Discover your natal chart, daily transits and compatibility with Lumi, a private AI. Android & iOS. Join the closed beta — free, no signup yet.

Hey Product Hunt! Solo founder here 👋 Every astrology app I tried felt single-player: you get your chart, you read your horoscope… alone. But astrology is inherently social — "what's your sign?" is how people flirt, bond and tease each other. So I built VibeKin around your people, not just you. Add your inner circle — a name and a birth date is enough, they don't even need the app — and get real compatibility readings. Connected pairs get a daily duo question and a guess game ("what will they answer?") with a Know Score tracking how well you actually know each other. And there's Lumi — a private AI companion that knows your chart and remembers your conversations. Nothing you tell Lumi is visible to anyone else, by design. For the technically curious: charts are computed with Swiss Ephemeris, the same engine professional astrologers use. React Native + Expo, NestJS, pgvector for Lumi's memory. Fully localized in English, Portuguese, Spanish and Russian. Android is live today; the iOS build is in review. I'd love honest feedback — especially: what would make you check compatibility with someone you actually know? AMA 🙂

the way you named the AI Lumi and kept the whole vibe soft and approachable instead of leaning into the usual astrology mysticism is a nice touch

@znurkd3a you clocked the exact call we agonized over. the whole astrology space defaults to crystal-ball mysticism and it makes people feel talked-at. we wanted lumi to feel like a friend who happens to know your chart, not an oracle

"soft and approachable" is literally the note taped above the design work. means a lot that it came through — thank you for saying it 🌙
