The second version, watchOS 2, included support for native third-party apps and other improvements, and was released on September 21, 2015.[6][7][8] The third version, watchOS 3, was released on September 13, 2016, emphasizing better performance and including 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,[9] adding more third-party support and new workouts, along with the “Walkie-Talkie” feature.[10] The sixth version, watchOS 6, was released on September 19, 2019.[11] The seventh version, watchOS 7, was announced on June 22, 2020 at the WWDC event and is scheduled to be released later this year.[12][13]
Interface overview
The home screen (rendered by and also known as "Carousel")[5] 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. Many of the apps are miniaturized, simplified versions of their iOS counterparts.
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.[14] The Glances view was opened with a swipe up gesture from the watch face screen. With watchOS 3, Glances has been replaced by a redesigned Control Center – much like the one in iOS.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.[15] Force Touch was completely removed in watchOS 7, and all actions have been moved.[16]
HealthKit
For several years now, 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.[17] 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.[18] 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.[18]
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.[19] It taps the HealthKit platform to collect data, particularly those collected by the Apple Watch's heart sensor.[20]
