Hi Product Hunt — I'm Krishna, and I built Shymea solo. It started with one complaint: every astrology app told me the same thing as everyone else born in my month. Sun-sign content is a horoscope column with a login. So I built it the other way round: compute the whole chart first, interpret second. Positions come from NASA JPL's DE442 ephemeris — and rather than just claim accuracy, I published the comparison, 870 positions checked against Swiss Ephemeris: https://www.shymea.com/research/... What changed while building it was how much I ended up leaving to the maths instead of the model. Horary was the clearest case: questions are judged by William Lilly's 1647 rules in code, not by an LLM. I went and checked how many of his 17 considerations the engine actually implements, and published that too — 14 of 17: https://www.shymea.com/research/... The AI layer reads what the chart says. It never invents a placement. Daily guidance follows your real transits. Compatibility compares two full charts, with both people's consent. Astrocartography covers 390 cities. The web tools are free and need no account — birth chart calculator, 14 calculators, and a 36-chapter course. I'd honestly rather have hard questions about the method than upvotes. Ask me anything about the ephemeris, the house system, or exactly where the model is and isn't involved.
