The Apple Watch is to allow female users to track their menstrual cycle from the device for the first time.
A new cycle track feature will allow users to receive alerts when their cycle is about to begin and when they are most fertile.
The new features were unveiled at the tech giant’s annual developer conference, WWDC, in California.
Apple confirmed the next version of iOS, the software used to power the iPhone and iPad, will introduce a dark mode for the first time, making devices easier to use in low-light conditions.
It will also include a range of security and privacy features, including a new “sign in with Apple” tool which will allow users to sign in to websites and services using their Apple ID, rather than using a social media account and sharing personal information.
The feature will give users the option to hide their email address and instead provides a unique, random email address that forwards messages to you rather than giving your personal address to services.
Apple also confirmed a new, separate version of iOS for the iPad.
Called iPadOS, it will allow tablet users to use their device more like a desktop computer, Apple said.
The software will show desktop versions of some websites, as well as use a new version of the Files app that works in a similar way to the Finder file management feature on Apple’s desktop computers.
During the announcements at WWDC, the company also confirmed it was introducing a dedicated App Store for the Apple Watch, which will allow users to search and download apps directly from the wearable device.
