## What is Sleep Pattern Lab?

Sleep Pattern Lab helps you explore the relationships between your sleep and your health, activity, and fitness data from Apple Health.
Built for Apple Watch users, Sleep Pattern Lab analyzes your sleep records alongside selected health metrics to surface correlations across Total Sleep, Deep Sleep, and REM Sleep. See how patterns in movement, heart rate, recovery, exercise, daylight, mindfulness, and other Apple Health data may relate to the way you sleep.

Sleep Pattern Lab presents your data clearly, with correlation values, sample counts, and statistical evidence included for each result. It gives you a more transparent way to explore sleep patterns while keeping the interpretation grounded in the numbers.

Features include:
- Sleep correlations for Total Sleep, Deep Sleep, and REM Sleep
- Apple Health and Apple Watch sleep data support
- Comparisons with heart rate, HRV, steps, exercise, calories, daylight, respiratory rate, VO2 Max, blood oxygen, mindfulness, and more
- Adjustable date ranges for reviewing longer-term patterns
- Clear correlation values and statistical evidence
- 100% free to use
- Private, on-device health analysis

Your Health data stays on your device. Sleep Pattern Lab does not sell your data, share it with third parties, or use it for advertising or tracking.
Sleep Pattern Lab is for informational use only. Correlations do not prove cause and effect and are not medical advice.
