The Google Pixel 4 marked the debut of Google’s custom Soli radar sensor in 2019. It was used for tracking motion and capturing depth information in real time to power Motion Sense. Due to its limited usefulness in real life, Google killed Soli the following year with the Pixel 5. That technology eventually found its way inside the 2021’s Nest Hub (2nd gen), powering Sleep Sensing on the smart display. Google later confirmed the feature would be free through 2022 and become a part of Fitbit Premium after that. The company has seemingly changed its mind and is now making Sleep Sensing free for another year.
