iOS 26 and iPadOS 26 will include a preinstalled Preview app from Apple, according to Bloomberg's Mark Gurman.

preview
In a lengthy report outlining his WWDC 2025 expectations today, Gurman said that the Preview app will provide iPhone and iPad users with an all-in-one, built-in solution for managing, editing, and annotating PDF documents.

The app will look similar to Apple's longstanding Preview app on the Mac, he said:

The software looks similar to the Mac version, and its launch screen is in the same style as apps like Pages and Keynote. It includes a big logo on the top portion of the screen advertising the Preview name and a gallery of document options below it.

Gurman did not say if the Preview app on the iPhone and iPad will also offer basic image editing abilities, like it does on the Mac.

iOS 26 and iPadOS 26 will be announced during Apple's WWDC 2025 keynote, which begins on Monday, June 9 at 10 a.m. Pacific Time.

While the so-called "iPhone 17 Air" is not expected to launch until September, there are already plenty of rumors about the ultra-thin device.

iPhone 17 Air Size Feature
Overall, the iPhone 17 Air sounds like a mixed bag. While the device is expected to have an impressively thin and light design, rumors indicate it will have some compromises compared to iPhone 17 Pro models, including worse battery life, only a single rear camera, only a single speaker, and an A19 chip instead of an A19 Pro chip.

Below, we recap 17 key rumors for the iPhone 17 Air as of June 2025:

Apple's upcoming HomePod Software 26 update will support the original first-generation HomePod along with all succeeding HomePod models, according to a private account on X with a proven track record for upcoming software updates.

HomePod White on Console
Apple released the original HomePod eight years ago, so it's good to see that Apple's latest software will support it. As for what the new software will bring to the table in terms of new features, it's not yet clear, but hopefully improvements to the Siri experience are forthcoming.

Rather than naming the next-generation version HomePod Software 19, Apple is likely to call it HomePod Software 26. All of the major software updates coming this year will be numbered "26," reflecting the September 2025 to September 2026 release cycle, so it'd be weird for the HomePod Software not to receive the same treatment.

The HomePod family is expected to grow in size this year or next, with the arrival of Apple's long-rumored smart home hub. We're hoping that Apple provides an early preview of the home hub at WWDC, based on recent trademarking activity.

Apple's WWDC 2025 keynote will begin on Monday, June 9 at 10:00 a.m. Pacific Time. Apple will live stream the event on its website, on YouTube, and in the TV app. If you're not able to watch live, we'll have a live blog and coverage of the announcements here at MacRumors, plus we'll be live tweeting the event on the MacRumorsLive account.

Apple's upcoming tvOS 26 software update will support all Apple TV models that are compatible with tvOS 18, according to a private account on X with a proven track record for upcoming software updates.

tvOS 26 Feature
If this rumor is accurate, and we have high confidence that it is, then tvOS 26 will be compatible with the Apple TV HD – released in 2015(!) – and beyond:

  • Apple TV HD (2015)
  • Apple TV 4K (1st generation, 2017)
  • Apple TV 4K (2nd generation, 2021)
  • Apple TV 4K (3rd generation, 2022)

Rather than naming the next-generation version tvOS 19, Apple is going to call it tvOS 26, our source confirmed. All of the software updates coming this year will be numbered "26," reflecting the September 2025 to September 2026 release cycle.

The visionOS-inspired design coming to iOS, iPadOS, and macOS will also extend to tvOS. While tvOS typically receives less attention and specific details are scarce, we can infer some changes based on iOS rumors.

iOS 26 is expected to feature a visionOS-like interface with translucent elements, floating menus and windows, and softer, rounded visuals. The design uses light and shadow to create a glass-like effect, as seen in Apple's WWDC promotional imagery, so expect these to appear.

We're also expecting new screensavers, a new cross-platform Games app, Wi-Fi syncing, and potential new AI-powered features. For everything we know, be sure to check out our WWDC roundup for tvOS 26.

Apple's upcoming watchOS 26 software update will support all Apple Watch models that are compatible with watchOS 11, according to a private account on X with a proven track record for upcoming software updates.

watchOS 26 Mock Feature
If this rumor is accurate, and we believe it is, watchOS 26 will be compatible with the Apple Watch Series 6 and beyond:

  • Apple Watch SE (2nd generation)
  • Apple Watch Series 6
  • Apple Watch Series 7
  • Apple Watch Series 8
  • Apple Watch Series 9
  • Apple Watch Series 10
  • Apple Watch Ultra
  • Apple Watch Ultra 2

Rather than naming the next-generation version watchOS 12, Apple is going to call it watchOS 26, our source confirmed. All of the software updates coming this year will be numbered "26," reflecting the September 2025 to September 2026 release cycle.

The overhauled design that Apple is introducing for iOS 26 will also extend to the Apple Watch, though the changes to watchOS may not be as dramatic as the iOS 26 refresh. Apple will likely add new watch faces that are designed with the new style.

Apple's upcoming watchOS 26 update could also introduce support for third-party shortcuts in Control Center. For more details on what to expect for Apple Watch at WWDC next week, check out our roundup.

The Nintendo Switch 2 includes a new built-in social feature called GameChat that allows up to 12 users to engage in video chats simultaneously, even if they're playing in different games. To facilitate this, Nintendo offers an official Switch 2 Camera that connects via USB-C, but it turns out that an iPhone does the job just as well, if not better.


Niles Mitchell has thoughtfully shared a demo of the Switch-iPhone configuration that explains how to set it up. You'll need a HDMI to USB-C cable and a HDMI converter cable to connect them, which should cost around $30 in total.

If you aren't lucky enough to own a Switch 2, you can always use your iPhone as a webcam for a Mac. Click the link to learn how it works.

tvOS is probably the Apple operating system that gets the fewest updates each year, and that's not going to change in 2025. But thanks to the design overhaul that Apple is introducing across all of its software platforms, tvOS is set to get some interesting new features.

tvOS 26 Feature

Naming

As we've noted several times this week, Apple is changing the naming for its operating system updates. After tvOS 18, we're getting tvOS 26 instead of tvOS 19. The "26" represents the September 2025 to September 2026 release season for tvOS, with Apple planning to use the same numbering across iOS, iPadOS, macOS, watchOS, and visionOS too.

Updated Design

The visionOS-style design update that's coming to iOS, iPadOS, and macOS will also extend to tvOS. tvOS tends to get little attention comparatively so we don't have specific details on what's changing, but we can extrapolate a bit from the iOS rumors.

iOS 26 will adopt an interface that riffs on visionOS, with a focus on translucency, floating menus and windows, and more rounded design elements. It's been described as using light and shadow to give off a glass-like effect, which we can see in the imagery that Apple is using to promote WWDC.

tvOS 26 could adopt some of the same translucency for menus, app icons, buttons, and other parts of the interface, plus it could get the same floating look and more dramatically rounded edges for buttons and windows that are typical of visionOS.

Apple wants the experience of using its various platforms to feel more cohesive, which is why everything is getting some of the same design changes.

Screensavers

It's typical for Apple to introduce new screensavers with tvOS updates, so we can perhaps expect to see new aerial screensaver options, as well as screensavers that match the updated aesthetic. Last year, Apple came out with Snoopy screensavers, so we could get more of those too, or another partnership.

Games App

Apple plans to debut a new cross-platform Games app that will serve as a one-stop spot for discovering and launching games. On the Apple TV, it will feature a range of games that can run on the device, including third-party games and Apple Arcade games.

The Games app will essentially feature the entire games section of the tvOS App Store. It's also expected to have features like achievements, leaderboards, and recommendations from Apple editors. There might also be new tools for communicating with other players.

Wi-Fi Syncing

If you're in the unusual situation of needing to connect your ‌Apple TV‌ to a captive network at a college or similar location, you'll be glad to hear about a new captive Wi-Fi syncing option that's coming to Apple's platforms.

With this feature, you'll only need to log into a captive network on one of your Apple devices, and the login information will sync to everything else signed into your Apple Account.

Recommendations

There's no rumor about tvOS adopting Apple Intelligence, but Apple is expanding AI across its platforms. tvOS could benefit from AI features that better learn from user preferences to make more tailored content recommendations on what to watch next.

If and when Apple introduces major ‌Apple Intelligence‌ updates to Siri, we could see some of those features available on the ‌Apple TV‌.

WWDC 2025 Keynote

Apple's WWDC 2025 keynote will begin on Monday, June 9 at 10:00 a.m. Pacific Time. Apple will live stream the event on its website, on YouTube, and in the TV app.

Apple's upcoming watchOS 26 update could introduce support for third-party shortcuts in Control Center, according to a report from 9to5Mac. This would allow settings from third-party apps to be accessed right alongside Apple's own Control Center options.

watchOS 26 Mock Feature
Right now, the Control Center on Apple Watch (accessed by pressing the Side button) is limited to Apple's built-in shortcuts for doing things like toggling on Wi-Fi, turning on Airplane mode, activating Do Not Disturb, and pinging the iPhone, but ‌watchOS 26‌ could bring some of the same customizations that Apple added to the ‌iPhone‌ in iOS 18.

‌iOS 18‌ introduced a customizable Control Center that supports third-party shortcuts on the ‌iPhone‌, so it makes sense that the feature might also expand to the Apple Watch. Shortcuts could be useful for activating specialized workouts in third-party apps, launching streaming music apps, logging food and water intake, and more.

The Apple Watch Control Center could get new options for customizing the layout through the Apple Watch app, with Apple allowing users to add new shortcuts and remove those that aren't necessary.

‌watchOS 26‌ is set to debut at the Worldwide Developers Conference, which begins with a keynote event on Monday, June 9.

Google today announced that its Chrome browser has received the "highest ever score" on the Speedometer 3 benchmarking test. Speedometer 3 is designed to measure browser performance, and it was created collaboratively by Google, Apple, Intel, Microsoft, and Mozilla.

Chrome Feature 22
The test is designed to measure web responsiveness through several workloads like HTML parsing, JavaScript and JSON processing, pixel rendering, CSS application, and more.

Optimizations that Google has implemented over the last year have brought a 10 percent improvement in performance since August 2024, which Google says leads to better browser experiences for end users.

The team heavily optimized memory layouts of many internal data structures across DOM, CSS, layout, and painting components. Blink now avoids a lot of useless churn on system memory by keeping state where it belongs with respect to access patterns, maximizing utilization of CPU caches. Where internal memory was already relying on garbage collection in Oilpan, e.g. DOM, the usage was expanded by converting types from using malloc to Oilpan. This generally speeds up the affected areas as it packs memory nicely in Oilpan's backend.

On an M4 MacBook Pro with macOS 15, Chrome 139 achieved a score of 52.35 on the benchmarking test. More detail on the optimizations that were added can be found in Google's blog post.

Apple has not recently shared its maximum Speedometer 3 test results for Safari so there isn't a direct comparison available, and it is worth noting that Google appears to have used Speedometer 3, and not the newer Speedometer 3.1 test.

We're just a handful of days away from the 2025 Worldwide Developers Conference, where Apple plans to introduce new versions of iOS, iPadOS, macOS, tvOS, watchOS, and visionOS. visionOS isn't Apple's most popular platform, but it's getting new features that will make the Vision Pro experience better.

visionOS 26 Feature
The next version of visionOS has actually been described as "feature-packed," but a lot of what's coming will remain a surprise because rumors typically focus on iOS. If you're expecting visionOS 3 to follow visionOS 2, you might be surprised when we get visionOS 26 instead. Apple is changing the way that it names operating system updates, using "26" for everything coming out in 2025. 26 represents the September 2025 to September 2026 visionOS season.

Updated Design

The design that Apple used for visionOS is inspiring a new look for iOS and macOS, but Apple also plans to make some tweaks to the way that visionOS looks. The changes are likely to be small in scale, and we don't have a lot of detail, but at least some visual updates are coming.

Eye-Scrolling

Apple is going to add a new eye-scrolling option to the Vision Pro, which will use the built-in eye tracking features. The Vision Pro already supports navigating through the OS by looking at something on the display and then using a hand gesture to "tap" it, so eye-based scrolling is a natural extension of that functionality.

Apple will add eye scrolling to the built-in Apple apps, and it will provide an API that will let developers integrate the capability into third-party apps as well.

Apple Intelligence

Apple is planning to add new Apple Intelligence features to iOS, and it's possible anything that's added will also expand to visionOS. There's an AI battery management feature rumored for iOS 26, for example, and it would make a lot of sense to have a similar function on the headset because it's so reliant on battery.

At some point, Apple will introduce the ‌Apple Intelligence‌ personalized Siri features that were shown off at WWDC 2024, and those capabilities will almost certainly expand to the Vision Pro. Apple is working on deeper ‌Siri‌ integration for apps, personal context that would let ‌Siri‌ access emails, files, and more, and onscreen awareness so ‌Siri‌ knows what you're looking at.

Games App

Apple plans to release a new cross-platform Games app, and with the company aiming to push gaming on the Vision Pro, the Games app will likely be available on the headset. The Games app will include all the content from the games section of the App Store, along with Apple Arcade content and Game Center features like achievements and leaderboards.

Accessibility

In May, Apple announced upcoming Accessibility features that will be added to visionOS 26. visionOS is going to get new vision accessibility options for users who are blind or have low vision. Zoom will let users magnify anything that's in view using the main Vision Pro camera, while Live Recognition in VoiceOver will use on-device machine learning to describe surroundings, find objects, and read documents.

Apple is developing a new API that will allow approved apps to use the main camera for providing live, person-to-person assistance for visual interpretation, a feature that will be useful for apps like Be My Eyes.

For users with severe mobility disabilities, visionOS is gaining a new protocol that will support Switch Control for Brain Computer Interfaces, a technology that lets users control their devices with brain signals.

WWDC 2025 June 9 Keynote

Apple's WWDC 2025 keynote will begin on Monday, June 9 at 10:00 a.m. Pacific Time. Apple will live stream the event on its website, on YouTube, and in the TV app.

Apple's long-rumored "homeOS" operating system might finally be on the horizon, based on recent trademark activity reviewed by MacRumors.

homeOS2
An apparent shell company known as Home Operations Suite LLC has submitted trademark applications for "HOMEOS" in a handful of countries in recent months. A priority filing was made in Liechtenstein in October 2024, and additional filings were made in the United States, Argentina, Peru, and a few other countries in April this year.

The trademark is now registered in Liechtenstein, but the applications are still pending elsewhere.

The trademark filing in the U.S. was first spotted by Parker Ortolani and reported by 9to5Mac.

There is no definitive proof that Apple owns the shell company, but it has a history of creating limited-liability companies with generic names in order to discreetly move to protect its intellectual property related to unannounced products.

For example, in May 2023, MacRumors uncovered a "VisionOS" trademark application filed by another secretive LLC shell company. A month later, at WWDC, Apple announced its Vision Pro headset and its visionOS operating system.

"homeOS" has been referenced in various other places in the past, including in Apple job listings, and in tvOS 17.4 code discovered by MacRumors. It could end up being the name of the software platform that powers Apple's long-rumored smart home hub, which has been described as a HomePod with a screen. The device will reportedly have a square iPad-like screen that can be attached to a speaker base or mounted on a wall.

The hub would allow users to control smart home accessories, make FaceTime video calls, use Apple's intercom feature between rooms in a house, and more. It might even double as a home security system with an Apple-designed smart home camera.

In March, Apple supply chain analyst Ming-Chi Kuo said that the HomePod with a screen would enter mass production in the third quarter of 2025, but it is unclear if it will ship to customers this year or next year. Apple delayed the personalized Siri features that are expected to be at the core of the device, so perhaps next year is a safer bet at this point. However, Apple could still provide an early preview of the home hub at any point now, and its WWDC 2025 keynote just so happens to be coming up next week. Stay tuned!

Apple Pay on the iPhone can be used for making PlayStation purchases on the PS4 and PS5, Sony confirmed today. The feature has been rolling out to PlayStation 5 users over the course of the last few weeks, but it is now available more widely and also on the PS4.

apple play playstation
The option to use ‌Apple Pay‌ is notable because it is a feature that works when you're making PlayStation Store purchases directly on a PS4 or PS5 from the television interface. To do so, add a game to your cart and then go to checkout.

In the checkout interface, select ‌Apple Pay‌. From there, the PlayStation will display an Apple payment code (essentially an Apple-designed QR code) that can be scanned with an ‌iPhone‌ or an iPad, with payment confirmed through biometric authentication.

Apple implemented support for this type of payment with iOS 18 last year. It also works for purchases on third-party browsers like Chrome and Firefox.

‌Apple Pay‌ is available alongside PayPal and traditional debit and credit card payment options on Sony's consoles, and using ‌Apple Pay‌ may be more secure and convenient than entering in a credit or debit card number.

iOS 18 adoption has outpaced iOS 17 adoption during the same timeframe last year, according to new ‌iOS 18‌ adoption statistics that Apple shared today.

iOS 18 on iPhone Arrow Down
‌iOS 18‌ is now installed on 88 percent of iPhones introduced in the last four years (iPhone 13 and newer), and 82 percent of all active iPhones. ‌iOS 18‌ adoption has grown notably since earlier this year. In January, 76 percent of iPhones introduced in the last four years had ‌iOS 18‌ installed, while 68 percent of all iPhones were running the update.

Compared to last year, ‌iOS 18‌ is more popular than iOS 17. In June 2024, 86 percent of all iPhones from the last four years had iOS 17, while 77 percent of all iPhones were running it.

As for the iPad, iPadOS 18 is currently installed on 81 percent of iPads introduced in the last four years, while 71 percent of total devices run ‌iPadOS 18‌. ‌iPadOS 18‌ has also been adopted more rapidly than iPadOS 17 in June 2024. During that time period, iPadOS 17 was installed on 77 percent of all iPads released in the last four years and 68 percent of all iPads.

Apple Intelligence features in ‌iOS 18‌ like Writing Tools, Genmoji, Image Playground, and notification summaries may have spurred the uptick in adoption between iOS 17 and ‌iOS 18‌.

Apple views software updates as an integral part of the ‌iPhone‌ usage experience. Apple is able to deliver new functionality to older iPhones on a regular basis, plus the frequent updates that Apple rolls out address bugs and ensure the best protection from security vulnerabilities.

Apple says that providing ‌iPhone‌ users with new features over multiple years is something that is unique to the ‌iPhone‌ because of the deep integration between hardware and software. Apple views software updates as a way to provide value to customers over a long period of time, enabling them to hold onto their devices for years while still getting new experiences.

The newest version of iOS is set to debut next week at the Worldwide Developers Conference. We'll get a look at ‌iOS 18‌'s successor, which rumors say will bring some major design changes and exciting new features.

Snap today announced the launch of a Snapchat app that's designed for the Apple Watch. Snapchat users can now view and respond to conversations right from their wrists.

snapchat apple watch
The Snapchat app supports replies with the built-in Apple Watch keyboard, Scribble, and Dictation, plus it supports sending emoji, like any other Apple Watch messaging app.

Snap says that it is committed to making Snapchat available across all devices that Snapchat users own, including wearable devices like the Apple Watch.

It is rare for a major company to roll out an Apple Watch app these days, as it has not proven to be a popular platform. Slack, Facebook Messenger, Uber, Lyft, and more were all once available on the Apple Watch but have been discontinued after companies found that the development resources were not worth it.

Eight years ago today, Apple introduced the HomePod, a smart speaker that it said would provide "amazing sound quality and intelligence" in the home.

HomePod White on Console
"Apple reinvented portable music with iPod and now HomePod will reinvent how we enjoy music wirelessly throughout our homes," said Apple's former marketing chief Phil Schiller, in a June 2017 press release announcing the HomePod.

While the original HomePod's sound quality did impress reviewers when it launched, Apple largely failed to deliver on the intelligence front. Siri is widely considered to be inferior to other popular voice assistants, like Amazon's Alexa, and the rise of chatbots like OpenAI's ChatGPT and Google's Gemini have set Siri even further back.

Apple went on to launch the HomePod mini in November 2020, before making the surprise decision to discontinue the full-size HomePod in March 2021. At the time, Apple said that it discontinued the full-size HomePod in order to focus its efforts on the HomePod mini, but declining sales were also likely a factor. Somewhat unexpectedly, the HomePod then started fetching higher prices on resale marketplaces like eBay, and Apple decided to release a second-generation full-size HomePod with some slight changes in January 2023.

What's Next?

There have not been any rumors about a third-generation HomePod, but at least two other HomePod products are allegedly in the pipeline.

In a January 2025 edition of his Power On newsletter, Bloomberg's Mark Gurman said that Apple was aiming to release a new HomePod mini "toward the end of the year." He said the speaker will be equipped with an Apple-designed Wi-Fi and Bluetooth chip, but it is unclear if that change will have any consumer benefits. There is no word yet on what other new features are planned, but improved sound quality and a newer chip are safe bets. The current HomePod mini is equipped with the Apple Watch Series 5's S5 chip.

HomePod With Screen Feature
Apple is also rumored to be planning an all-new smart home hub, which has been described as a HomePod with a screen. The device is expected to have a square iPad-like screen that can be attached to a speaker base, or it can be mounted on a wall.

Apple's smart home hub will reportedly feature a 6-inch or 7-inch display, along with an A18 chip. It would allow users to control smart home accessories, make FaceTime video calls, use Apple's intercom feature between rooms in a house, and more. It might even double as a home security system with an Apple-designed smart home camera.

In March, Apple supply chain analyst Ming-Chi Kuo said that the HomePod with a screen would enter mass production in the third quarter of 2025, but it is unclear if it will launch this year or next year. Apple delayed the personalized Siri features that are expected to be at the core of the device, so perhaps next year is a safer bet at this point. However, Apple could still provide an early preview of the home hub at any point now.

The Apple Watch provides highly accurate measurements of heart rate and step count, but their estimates of calories burned can be significantly off, according to a new peer-reviewed meta-analysis conducted by researchers at the University of Mississippi (via CNET).

Apple Activity Rings Graphic
The study reviewed 56 previously published studies evaluating the Apple Watch's performance against gold-standard clinical tools in three core areas: heart rate monitoring, step count tracking, and energy expenditure estimation.

The researchers reported low mean absolute percentage errors (a common metric used to assess measurement accuracy) of 4.43% for heart rate and 8.17% for step counts. These fall within the threshold generally considered acceptable for consumer-grade fitness devices. In contrast, the average error for energy expenditure was 27.96%, more than three times the margin considered acceptable for accurate measurement.

The analysis incorporated data from studies spanning multiple Apple Watch models and user groups. The high error margin in calorie estimation was consistent across all cohorts and forms of physical activity.

These devices are great for keeping track of habits and staying motivated. But do not take every number as 100% truth, especially the calories. Think of it as a helpful guide, not a diagnostic tool. It is useful but not perfect.

The findings align with previous independent evaluations that have raised concerns about the reliability of calorie burn estimates from consumer-grade wearable devices like Apple Watches.

While the Apple Watch has undergone continuous generational improvements since its debut in 2015, the researchers noted that even newer models still exhibit considerable error in calorie estimation. However, the study did observe a trend toward improved accuracy in more recent models:

While we cannot say every update is a big leap forward, there is a noticeable trend of gradual improvements over time. It shows that Apple is refining the technology over time.

The researchers emphasized that their analysis is not intended to discredit the utility of wearables, but rather to clarify their limitations and inform both consumers and smartwatch makers.

By showing where the weaknesses are, we can help developers get real feedback. If they know what needs to be fixed, they can design better sensors or algorithms. Our findings can guide improvements and help make these devices more useful for both everyday users and health care providers.

Apple does not publish the algorithms used in Apple Watch fitness tracking, nor does it claim that the device provides clinical-grade energy expenditure measurements. The company has consistently positioned the Apple Watch as a general wellness tool rather than a medical diagnostic device, though it has introduced several advanced health features in recent years, such as body temperature monitoring and sleep apnea detection.

Apple today announced that four additional games will be added to the Apple Arcade library on Thursday, July 3, including a new Angry Birds title.

Angry Birds Bounce
Angry Birds Bounce is a new take on the iconic Angry Birds game, which has been downloaded billions of times over the years. According to Apple, it combines classic Angry Birds slingshot gameplay with arcade-style brick-breaker mechanics.

Apple's full description of the game:

Join Red, Chuck, Bomb, and the rest of the gang on a brand-new adventure. Angry Birds Bounce combines the classic charm of Angry Birds with an innovative arcade brick-breaker twist. When the pigs take over their islands, the birds must bounce back — literally — combining into powerful flocks and launching themselves to defeat an army of piggies and reclaim their home. With strategic rogue-lite gameplay, each level is a new challenge where players will master precision shots, unlock exciting power-ups, and build unique combos during each run.

All four games that are coming to Apple Arcade on July 3:

More details about all of the games are outlined in Apple's announcement.

Apple also highlighted five games that are launching on Apple Arcade today.

Accessible through the App Store, Apple Arcade is a subscription-based service that provides access to hundreds of games across the iPhone, iPad, Mac, Apple TV, and Apple Vision Pro, all free of ads and in-app purchases. In the U.S., Apple Arcade costs $6.99 per month, and it is bundled with other Apple services in all Apple One plans.
