Apple in ‌iOS 16‌ and watchOS 9 is adding an AFib history feature for those who suffer from atrial fibrillation, with the aim of tracking how long a person has had atrial fibrillation and how often.

iCloud Shared Photo Library

The third beta of ‌iOS 16‌ introduces support for iCloud Shared Photo Library, which is designed to make it easier for you to share photos with friends and family members. You can invite up to five people to share a photo library with you, and all participants can add, delete, and edit images.

Lock mode

Added as an extreme security measure, Lock Mode is available in ‌iOS 16‌, ‌iPadOS 16‌, and macOS Ventura. This is an optional security feature that is intended to protect a small number of high-level users who are exposed to targeted cyberattacks by state-sponsored spyware.

Lock mode functionality

Lockdown mode is intended for journalists, activists, government employees, and others who may be targeted by sophisticated cyberattacks. It’s not for the everyday user and it limits many iPhone features. In Messages, for example, attachments other than pictures are blocked, and in FaceTime, calls from people you haven’t contacted yet are blocked.

Complex web technologies and browsing features are blocked in web browsers, shared albums are removed from the Photos app, wired connections are blocked, and configuration profiles cannot be installed. You can find more information about lock mode in our article describing the feature.

Lock screen time font

There are now 12 fonts to choose from on the ‌iOS 16‌ Customizable Lock Screen right now, including an option that’s thinner than previous fonts and another that’s a thicker version of the previously available serif font.

Calendar lock screen widget

For privacy reasons, the Calendar Lock Screen widget no longer provides details about the next upcoming event when the ‌iPhone‌ is locked. It scrambles information until the ‌iPhone‌ is unlocked by its owner.

There’s a new “Include Due Today” option in the Settings section of the Reminders app. It’s designed to include both overdue and due today items in the badge count, rather than just items due today.

Earth lock screen wallpaper

With Earth Lock Screen wallpaper, widgets will no longer block the view of the earth. The Earth image moves down when widgets are in use, and up if there are no widgets placed. In previous beta versions, widgets overlapped.

iOS version interface update

In the Settings app under About > iOS version, if you tap on the version number, the interface has been updated. It’s simpler and no longer a pop-up card, and there’s no longer a link to Apple’s security website.

Clownfish Wallpaper

Some iOS 16‌ users who have the third beta installed are seeing a Clownfish wallpaper option. This wallpaper was on the original ‌iPhone‌ when it was introduced by Steve Jobs in 2007, but it was never officially launched. It doesn’t appear for everyone, but it might be added as a wallpaper option in a future beta.


On the iPad there is a new start screen for the Stage Manager function. There are also new tutorials to show you how to use it, plus an updated multitasking menu with improved labeling.

iCloud Start Screen

When you choose an iCloud+ subscription option, a new splash screen explains the features.

Virtual card support

‌iOS 16‌ adds virtual card support for shopping with Safari. Some banks and card providers allow customers to generate virtual card numbers (similar to how the Apple Card works) to use online to avoid having their credit card details stolen. Safari in ‌iOS 16‌ will support this feature based on beta code.
