We’re excited to announce that we have improve the WASO parameter in our Data API.

Timeline

• Announcement Date: 2021/07/26
• Release Date: 2022/01/14

What's new?

Wake Time After Sleep Onset (WASO) parameter will be updated to take into account both awake time while lying in bed, and starting from now, phases where the user is out of bed.

So far, our WASO estimation only took into account awake time while in bed.

This update will enable our WASO parameter to match its definition in the sleep litterature, which is all the wake time after sleep onset.

What is the impact in current API integration?

No impact. No change in the integration is required. The WASO value that is rendered may change.
