Moon phase & lunar calendar
Every day carries its real moon phase, the Moon's zodiac sign to the arcsecond, and how fast it's moving. Scroll back through any month, or forward to the next Full Moon.

Mood patterns & charts
Once you've logged enough days, LunarLog looks for the shape of them: your best and hardest moon sign, how each phase tends to find you, whether sleep and steps track with how you feel.

Sleep tracking with the lunar cycle
LunarLog reads sleep and steps from Apple Health and sets them beside each logged day — so "I slept badly and the Moon was full" stops being a feeling and starts being data.

We tell you the truth, even when it isn't the Moon
Most moon apps are built to agree with you. LunarLog ranks every influence it measures — sleep, steps, moon phase, moon sign — and if the Moon comes last, it says so. Sometimes the honest answer is that your days find their own weather. That's still worth knowing.
