Apple Watch#Seventh generation (Series 7)

Apple design chief Jony Ive became interested in building a watch shortly after Steve Jobs's death in October 2011.{{Cite magazine |last=Pierce |first=David |date=April 2, 2015 |title=iPhone Killer: The Secret History of the Apple Watch |url=https://www.wired.com/2015/04/the-apple-watch |url-status=live |magazine=Wired |archive-url=https://web.archive.org/web/20220618223947/https://www.wired.com/2015/04/the-apple-watch |archive-date=June 18, 2022 |access-date=June 24, 2017}} That December, The New York Times reported that Apple was exploring various ideas, including a "curved-glass iPod that would wrap around the wrist", which users would interact with through the Siri voice assistant, and which "could relay information back to the iPhone".{{Cite web |last=Bilton |first=Nick |date=December 19, 2011 |title=Disruptions: Wearing Your Computer on Your Sleeve |url=https://archive.nytimes.com/bits.blogs.nytimes.com/2011/12/18/wearing-your-computer-on-your-sleeve/ |access-date=October 26, 2023 |website=The New York Times, Bits Blog |language=en}} In February 2013, the NYT and The Wall Street Journal again confirmed that Apple was working on a smartwatch with a curved display,{{Cite web |last=Toor |first=Amar |date=February 10, 2013 |title=Apple is 'experimenting' with curved glass smartwatch, says NYT and WSJ |url=https://www.theverge.com/2013/2/10/3973364/apple-rumored-to-be-developing-ios-based-smartwatch |url-status=live |archive-url=https://web.archive.org/web/20150715114454/http://www.theverge.com/2013/2/10/3973364/apple-rumored-to-be-developing-ios-based-smartwatch/in/4286985 |archive-date=July 15, 2015 |access-date=July 15, 2015 |website=The Verge}} and Bloomberg News said the team had grown to about 100 designers.{{Cite news |last1=Burrows |first1=Peter |last2=Satariano |first2=Adam |date=February 13, 2013 |title=Apple Said to Have Team Developing Wristwatch Computer |work=Bloomberg News |url=https://www.bloomberg.com/news/articles/2013-02-12/apple-said-to-have-team-developing-wristwatch-computer |url-status=live |access-date=July 15, 2015 |archive-url=https://web.archive.org/web/20150624030452/http://www.bloomberg.com/news/articles/2013-02-12/apple-said-to-have-team-developing-wristwatch-computer |archive-date=June 24, 2015}}

In March 2013, Apple hired ex-Adobe chief technology officer Kevin Lynch, reporting to Bob Mansfield,{{Cite news |last=Satariano |first=Adam |date=March 20, 2013 |title=Apple Hires Adobe Technology Chief Kevin Lynch as Vice President |language=en |work=Bloomberg News |url=https://www.bloomberg.com/news/articles/2013-03-19/apple-hires-adobe-executive-kevin-lynch-as-vice-president |access-date=October 26, 2023}} to lead the watch project, which would become the company's first major new product without input from late co-founder Steve Jobs. Apple started the project without specific use cases in mind, not knowing what problems the watch would solve, but felt that "technology was going to move onto the body", according to Alan Dye, who was in charge of its user interface. According to Kevin Lynch, the team felt people spent too much time on their phone, nagged by notifications, and a watch would provide "that level of engagement [...] in a way that's a little more human, a little more at the moment when you're with somebody".

In July 2013, Financial Times reported that Apple had begun hiring more employees to work on the smartwatch, and that it was targeting a retail release in late 2014.{{Cite web |date=July 14, 2013 |title=Apple on iWatch hiring blitz ahead of possible late 2014 launch, says Financial Times |url=https://www.theverge.com/2013/7/14/4522898/apple-on-iwatch-hiring-blitz-and-could-launch-next-year-says/in/4286985 |url-status=live |archive-url=https://web.archive.org/web/20150715104924/http://www.theverge.com/2013/7/14/4522898/apple-on-iwatch-hiring-blitz-and-could-launch-next-year-says/in/4286985 |archive-date=July 15, 2015 |access-date=July 15, 2015 |website=The Verge}}

The software evolved more quickly than the hardware. To test it, the team created its first prototype, an iPhone strapped to the wrist with Velcro, which showed the Apple watch software in its true size and an onscreen watch crown for input. The crown was later turned into a physical dongle plugged into the headphone jack. Early on, the user interface and bundled apps were inspired by the iPhone, but they were too complex and underwent three rounds of redesigns, to avoid awkwardly long interactions that would annoy users. The team worked on notification vibrations and sounds for more than a year, attempting to make them reflect the nature of different notifications. They also added a way to show a contextual menu by pressing the display more deeply, called Force Touch. In contrast with Apple's usually narrow design options, the team thought a watch would need to appeal to users' diverse tastes in fashion, so they opted to give a choice of bands, models (like the gold-plated Apple Watch Edition) and watch faces.

In April 2014, Apple CEO Tim Cook told The Wall Street Journal that the company was planning to launch new products that year, but revealed no specifics.{{Cite news |last=Wakabayashi |first=Daisuke |date=April 24, 2014 |title=Apple's Cook on New Products: 'Take the Time to Get It Right' |work=The Wall Street Journal |url=https://blogs.wsj.com/digits/2014/04/24/apples-cook-on-new-products-take-the-time-to-get-it-right |url-status=live |access-date=July 15, 2015 |archive-url=https://web.archive.org/web/20150715150709/http://blogs.wsj.com/digits/2014/04/24/apples-cook-on-new-products-take-the-time-to-get-it-right |archive-date=July 15, 2015}}

In June 2014, Reuters reported that production of a smartwatch product was expected to begin in July for an October release.{{Cite web |date=June 19, 2014 |title=Apple's iWatch may launch in October with 2.5-inch screen, says Reuters |url=https://www.theverge.com/2014/6/19/5825178/apple-iwatch-could-launch-in-october/in/4286985 |url-status=live |archive-url=https://web.archive.org/web/20180308231328/https://www.theverge.com/2014/6/19/5825178/apple-iwatch-could-launch-in-october/in/4286985 |archive-date=March 8, 2018 |access-date=August 30, 2017}}{{Subscription required}}

During a September 2014 press event where the iPhone 6 was also presented, the new watch product was introduced by Tim Cook's "one more thing" section. After a video focusing on the design process, Cook reappeared on stage wearing an Apple Watch.{{Cite web |date=September 9, 2014 |title=Apple Watch announced: available for $349 early next year |url=https://www.theverge.com/2014/9/9/6125873/apple-watch-smartwatch-announced |url-status=live |archive-url=https://web.archive.org/web/20140909183047/http://www.theverge.com/2014/9/9/6125873/apple-watch-smartwatch-announced |archive-date=September 9, 2014 |access-date=July 15, 2015 |website=The Verge}}; {{Cite web |date=September 9, 2014 |title=The Apple Watch is poised to dominate the market for digital fitness trackers |url=https://www.theverge.com/2014/9/9/6127839/apple-watch-healthkit-digital-health-fitness |url-status=live |archive-url=https://web.archive.org/web/20220525110122/https://www.theverge.com/2014/9/9/6127839/apple-watch-healthkit-digital-health-fitness |archive-date=May 25, 2022 |access-date=July 15, 2015 |website=The Verge}}

In comparison to other Apple products and competing smartwatches, marketing of the Apple Watch promoted the device as a fashion accessory.{{Cite news |title=Apple Watch is competing as a fashion accessory, and that's a risky move |newspaper=The Washington Post |url=https://www.washingtonpost.com/blogs/innovations/wp/2015/03/05/apple-watch-is-competing-as-a-fashion-accessory-and-thats-a-risky-move |url-status=live |access-date=July 15, 2015 |archive-url=https://web.archive.org/web/20150716123229/http://www.washingtonpost.com/blogs/innovations/wp/2015/03/05/apple-watch-is-competing-as-a-fashion-accessory-and-thats-a-risky-move |archive-date=July 16, 2015}}; {{Cite web |date=February 26, 2015 |title=First Apple Watch ads in U.S. magazines favor fashion lovers over techies |url=http://mashable.com/2015/02/25/apple-watch-vogue |url-status=live |archive-url=https://web.archive.org/web/20150716015123/http://mashable.com/2015/02/25/apple-watch-vogue |archive-date=July 16, 2015 |access-date=July 15, 2015 |website=Mashable}} Apple later focused on its health and fitness-oriented features, in an effort to compete with dedicated activity trackers.

The device was not branded as "iWatch", which would have put it in line with its product lines such as iPod, iPhone, and iPad. In the United States, the "iWatch" trademark is owned by OMG Electronics – who was crowdfunding a device under the same name; it is owned in the European Union by Irish firm Probendi.{{Cite news |title=Non-Apple companies hold iWatch trademark in U.S., U.K., China |url=https://www.cnet.com/news/non-apple-companies-hold-iwatch-trademark-in-u-s-u-k-china |url-status=live |archive-url=https://web.archive.org/web/20150715164450/http://www.cnet.com/news/non-apple-companies-hold-iwatch-trademark-in-u-s-u-k-china |archive-date=July 15, 2015 |access-date=July 15, 2015 |website=CNET}}; {{Cite web |date=April 9, 2015 |title=Why the Apple Watch isn't called the iWatch |url=https://www.cnbc.com/2015/04/09/why-the-apple-watch-isnt-called-the-iwatch.html |url-status=live |archive-url=https://web.archive.org/web/20150715114811/http://www.cnbc.com/2015/04/09/why-the-apple-watch-isnt-called-the-iwatch.html |archive-date=July 15, 2015 |access-date=July 15, 2015 |website=CNBC |publisher=NBCUniversal News Group}} In July 2015, Probendi sued Apple Inc. for trademark infringement, arguing that through keyword advertising on the Google search engine, it caused advertising for the Apple Watch to appear on search results pages when users searched for the trademarked term "iWatch".{{Cite web |date=July 14, 2015 |title=The Apple iWatch doesn't exist, but a legal fight over it does |url=https://arstechnica.com/tech-policy/2015/07/the-apple-iwatch-doesnt-exist-but-a-legal-fight-over-it-does |url-status=live |archive-url=https://web.archive.org/web/20150715112842/http://arstechnica.com/tech-policy/2015/07/the-apple-iwatch-doesnt-exist-but-a-legal-fight-over-it-does |archive-date=July 15, 2015 |access-date=July 15, 2015 |website=Ars Technica}}

Originally at launch, the Apple Watch was marketed as one of three "collections", designating the case material. In order of increasing cost, the collections were:

• Apple Watch Sport (aluminium case)
• Apple Watch (stainless-steel case)
• Apple Watch Edition (originally released as an 18kt gold casing with newer materials in later models)

Starting with Series 1/Series 2, Apple dropped the "Sport" moniker from the branding (apart from the sport bands), and the Apple Watch was available with either an aluminum (lowest cost) or stainless steel case. "Apple Watch Edition" branding still exists, but now refers to watch casings made from ceramic or titanium.{{Cite web |date=September 16, 2016 |title=Watch the Watch! |url=https://www.imore.com/apple-watch-series-2-unboxing |url-status=live |archive-url=https://web.archive.org/web/20210308021754/https://www.imore.com/apple-watch-series-2-unboxing |archive-date=March 8, 2021 |access-date=March 26, 2021 |website=iMore}}

Apple did not explicitly market the first-generation Apple Watch as being waterproof, stating that it can withstand splashes of water (such as rain and hand washing), but does not recommend submersion (IPX7). Apple introduced a higher level of water resistance with the release of the Apple Watch Series 2, and the device was explicitly advertised as being suitable for swimming and surfing. The Series 7 also includes an IP6X certification for dust resistance.{{Cite web |title=Apple Watch Series 7 - Technical Specifications |url=https://support.apple.com/en-us/111909 |access-date=2025-03-11 |website=Apple Support |language=en}}{{Cite web |last=Vivek |date=2021-09-16 |title=What Do IP6X And WR50 Ratings On Apple Watch Series 7 Stand For? |url=https://www.gizbot.com/accessories/features/what-do-ip6x-and-wr50-ratings-on-apple-watch-series-7-stand-for-076807.html |access-date=2025-03-11 |website=Gizbot |language=en}}

Since the introduction of the Apple Watch, it has been available in two sizes (Apple Watch Ultra being the exception), primarily affecting screen resolution and area.

The overall shape and width of the watch has not changed significantly since its release, so customizable bands and accessories are typically compatible with any Apple Watch of the same size class.

It does not have a built-in GPS chip, instead relying on a paired iPhone for location services.

For legal reasons, blood oxygen monitoring is not available on Apple Watch Series 9 and Ultra 2 models sold in the United States after January 18, 2024.{{Cite web |last=Peters |first=Jay |date=January 18, 2024 |title=Apple Watches without banned blood oxygen features are now on sale |url=https://www.theverge.com/2024/1/17/24042395/apple-watch-ultra-2-series-9-ban-blood-oxygen-stores |access-date=February 28, 2024 |website=The Verge |language=en}}

Following a ruling by the International Trade Commission on a lawsuit regarding the blood oxygen monitoring feature, Apple temporarily stopped selling Apple Watch Series 9 and Ultra 2 on December 21, 2023, ahead of an import ban going into effect December 26, 2023. At the time, 9to5Mac reported, "Apple says that the ITC’s ban only impacts sales of the Apple Watch Series 9 and Apple Watch Ultra 2 because those devices offer blood oxygen monitoring capabilities." A US Federal Appeals Court paused the import ban pending a US Customs and Border Protection ruling on whether Apple's changes would be enough to avoid the patent dispute, and Apple resumed sales on December 27, 2023.

As of May 2024, there have been no updates made to the Series 9 / Ultra 2 blood oxygen sensor issues.

Apple markets the Series 9 and Ultra 2 as its first-ever carbon-neutral products (depending on the selected case material and band) due to a combination of cutting the carbon dioxide emissions per watch manufactured and sold (Apple claims a reduction of 78% for the Series 9 and 81% for the Ultra 2{{refn|name=EmissionsNumbers|Series 9 emissions decreased from 36.7kg to 8.1kg, and Ultra 2 emissions from 63.2kg to 12kg{{Cite web |date=September 12, 2023 |title=Apple Watch Ultra 2 — Carbon Neutral Product Environmental Report |url=https://www.apple.com/environment/pdf/products/watch/Carbon_Neutral_Apple_Watch_Ultra_2_Sept2023.pdf |access-date=October 26, 2023 |website=Apple}}}}) and the company's purchases of forestry and nature-based carbon offsets and credits—which some criticized for being misleading due to reliability issues in carbon accounting for forestry carbon offsets.{{Cite news |last=Clifford |first=Catherine |date=October 6, 2023 |title=How Apple made its first 'carbon neutral' product |publisher=CNBC |url=https://www.cnbc.com/2023/10/06/how-apple-made-its-first-carbon-neutral-product-apple-watch.html |access-date=October 6, 2023}}

Most of Apple's claimed emissions reductions were driven by renewable energy requirements imposed on suppliers; other factors include increased use of recycled materials, and a lower reliance on shipping products by plane, which is highly carbon-intensive. Apple says the watches' manufacturing relies on "100% clean electricity", though this partly relies on Apple investing in clean-energy projects to offset suppliers' use of electricity produced from fossil fuels. NewClimate Institute, a non-profit, said Apple's "100 per cent clean energy" claim was "highly contentious, since Apple’s major suppliers continue to have very low renewable electricity shares".{{Cite news |last=Bryan |first=Kenza |date=October 24, 2023 |title=Apple's 'carbon neutral' claims come under scrutiny |url=https://www.ft.com/content/90392004-97e0-4444-a5cd-82220fe52510 |url-access=subscription |access-date=October 26, 2023 |work=Financial Times}}

On September 20, 2023, the European Union announced that it would ban most uses of the term "carbon neutral" in advertising by 2026, including claims that are based on carbon offsets, to address greenwashing and misleading advertising. This decision was praised by Monique Goyens, director-general of EU consumer group BEUC, who also called Apple's claims "bogus" and scientifically inaccurate. Gilles Dufrasne, policy officer at non-profit Carbon Market Watch, said it was "misleading to consumers" for Apple to give "the impression that buying the Watch has no impact on the climate at all", based on what he described as "accounting tricks". Other environmental groups criticized Apple's emphasis on carbon emissions without accounting for e-waste, due to the difficulty of repairing these products.{{Cite news |last=Hancock |first=Alice |date=September 20, 2023 |title=EU to ban 'climate neutral' claims by 2026 |url=https://www.ft.com/content/53f84f03-1f1c-4240-977f-9de0e4893377 |url-access=subscription |access-date=October 26, 2023 |work=Financial Times}}{{Cite web |last=Kurmayer |first=Nikolaus J. |date=September 20, 2023 |title=EU reaches deal banning 'climate-neutral' product claims |url=https://www.euractiv.com/section/energy-environment/news/eu-reaches-deal-banning-climate-neutral-product-claims/ |website=Euractiv}} Berkeley Carbon Trading Project director Barbara Haya praised the products' ~80% emissions reduction, but also criticized Apple's use of the term "carbon neutral" in advertising.

watchOS is a distinct operating system designed specifically for Apple Watch. While based on iOS, which is used in iPhones, it offers a tailored experience for the smaller screen and wrist-worn form factor.

Features:

• Timekeeping: Telling time is a core function with various watch faces to choose from.
• Notifications: View and respond to notifications from an iPhone directly on a watch.
• Health and Fitness: Extensive health and fitness tracking features like heart rate monitoring, workout programs, and activity rings to stay motivated.
• Apps: Download and use various apps specifically designed for Apple Watch, covering fitness, communication, news, and more.
• Integration with iPhone: Works seamlessly with an iPhone for functions like making calls, sending texts, unlocking an iPhone, and using Apple Pay.
• Updates: Apple frequently releases updates to watchOS, bringing new features, bug fixes, and security improvements. One can update a watch through the Watch app on an iPhone or directly on the Apple Watch itself (if it has watchOS 6 or later).

Apple Watch runs watchOS, whose interface is around a home screen with circular app icons, which can be changed to a list view in the devices settings. The OS can be navigated using the touchscreen or the crown on the side of the watch. During its debut, the first generation Apple Watch needed to be paired with an iPhone 5 or later running iOS 8.2 or later; this version of iOS introduced the Apple Watch app, which is used to pair the watch with an iPhone, customize settings and loaded apps, and highlight compatible apps from the App Store.{{Cite web |date=May 3, 2015 |title=Review: The absolutely optional Apple Watch and Watch OS 1.0 |url=https://arstechnica.com/apple/2015/05/review-the-absolutely-optional-apple-watch-and-watch-os-1-0 |url-status=live |archive-url=https://web.archive.org/web/20170705153302/https://arstechnica.com/apple/2015/05/review-the-absolutely-optional-apple-watch-and-watch-os-1-0 |archive-date=July 5, 2017 |access-date=July 15, 2015 |website=Ars Technica}}

The Apple Watch is capable of receiving notifications, messages, and phone calls via a paired iPhone. "Glances" allowed users to swipe between pages containing widget-like displays of information; however, this feature was replaced by a new Control Center. watchOS also supports Handoff to send content from Apple Watch to an iOS or macOS device, and act as a viewfinder for an iPhone camera,{{Cite web |date=September 9, 2014 |title=The Verge: The 15 most important announcements from the Apple Watch, iPhone 6 event |url=https://www.theverge.com/2014/9/9/6107091/apple-watch-iphone-6-most-important-things |url-status=live |archive-url=https://web.archive.org/web/20140909232238/http://www.theverge.com/2014/9/9/6107091/apple-watch-iphone-6-most-important-things |archive-date=September 9, 2014 |access-date=September 10, 2014 |website=The Verge |publisher=Vox Media}} Siri is also available for voice commands, and is capable of responding with voice prompts on the Series 3 watches. Apple Watch also supports Apple Pay, and enables its use with older iPhone models that do not contain near-field communication (NFC) support.

Apple Watch's default apps are designed to interact with their iOS counterparts, such as Mail, Phone, Calendar, Messages, Maps, Music, Photos, Reminders, Remote (which can control iTunes and Apple TV), Stocks, and Wallet. Using the Activity and Workout apps, a user can track their physical activity and send data back to the iPhone for use in its Health app and other HealthKit-enabled software. With watchOS 3, Reminders, Home, Find My Friends, Heart Rate, and Breathe were added to the stock apps.

At WWDC 2015, Tim Cook announced watchOS 2.0; described by CNET as a "significant revamp", it included a new software development kit that allows more direct access to the device's hardware, new watch faces, the ability to reply to an e-mail, and other features.{{Cite web |title=Get ready for Apple Watch 2.0 |url=https://www.cnet.com/news/get-ready-for-apple-watch-2-0 |url-status=live |archive-url=https://web.archive.org/web/20150610015933/http://www.cnet.com/news/get-ready-for-apple-watch-2-0 |archive-date=June 10, 2015 |access-date=June 10, 2015 |website=CNET}} WatchOS 2.0 was released in September 2015.{{Cite web |last=Cunningham |first=Andrew |date=September 21, 2015 |title=After delay, Apple releases watchOS 2.0 to the public |url=https://arstechnica.com/apple/2015/09/after-delay-apple-releases-watchos-2-0-to-the-public |url-status=live |archive-url=https://web.archive.org/web/20150922001233/http://arstechnica.com/apple/2015/09/after-delay-apple-releases-watchos-2-0-to-the-public |archive-date=September 22, 2015 |access-date=September 21, 2015 |website=Ars Technica |publisher=Condé Nast}} Following the software update, some users experienced issues with lag.{{Cite web |date=October 24, 2015 |title=Why I'm cheating on my Apple Watch |url=http://www.cultofmac.com/393831/why-im-cheating-on-my-apple-watch |url-status=live |archive-url=https://web.archive.org/web/20160313132823/http://www.cultofmac.com/393831/why-im-cheating-on-my-apple-watch |archive-date=March 13, 2016 |access-date=March 13, 2016 |website=Cult of Mac}}

watchOS 3.0 was announced at WWDC 2016, with a priority on performance. Users are able to keep apps running in memory as well as receive background updates and refreshed information. Other updates include a new Dock invoked with the side button to replace the performance-laden Glances, an updated Control Center, and new reply options on Messages. Several new watch faces have also been added, including Minnie Mouse, along with the ability to switch watch faces from the lock screen simply by swiping. A new feature called SOS allows users to hold the dock button to make a call to the local emergency line and pull up the user's Medical ID. Another feature is Activity Sharing, which allows sharing of workouts with friends and even sending their heartbeats to one another. A new app called Breathe guides users through breathing exercises throughout the day, with visuals and haptic feedback. It was made available to the public in September 2016.

watchOS 3.1 was released to the public in October 2016, and watchOS 3.2 was released in March 2017.{{Cite web |date=October 24, 2016 |title=Apple Releases watchOS 3.1 to the public with bug fixes, update through iPhone Watch app |url=https://9to5mac.com/2016/10/24/apple-releases-watchos-3-1-to-the-public-with-bug-fixes-update-through-iphone-watch-app |url-status=live |archive-url=https://web.archive.org/web/20170412214615/https://9to5mac.com/2016/10/24/apple-releases-watchos-3-1-to-the-public-with-bug-fixes-update-through-iphone-watch-app |archive-date=April 12, 2017 |access-date=May 27, 2017 |website=9to5Mac |last1=Mayo |first1=Benjamin }} Both updates added minor improvements and bug fixes.

watchOS 4.3 was released in March 2018. It introduced support for Nightstand mode in portrait orientation. It brought back the ability for music playing on the iPhone to be controlled using the Music app on the Apple Watch and also enabled control of playback and volume on Apple's HomePod. Other new features included a new charging animation and a new app loading animation. Activity data was added to the Siri watch face, and the battery complication more accurately reports battery life.

watchOS 5.0 was first shown to the public at the San Jose WWDC developer conference held by Apple. It introduced an instant watch-to-watch walkie-talkie mode, all-new Podcasts app, raise-wrist-to-speak Siri, customizable Control Center, and the ability to access the notification center and control center from apps. Other features included support for WebKit to view web pages, six new watch faces, and new workout running features.{{Cite news |date=September 17, 2018 |title=watchOS 5 for Apple Watch now available with Podcasts and Walkie-Talkie apps, much more |work=9to5Mac |url=https://9to5mac.com/2018/09/17/watchos-5-features |url-status=live |access-date=November 18, 2018 |archive-url=https://web.archive.org/web/20181118122743/https://9to5mac.com/2018/09/17/watchos-5-features |archive-date=November 18, 2018}} It was released to the public in September 2018.{{Cite web |title=Apple Watch Series 4 starts at $399, packs larger displays and EKG sensor – CNET |url=https://www.cnet.com/news/apple-watch-4-rumors-launch-features-leaks-specs-price-release-date-reports-bigger-display |url-status=live |archive-url=https://web.archive.org/web/20180828140416/https://www.cnet.com/news/apple-watch-4-rumors-launch-features-leaks-specs-price-release-date-reports-bigger-display |archive-date=August 28, 2018 |access-date=August 28, 2018}} On the newest release of watchOS beta the sleep feature was shown on screen, this would eliminate the need to use third-party apps.

watchOS 6.0 was released to the public in September 2019. It introduced more native iOS apps such as voice memos, calculator, and a native watchOS app store. watchOS 6.0 also introduced new features such as the noise app that allows one to measure ambient sound in decibels, menstrual tracking, and new watch faces. Other features include Siri being able to tell users what music they are listening to, activity trends, and a new UI framework for developers.

watchOS 7.0 was announced on June 22, 2020, at the WWDC, and released on September 16, 2020; new functions include sleep tracking, additional watch faces, handwashing detection and new workouts such as dancing.

watchOS 8.0 was announced on June 7, 2021, at the WWDC, and released on September 20, 2021. It replaces the Breathe app with a new Mindfulness app, and adds a Focus mode as well as a Portrait Watch Face, updates to the Messages and Home apps, Contacts and Find My apps, and a redesigned Photos app.

watchOS 9.0 was released to public on September 13, 2022. It enhances the Workout display with new views of metrics like Activity rings, Heart Rate Zones, Power, and Elevation. It also supports better sleep tracking and additional watch faces.

watchOS 10.0 was announced on June 5, 2023, at WWDC, and released on September 18, 2023. It includes a major redesign of all stock watchOS apps, more detailed metrics available for cycling workouts, and new "Smart Stacks", stacks of widgets available from the clock.

In watchOS 1, third-party WatchKit applications run in the background on the iPhone as an application extension while a set of native user interface resources are installed on Apple Watch.{{Cite web |last=Cunningham |first=Andrew |date=November 18, 2014 |title=Apple releases WatchKit developer tools alongside first iOS 8.2 beta |url=https://arstechnica.com/apple/2014/11/apple-releases-watchkit-developer-tools-alongside-first-ios-8-2-beta |url-status=live |archive-url=https://web.archive.org/web/20150518081020/http://arstechnica.com/apple/2014/11/apple-releases-watchkit-developer-tools-alongside-first-ios-8-2-beta |archive-date=May 18, 2015 |access-date=May 15, 2015 |website=Ars Technica |publisher=Condé Nast}} Thus, watchOS apps must be bundled within their respective iOS app, and are synced to the watch either manually, or automatically upon installation of the phone app.

With the release of watchOS 2, Apple made it mandatory for new watch apps to be developed with the watchOS 2 SDK from June 1, 2016, onwards; no third-party languages or SDKs can be used to develop apps.{{Cite web |date=April 22, 2016 |title=Apple requires all new watchOS apps be native by June 1 |url=http://appleinsider.com/articles/16/04/22/apple-requires-all-new-watchos-apps-be-native-by-june-1 |url-status=live |archive-url=https://web.archive.org/web/20170429004239/http://appleinsider.com/articles/16/04/22/apple-requires-all-new-watchos-apps-be-native-by-june-1 |archive-date=April 29, 2017 |access-date=May 15, 2017 |website=AppleInsider}} This allowed for developers to create native apps that are run on the watch itself, thus improving the responsiveness of third-party apps.

In watchOS 5 and earlier, all watchOS apps are dependent apps – the watchOS app relies on an iOS companion app in order to function properly.{{Cite web |title=Creating Independent watchOS Apps – Apple Developer Documentation |url=https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps#overview |url-status=live |archive-url=https://web.archive.org/web/20200917012336/https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps#overview |archive-date=September 17, 2020 |access-date=September 20, 2020 |website=Apple Developer}} In watchOS 6 or later, developers are able to create completely independent watchOS apps, and no longer require an app to be installed on the paired iPhone.

In October 2023, the United States International Trade Commission (ITC) ruled that Apple Watch products infringed upon patents for light-based pulse oximetry that are owned by medical technology company Masimo. The company alleged that Apple had approached Masimo with offers to acquire or otherwise partner with the company, and went on to poach engineers from Masimo to develop the infringing technology after it declined the offers. This ruling would allow the ITC to impose an import ban, provided it is not overruled by presidential veto power within a 60-day review period ending December 25.
