needs a connection.
