Apple’s (AAPL) WWDC developers conference, arguably its biggest event of the year, kicks off next Monday, and it’s expected to bring a slew of changes to the software that powers each of the tech giant’s devices.

We’re talking updates to Apple’s iOS, iPadOS, watchOS, and perhaps, the debut of the company’s long-rumored realityOS for VR and AR headsets.

Yahoo Finance will be covering WWDC live as it unfolds, but just as with any big Apple event, I’m already getting questions about what consumers can expect from the show and how it will impact them.

So to that end, here’s why you should pay attention to Apple’s WWDC.

Apple’s AR/VR software and headset

The most anticipated and perhaps most up-in-the-air announcement at WWDC is the debut of Apple’s realityOS and accompanying headset.

Apple has reportedly been working on the software powering its AR/VR headset for years, and with competitors like Meta already in the market, Apple could finally give us a look at what it has up its sleeves when it comes to its AR/VR plans.

Updates for your iPhone and iPad

Yep, your iPhone is getting an updated look thanks to some big changes coming via iOS 16. According to Bloomberg’s Mark Gurman, who seemingly lives in the walls of Tim Cook’s office, iOS 16 will feature upgrades to the iPhone’s lock screen and new widgets.

Android phones have offered similar features for some time, so it’s not exactly a new capability, but iPhone owners tired of having to unlock their devices to check out their latest notifications or look up the weather will likely enjoy it. That said, the lock screen update may only be something available to iPhone 14 users.

Gurman also points to improvements to iOS’s Messages app, including more social media-style updates, as well as changes to the systems’ notifications.

Back in January, Twitter user @LeaksApplePro showed off some of the larger widgets that Apple will bring to the iPhone with iOS 16, and they certainly look like they’ll be rather useful, allowing users to access multiple app features at once including changing music and using the camera flash as a light..

Apple’s iPadOS 16 is also said to get new multitasking capabilities that could make the iPad even more of a laptop competitor. It’s still not as useful as using a full-on MacBook in certain situations, and it’s unlikely Apple will ever bring the two into direct competition, so don’t expect to be able to open and move around a multitude of different app windows.

The Apple Watch may get better battery life

The Apple Watch is the world’s best-selling smartwatch, and for good reason. It marries a stellar design with fitness tracking and messaging capabilities. Apple is expected to show off its latest version of the software that powers the watch, watchOS 9, during WWDC with the hope that it will improve the wearable’s battery life.
