Lumina Log

Understand last night faster with on-device sleep insight. Lumina Log turns Apple Health data into readiness, sleep balance, stage flow, and weekly recovery patterns.

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.
