*’watchOS’ is the ‘operating system’ of the ‘apple watch’, developed by ‘apple incorporated’*
.
It is based on iOS, the operating system used by the iPhone and iPod Touch, and has many similar features
It was released on April 24, 2015, along with the Apple Watch, the only device that runs watchOS.
watchOS exposes an API called WatchKit for developer use.
The second version, watchOS 2, included support for native third-party apps and other improvements, and was released on September 21, 2015
The third version, watchOS 3, was released on September 13, 2016 to emphasize better performance and include new watch faces and stock apps.
The fourth version, watchOS 4, was released on September 19, 2017.
The fifth version, watchOS 5, was released on September 17, 2018[11] to add more third-party support and new workouts, along with the “Walkie-Talkie” feature.[12]
The sixth version, watchOS 6, was released on September 19, 2019.[13]
The seventh version, watchOS 7, was released on September 16, 2020 to support handwashing and sleep tracking
.
Interface overview
The home screen – rendered by and also known as “Carousel” – is composed of circular application icons, which can be zoomed in and out with the Digital Crown and dragged and launched by touching the display.
Prior to watchOS 3, Glances provided fast access to a summarized view of the most popular native or third-party applications used on Apple Watch
The Glances view was opened with a swipe up gesture from the watch face screen.
With watchOS 3, Glances was replaced by a redesigned Control Center – much like the one in iOS.
The friends menu, invoked with the side button, now acts as a dedicated dock for apps.
Different actions and options appear depending on if the user taps or deep presses which an Apple Watch detects with its pressure-sensitive (Force Touch) Display
‘force touch’ was completely removed in ‘watchOS 7’
and all actions requiring the feature were moved to specific options in the Settings app or to long-press actions.[18]
Supported health metrics
Since its inception, watchOS has supported an increasing number and variety of health metrics for measurement and/or tracking
.
These include…
heart rate
.
maximal aerobic capacity,
otherwise known as VO2 max
(added in watchOS 4,[19]
enhanced in watchOS 7)
.
electrocardiogram
otherwise known as EKG or ECG
(added in watchOS 5.1.2[23])
.
blood oxygen saturation,
otherwise known as SpO2
(added in watchOS 7[20])
.
menstrual cycle status
(added in watchOS 6[24])
sleep duration (added in watchOS 7)
.
HealthKit
For several years, Apple has been developing its HealthKit product in a bid to change the way people interact with their devices. There is also a conscious attempt to penetrate the lucrative healthcare and wellness industry, which many observers believe to hold a huge growth opportunity for Apple.[27] This was confirmed by Jony Ive, Apple’s former chief designer, in an interview. He said that health was a crucial element in the Apple Watch since the day of its inception and that the developmental trajectory of the hardware and the watchOS were geared towards health-based capabilities.[28] Ive pointed out that one of the primary apps that shipped with the first watchOS allowed users to track and communicate as well as encourage them to move, exercise, and stand. He said:
Many of us have our phones with us all the time, but they aren’t connected to you. Imagine having something this powerful with you at all times, and what opportunities that might present to the user. The opportunity is phenomenal. Particularly when [you] don’t understand just where we are today in terms of technology and capability, but where we are headed.[28]
One of the most recent updates to the watchOS included applications that do not only keep users active but also diagnose illnesses. For example, there is the app called DeepHeart, a deep learning network that can detect atrial fibrillation, hypertension, sleep apnea, and diabetes.[29] It taps the HealthKit platform to collect data, particularly those collected by the Apple Watch’s heart sensor.[30]
