01 / Why Lunolog
A calendar tells you the day.
A journal helps you remember it.
Lunolog brings lunar phases and calendar traditions into the same quiet space as your plans and personal notes. Explore the sky, record an experience, and return to it later — with room to form your own view.

04 / A note on perspective
Traditions can start a question.
They do not decide the answer.
Lunolog presents astronomical data and folk traditions. Cultural interpretations are not scientifically proven predictions, and the app provides no medical or financial advice. The decisions are yours.
