How does Moondu calculate lunar data?

Moondu uses approximate on-device calculations for lunar phase and related information. The illustrations are artistic representations.

Is the guidance predictive?

No. Guidance is symbolic and reflective, inspired by traditional astrology; it does not scientifically predict productivity or events.

How do I enable reminders?
