Our method and its limits

Three systems, one analysis

SoulResonance combines three perspectives into one profile: astrology (35 percent weight), Human Design (40 percent) and numerology (25 percent). Each system looks at a different layer. The weighting is a deliberate editorial choice, not a law of nature, and is shown with every analysis.

How we calculate

We compute all planetary positions ourselves, based on the astronomical models VSOP87 and JPL DE405. Your birth chart is derived from date, time and place, not from a sun-sign table.

Every change to the calculation engine runs against more than 1500 automated verification checks and 112 reference profiles. The same input always produces the same result: reproducible, consistent, verifiable.

To be equally honest: for highly time-critical edge values, such as the exact moment a planet turns retrograde, our models can deviate from professional ephemerides by hours. For daily impulses this does not matter; for minute-precise professional astrology, specialised tools are the better choice.

Where the texts come from

All interpretation texts come from a curated library of more than 2800 entries across more than 90 categories. They are editorially maintained and continuously extended. No interpretation is invented by an AI at the moment of your request.

The algorithm selects which text matches your constellation. The content itself is written and owned by humans.

What SoulResonance is, and what it is not

Important: SoulResonance is a tool for self-reflection. It does not replace therapy, medicine or professional counselling. In a serious crisis, please turn to professionals.

SoulResonance is:

• A tool for self-reflection: prompts that help you look at yourself and your relationships more consciously.
• A reference library: all core concepts openly explained in Knowledge and the glossary.
• Reproducible: the same birth data always produces the same analysis.

SoulResonance is not:

• Not a diagnostic tool: the analysis describes tendencies, not findings.
• Not a decision machine. Never base major life decisions on an analysis alone, ours or anyone else's.
• Not science: astrology, Human Design and numerology are interpretive systems with long traditions, but without scientific proof of effect. We do not claim otherwise.

Your data

SoulResonance runs on Swiss infrastructure and follows the Swiss data protection act (nFADP). The free calculators work without an account. Statistics are collected cookieless and anonymously, and only with your consent. Details in the privacy policy.
