Hey Product Hunt! 👋 I'm the creator of Lumi. I built Lumi because I was tired of the "privacy trade-off." I wanted a smart AI companion to help me track my mood and journal my thoughts, but I didn't want to send my deepest secrets to a random server in the cloud. With Apple Intelligence and on-device Foundation Models, I realized we don't have to compromise anymore. Lumi is a tailored wellness companion that lives 100% on your iPhone. It combines: 🧠 Empathetic AI that uses CBT-informed logic to support you 📊 HealthKit Insights that show you how sleep & steps affect your mood 🌿 A Digital Sanctuary that grows plants as you build consistent habits 🔒 Zero Data Collection: I literally cannot see your data I'd love for you to try it out and let me know what you think! I'm especially curious: 1. How important is "local-only" privacy to you for health apps? 2. What's one feature you wish your current mood tracker had? Happy to answer any questions about the on-device AI stack or the design!
