Sleep Score

A nightly 0-100 score measuring sleep quality across four pillars: duration, stages, consistency, and interruptions.

Resilience Score

A weekly 0-100 score measuring autonomic nervous system stability through Heart Rate Variability Coefficient of Variation.
The scores have been developed by a team of scientists and ML engineers and interpret physiological data into actionable score metric.

​
Interpreting the Scores

Both scores use a 0-100 scale. A higher score indicates a better outcome.
ScoreScaleHigher score means
Sleep Score0-100Better sleep quality
Resilience Score0-100Better HRV consistency
Neither score is a diagnostic tool. They are intended to surface trends and patterns over time.

Provider Scores vs. OW Native Scores

In addition to the OW native scores described above, users may also see scores fetched directly from their connected device providers - for example, a sleep score from Garmin or a readiness score from Oura. These provider scores are always clearly labelled with their source and are kept separate from the OW computed scores. They do not influence each other. This means you can surface both in your application - the OW scores for a consistent cross-device baseline, and the provider scores for users who want to compare against what their device reports.
