Lumina Log

Lumina Log is a privacy-first sleep companion for people who already track sleep in Apple Health. If you already track sleep in Apple Health, Lumina Log helps answer the next question: what did last night actually mean? Lumina Log reads your recent sleep, heart rate, HRV, and supported overnight signals from Apple Health, then turns them into: - a clear Today summary - Daily Readiness - Sleep Balance - a nightly Timeline - a lightweight weekly review in Trends Why Lumina Log: - Clearer than Apple Health alone Lumina Log focuses on explanation, not raw charts alone. - On-device by default Your Health data stays on your device. - No account required Connect Apple Health and start reviewing recent nights without account setup. - Useful with partial data If HRV or stage detail is limited, Lumina still uses the most reliable available sleep data and tells you what is missing. - Built for the morning check-in Widget and in-app views are designed to help you understand the night quickly. Important: - Lumina Log is for wellness reference and trend tracking. - It is not a medical or diagnostic app.
