iOS 11.3 Coming This Spring With New Animoji, Vertical ARKit, Health Records, Battery Info, and More
iOS 11.3 introduces new Animoji on the iPhone X, including a lion, bear, dragon, and skull. There will now be 16 characters to choose from in total, including existing ones like a pig, fox, chicken, pile of poo, and robot.
iOS 11.3 will feature ARKit 1.5. In addition to horizontal surfaces like tables and chairs, Apple's updated augmented reality platform will now be able to recognize and place virtual objects on vertical surfaces like walls and doors, and more accurately map irregularly shaped surfaces like circular tables.
ARKit 1.5 can find and recognize the position of 2D images such as signs, posters, and artwork, and integrate these real-world images into augmented reality experiences, such as bringing a movie poster to life. In addition, the view of the "real world" will now be in 1080p HD, up from 720p currently.
The software update will introduce Business Chat, a new way for users to communicate directly with businesses within the Messages app. This feature will launch in beta following the public release of iOS 11.3 this spring, with support from select businesses, including Discover, Hilton, Lowe's, and Wells Fargo.
With Business Chat, it's easy to have a conversation with a service representative, schedule an appointment or make purchases using Apple Pay in the Messages app. Business Chat doesn’t share the user’s contact information with businesses and gives users the ability to stop chatting at any time.In the Health app on iOS 11.3, users will be able to view health records, including available medical data from multiple providers like Johns Hopkins and Cedars-Sinai. The data is encrypted and protected with a passcode.
iOS 11.3 will provide users with an iPhone 6 or newer with more information about the health of their device's battery, including a recommendation if it needs to be serviced. In the same menu, it will also be possible to see if Apple's power management feature is active and turn it off if desired.
Apple says the battery and power management features will be coming in a later iOS 11.3 beta release, so they won't be available today.
Other new iOS 11.3 features include more prominent placement of music videos in Apple Music, a new Video section in the "For You" tab of Apple News, and support for Advanced Mobile Location (AML) to automatically send a user's current location when making a call to emergency services where supported.
The first beta of iOS 11.3 will be seeded to developers later today, followed by a public beta soon. The software update will be released to the public this spring for iPhone 5s and newer, all iPad Air and iPad Pro models, the fifth-generation iPad, iPad mini 2 and newer, and the sixth-generation iPod touch.
Update: Apple has seeded the first beta of iOS 11.3 to developers.
