Google is introducing heart and respiratory rate measurement features with the latest update of its Google Fit app. With the new features, users can measure their vitals without the need of a separate device such as a fitness tracker or a smartwatch. The measurements are done using the phone’s cameras and new software algorithms.
Google doesn’t mention the need to use the camera’s flashlight to measure heart rates in the Google Fit app. In the past, similar apps needed the phone’s LED to measure the user’s heart vitals.
