Using the Compatibility Calculator

The Compatibility Calculator compares your birth chart with another person's to produce a synastry-based compatibility score and detailed analysis.

How to run a compatibility check

1. 1Tap the Heart icon in the bottom navigation.
2. 2Enter the other person's name, gender, date of birth, time of birth (optional), and birth location.
3. 3Tap "Calculate Compatibility".
4. 4Your results appear with an overall score and a breakdown by category (emotional, physical, intellectual, long-term potential).

Compatibility history

Every check you run is saved automatically. Tap "Match History" on the Compatibility screen to review past reports. This makes it easy to compare different people side by side.

What the score means

The score is a synthesis of multiple synastry indicators — how your Sun, Moon, Venus, and Mars placements interact with theirs. A high score suggests natural harmony; a low score doesn't mean incompatibility, just that the relationship may require more conscious effort.
