What is here
The compatibility calculator scores a pair from two birth dates — it works out both signs itself — or from the signs directly when the exact dates are unknown. You get an overall percentage with a breakdown across five areas: love and chemistry, communication, work, everyday life and the long union. There is a table of all 144 combinations and separate readings for same-gender couples.
The relationship health test is 30 questions about the couple you already have. It scores trust, conflict, intimacy, boundaries and support from 0 to 100 in each area, with a partner comparison mode when both of you take it.
Three follow-up tests cover the narrower cases: warning signs of abuse, attachment style and red flags at the early stage.
The numerology calculator works from two birth dates without any zodiac signs: it reduces each date to a life path number, adds the pair arcanum from the destiny matrix, builds a Pythagorean square for both partners and factors in name numbers when you enter them.
The texting trainer is a scripted chat with an AI character: three personalities, five messages and a breakdown of the conversation with an interest score.
The BDSM test is the adults-only one, behind an 18+ gate: 100 statements answered on a slider, six independent axes on a radar and 25 archetypes derived from them, so dominance and surrender can both come out high instead of cancelling each other out.
Popular sign pairs get pages of their own with the full reading: a separate score for each gender arrangement, a same-sex version, ratings across five areas, strengths and advice. They all live in the compatibility horoscopes section.
Every tool calculates in the browser. Answers and birth dates are never uploaded, no account is needed, and there is no limit on how many checks you run.
