On-Device Sleep Clarity

iPhone
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.
