About Lunalog

Lunalog is a mood, and energy tracking app built around one idea: you, and the sky above you, run on the same rhythm. Each day you can log your flow, symptoms, moods, energy, and a few notes, and Lunalog quietly records the moon's phase, its illumination, and its zodiac influence for that date. Because the two are kept side by side, you can look back and see patterns: which moods tend to show up around a particular phase of the moon, which symptoms cluster in which zodiac sign , and how your energy shifts across the month.

Lunalog is for anyone who feels drawn to lunar rhythms. That includes people who have been charting their cycles for years, people exploring cycle syncing for the first time, and anyone who simply wants a private place to note how they feel each day. You do not need to believe in astrology to use it. The lunar layer is a lens for reflection, not a medical tool: Lunalog makes no diagnoses nor claims about fertility, and it is not a form of contraception.

Lunalog is designed and built by a woman-led, small independent team, not a medical company nor a data broker. We keep it deliberately simple: your entries are private to your account, logging takes a few seconds, and every pattern you see comes from your own data. There are no ads inside the app and no selling of personal information, ever.
