In the video on this page, extracted from the keynote that opened Apple’s WWDC21, a new Apple Watch feature that users will be able to use when the new watchOS8 operating system is released, dedicated to the importance of moments of reflection in the hectic life of everyday. The new Mindfulness app includes a feature called “Reflect” which can last just a minute and which shows messages on the display such as: “Remember a moment when you felt a sense of calm and try to transpose it here, now”. Not only. WatchOS 8 helps the user achieve their sleep goals by creating a bedtime routine and tracking data such as hours of sleep, heart rate and blood oxygen level. The new operating system of the Apple Watch offers even more information on general well-being by also monitoring the respiratory rate, or the number of breaths per minute. To do this, Apple Watch uses the built-in accelerometer with which it measures breathing rate during sleep, and this information can be viewed alongside trends in the Health app on the iPhone.
