'Biggest shake-up in a decade' could be coming to your iPhone, iPad, and Mac as Apple plans HUGE reveal today

What can we expect when Apple CEO Tim Cook takes to the stage for this year's keynote? Unsurprisingly, Apple isn't revealing anything about its plans. Known for its secrecacy, the only clue about what's in the works from the US technology firm is the tagline "Sleek Peek" that appears on the invitation sent out to developers.

Thankfully, there are a few whispers about what we might see at WWDC.

According to Bloomberg's Mark Gurman, Apple is planning a major redesign of all of its operating systems. Yes, whether you own an iPhone, iPad, Mac, or Apple Watch, your gadgets will be treated to a complete overhaul with an emphasis on transparent, frosted glass-like menus designed to simplify navigation and modernise the look.

Whispers suggest that light will play a key role throughout the interface.

It's tipped to be the most dramatic software overhaul from the teams within Apple since iOS 7 launched back in 2013.

For clues about exactly what this rumoured redesign will look like, look no further than the software running on Apple Vision Pro. This £3,500 Spatial Computer uses circular icons for applications and translucency throughout the operating system to overlay windows and panels on top of the real world.

Given the Apple Vision Pro is the first new device in an all-new product category since the launch of the Apple Watch 10 years ago, it makes sense that this product sets the look for the next evolution of iOS, macOS, iPadOS, and watchOS.

According to whispers, the complete reworking of Apple's software could pave the way for new devices, like touchscreen-equippd MacBooks, smart home hubs like the Echo Show or Google Nest Hub, as well as foldable iPhone and iPad variants, to name just a few possibilities.

Sources speaking to Bloomberg have described the top-to-bottom redesign as "one of the most dramatic software overhauls" in the history of Apple. Device owners should expect "greater transparency and new types of windows and buttons — and that should make all Apple devices feel more consistent and familiar".

The redesign will even extend to CarPlay, ensuring your in-car experience matches your other devices.

Alongside the shiny new visuals, Apple is expected to abandon its current numbering system. Taking inspiration from the automotive industry, Apple will abandon its current numbering system — iOS 18, watchOS 6, iPadOS 18, and VisionOS 2 — to unify everything under the number of the next year.

If accurate, that means the next releases will be iOS 26, iPadOS 26, macOS 26, tvOS 26, and visionOS 26.

Beyond the refreshed look and the new name, iPhone owners can expect to be treated to a slew of new features. Apple will rework the Phone app, which'll offer a new optional view that "combines favorite contacts, recent calls and voicemails into a single, scrollable window," according to Bloomberg.

Apple's Camera app will be reworked to declutter the interface, which has become increasingly overloaded with the addition of new features like Spatial Video, Cinematic Video, Slow-Mo, and Panorama.

iMessage will unlock the ability to send polls across all devices. Following in the footsteps of WhatsApp, Apple is rumoured to add background wallpaper to each conversation that syncs across devices.

Two brand new apps will purtpoedly be coming to iPhone and iPad with the next update — a dedicated Games app that brings together everything you need to share high scores with friends and play competitive modes. It'll have dedicatyed tabs for Home, Arcade, Play Together, Library and Search.

The Preview app — a staple on macOS for annotating and managing PDFs — will be making the jump over to iPhone and iPad to sign documents, edit PDFs, and more.

Elsewhere, Apple is expected to make battery life improvements that relies on AI to adapt to your usage patterns. The Shortcuts app will integrate Apple Intelligence for creating quick actions, while Genmoji — introduced last year at WWDC — will allow you blend existing emojis together into a brand-new creation.

A convenient Wi-Fi synchronisation feature means logging into a hotel Wi-Fi connection on your iPhone will automatically connect your iPad and Mac to the same network.

An update to Apple AirPods will unlock real-time translation for in-person conversations, with your paired iPhone handling the data crunching — translating spoken words and your responses back into the other language. Live translation will also be extended to phone calls and text messages across all Apple's operating systems.

iPadOS 26 will unlock multi-tasking features, bringing it much closer to a Mac-like experience. However, some of this functionality will only kick-in when you attach Apple's Magic Keyboard accessory.

The next iteration of visionOS will allow Apple Vision Pro owners to use eye-scrolling mon webpages, documents, and more, It'll also add support for third-party VR controllers, bolstering the headset's capabilities as a gaming device.

Rounding out the rumours, Apple Watch looks set to unlock some Apple Intelligence features to offer new insights into your health, heart-rate, and other core metrics measured by the wrist-worn gadget.

As always, it's worth taking everything with a pinch of salt until Apple execs. take to the stage in Apple Park.

Whatever the teams inside Apple have been working on, there's not long left to wait until we find out.
