Hey Product Hunt! 👋 We built Dreamside because we couldn't find an app that correlated HealthKit sleep data with dream entries in a way that actually surfaced useful insights. Why does dream recall vary so wildly from night to night? We wanted to know. Dreamside syncs your Apple Watch sleep data with each dream entry and shows correlation insights across multiple health metrics. The app calculates how Total Sleep, Deep Sleep, REM Sleep, HRV, Heart Rate, Blood Oxygen, and more relate to your dream quality — complete with correlation coefficients and confidence levels. You can see insights like "Good dreams happen after 7.3 hours of sleep vs. 6.3 hours for bad dreams" or "Higher HRV correlates with better dream quality (r = 0.47)." What's included in v1.0: • Automatic Apple Watch sleep correlation via HealthKit • Correlation analysis across 8+ sleep/health metrics • Dream journal with emotions, themes, narrative • AI-generated dream artwork • Multiple interpretation lenses (Jungian, Freudian, Islamic, Buddhist, etc.) What's next: • Voice recording → transcription • Enhanced correlation visualizations and trend graphs • Lucid dreaming tools (reality check reminders, dream sign tracking) Built with SwiftUI, HealthKit, StoreKit 2. Small indie team shipping updates every 2-3 weeks based on your feedback. Happy to answer questions! What features would you want to see in a dream journal?
