Synastry: Relationship Charts

Bring two birth charts into one comparison. Synastry explores the planetary contacts, lunar nodes and house overlays between partners, friends, family or colleagues. Read each person's role in the interaction and explore a modern midpoint composite.

SAVE AND COMPARE BIRTH PROFILES
Enter a birth date, local clock time and place. Search for a city or enter coordinates, choose the time zone, then save your profiles. Keep two people selected, switch pairs or swap A and B.

READ THE ACTUAL CONTACT
Explore 525 original aspect readings covering planets, lunar nodes and timed angles. Each combines a specific pair dynamic, the meaning of the actual aspect and a practical reflection. Same-planet contacts have one shared reading, while mixed contacts identify each person's role.

Compare conjunctions, sextiles, squares, trines and oppositions, with position readouts and contact orbs. Choose ten planets or the classical seven. A gold-and-silver zodiac wheel keeps both charts visible, with separate bands and position leaders for crowded symbols.

NODES, ASCENDANT AND MIDHEAVEN
Choose true or mean lunar nodes. Explore the South Node's modern karmic and familiarity themes and the North Node's direction of development. Ascendant and Midheaven contacts are included for each person whose birth time is known.

HOUSE OVERLAYS IN BOTH DIRECTIONS
See where A's planets fall in B's houses and where B's planets fall in A's. Choose among six house systems and compare the two directions with their own descriptions.

THE MIDPOINT PATTERN
Explore the shorter-arc midpoint chart for planets and lunar nodes, with its own zodiac wheel, positions and aspects.

LEARN THE METHOD
Nine original Lore articles explain the luminaries, aspect language, house direction, lunar nodes, timed angles, composite technique and working with an unknown birth time. A home-screen widget shows your selected pair and closest chart contact.

When a birth time is missing, select the unknown-time option. That person's Moon and angles are omitted, and house overlays need both times. The remaining planets use a noon reference. Enter a known time as the local clock read it and check the place and time zone.

Chart calculations run on your device and the reading library is bundled with the app. Profiles are saved locally. The app also includes advertising, Play billing and external support links.
