Sleep timing analysis

Correlate bedtime, wake time, and duration with your overnight metrics.

Updated 2026-06-28

Timing analysis looks at when you slept — bedtime, wake time, and total duration — and correlates it with your overnight metrics.

Timing analysis plots bedtime and wake time against ODI, mean HR, and CVHR.
Timing analysis plots bedtime and wake time against ODI, mean HR, and CVHR.

What it shows

  • Scatter plots of bedtime and wake time against ODI-3%, mean heart rate, and CVHR.
  • A plain-language read of each correlation (for example, "moderate negative correlation").

Correlations need a handful of nights before they mean much. The more sessions you sync, the more reliable the timing trends become.

Pair this with event tagging to separate when you slept from what you did that day.
