Technology Desk

In Short: MacRumors has compiled a comprehensive guide to iOS 27 and the new Apple Watch, highlighting major updates and lesser-known changes.

When iOS 27 first came out in June, MacRumors began working on a series of in-depth feature guides and how-to articles to cover all the updates in Apple's new software. Their ultimate guide aggregates all of this coverage, making it useful for both new and existing iOS 27 users.

The guide includes a complete overview of all new features in iOS 27, along with how-tos that walk you through using these features. Additionally, it highlights new features and lesser-known changes for those upgrading to iOS 27.

Apple's latest Apple Watch, the Ultra 4, features a new Health Sensing System for more accurate heart rate readings, faster performance, and a longer battery life. It also includes Audio Intelligence features, though Apple assures that raw audio is processed separately from the rest of the system before deletion.

In a press release, Apple called the Apple Watch Ultra 4 'the ultimate sports and adventure watch,' with support for a new Health Sensing System that provides continuous heart rate readings. The watch runs on the new S11 chip, which will power new Audio Intelligence features later this year.

The inaugural World Athletics Ultimate Championship, which begins in Budapest on Friday, features a clash between Great Britain's Josh Kerr and Norway's Jakob Ingebrigtsen in the men's 1,500m, and Great Britain's Keely Hodgkinson and Switzerland's Audrey Werro in the women's 800m.
