Google has brought a feature from Fitbit to the Pixel Watch. Available globally, Sleep Profiles is aimed at detecting changes in sleep patterns. The new feature is tied to a Fitbit Premium membership though, which costs US$9.99 per month or US$79.99 annually.https://www.notebookcheck.net/Google-Pixel-Watch-receives-new-sleep-features-with-latest-software-update.669988.0.html
As a Pixel watch owner - I regret buying them. And new features behind the paywall don't make me happier either. I'd suggest them to better work on battery life..
