Hey Product Hunt! I’m a solo developer and built Horizon Diary(formerly Journal&Notes) because I wanted a diary that actually helps me see and understand my emotions — not just store text.The 3D interactive word clouds and mood maps blow my mind every single time. Try writing something sad and watch the cloud turn dark and heavy… then write something joyful. Magic.Everything syncs privately via CloudKit, AI polish is on-device when possible, and export looks gorgeous.Would love your brutal feedback and stories!
