Where
Start with the map. Your birth chart, mapped onto the whole planet. Score thousands of cities for love, work, vitality, and growth, and compare places side by side. Planning a move, a trip, or a fresh start? Find the ground that backs you.
When
Daily cosmic weather, moon phases, and the transits actually touching your chart. Zoom from today out to the year. Catch the windows worth using and the ones worth resting through.
Ritual
Guided practices for each moon phase. Small ways to mark a threshold instead of letting it pass unnoticed.
Together
Add a second chart for couples mode: synastry, composite, and the places that hold you both. Or go wider with group mode for three to six people.
The astronomy is real, computed from a built-in engine, not a borrowed API. Astrology here is for reflection, not prediction. A way to read the weather, not a forecast you have to obey.
