Hi Product Hunt — I’m Ryo, the solo maker of KAYA. I made KAYA for the moments when a relationship matters, but it is hard to know what to do next: a reply that feels too short, a feeling you cannot quite name, or a connection that seems to be changing. I did not want to make an app that tells someone their future is fixed. I wanted to make a calmer place to understand yourself, understand the other person, and decide on one small step that still feels like your own. KAYA uses Four Pillars (BaZi) and Zi Wei Dou Shu as prompts for reflection. You can explore your own traits, add the person on your mind, see your compatibility and the flow of the relationship, then receive a gentle daily letter with a practical next step. It is available in English, Japanese, Korean, Traditional Chinese, and Vietnamese. I’m especially interested in whether the relationship and daily-step parts feel clear before you have learned any astrology. If you try it, I’d love to hear what felt useful, what felt confusing, and what you would want KAYA to help with next. Thank you for having us.
