Compatibility
The angles are calculated,
not guessed.
Two birth charts are set side by side. The angles between the planets are a real calculation — that part is astronomy. The reading starts after it.
Outer ring — your chart
Inner ring — their chart
Lines — the angles between them
The planet glyphs are drawn as vectors here, as in the app. Written as characters, Android pulled some of them from the emoji font; a font can let you down halfway, a drawing cannot.
Read under four headings
Communication
What ground you stand on when you explain yourselves to each other. Mercury decides most of it.
Emotional rhythm
How closeness forms, and when it slips. This is where the Moon's angles look.
Attraction
What happens at first, and why. Venus and Mars are read here.
The long run
What gets easier with time and what gets harder. The slow planets speak here.
Don't know your
birth time? That's fine.
The reading works without it — and tells you plainly that the houses were left out. It never pretends to know what it doesn't. You pick your birth place from cities around the world; what is stored is the city centre's coordinates, not your location.
There is no compatibility score. A percentage tells you nothing, and people act on it anyway.
