In the keynote speech at Apple's global developer conference, the company launched the latest version of watchos for the first time, that is, the operating system running on Apple watch. Apple claims that it has improved the ability of the apple watch to detect atrial fibrillation (AFib), an irregular heartbeat that can lead to thrombosis, stroke, heart failure and other heart related complications.
With the advent of watchos 9, supported Apple watch device models can now detect "burden", or the frequency of atrial fibrillation in a person within a certain period of time. This morning, Apple The company has obtained 501 (k) approval from the Federal Food and Drug Administration of the United States; Compared with comprehensive approval, 501 (k) approval does not require the company to provide the effectiveness data of clinical trials.
With watchos 9, the supported Apple watch models can now display the heart area to understand your exercise intensity level, set the distance and time interval, and have tactile and voice feedback to tell you when to switch modes during exercise.
New complex features and watch surfaces (including new astronomical surfaces and new lunar surfaces, supporting the Chinese lunar calendar) and exercise modes are part of the watchos 9 version.
There is also a new "form indicator" for runners (the accelerometer and gyroscope of the apple watch can calculate your running form, stride and ground contact time). It provides a new type of exercise for triathlons, which can automatically switch between cycling, swimming and running.
In addition to these, there is a new sleep tracking function. Now watchos 9 can detect rapid eye movement, core and deep sleep stages. And -- through improved health apps on IOS -- new women's health and drug tracking services. For users with meta quest VR head display, apple watch can now display the statistics of move on fitness mobile phones and watch applications. Meta's fitness tracker is used for quest and listed under fitness games.
In watchos 9, applications can be pinned to the surface for quick access, and there is an improved and streamlined Siri user interface.
It is unclear whether all Apple watch models will be upgraded to watchos 9. Watchos 8 supports the apple watch 3 series, but over time, it is not uncommon for apple to exclude older models due to the hardware limitations of these models. With the public beta of watchos 9 coming out -- probably this week -- fortunately, we will be able to confirm it soon.
