Apple Releases iOS 27.3 Beta With New Health App

Apple released the first beta version of the iOS 27.3 operating system to developers on November 4. The update once again tests the new AI-powered Health app. The app had previously been removed from the iOS 27.2 beta without explanation. The new Health app will be released to all users next month.

The Insights section provides an overview of heart health, sleep, fitness, key health metrics, and the menstrual cycle throughout the day. The For You section offers advice tailored to daily habits. For example, if a user’s sleep is disrupted for several nights in a row, the app may recommend changing their bedtime routine. It also includes videos and articles prepared by clinical experts.

The Longevity section analyzes how heart health, sleep, mental well-being, movement, metabolism, hearing, and nutrition metrics change over time. The Health Age feature uses Apple Watch data to show how the body’s condition compares with its age. Users can also add laboratory results such as A1c and LDL cholesterol to the app. During at-home movement assessments, the iPhone camera and Apple Watch measure flexibility, strength, balance, and movement. The data is processed on the device itself, and no video is recorded, stored, or shared.

The Gym Strength feature added to Apple Fitness+ creates personalized 4-week strength training plans. Each plan is tailored to the user’s experience, goals, schedule, and the equipment available at the gym. Users can choose workout days, muscle groups, and workout duration. The system recommends exercises, numbers of sets and repetitions, and how much weight to lift, while also showing short videos. The plan changes based on previous results, and metrics can be recorded with Apple Watch.

Vertical tabs and an adaptive dark mode have been added to the Safari browser. Vertical Tabs displays open pages on the left side of the screen as icons or with their full titles. The feature can be enabled in the Safari section of the system settings. Adaptive Dark Mode automatically changes the appearance of websites that do not have a dark mode.

The AI-powered Siri AI can now perform more complex tasks in phone apps. Users can ask it to organize files, schedule a message for a specific time, and create a personalized music playlist. The new commands work in the Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts, and Weather apps. For now, this feature is limited to Apple apps.

StandBy mode now offers new options for changing the appearance of analog and digital clocks. Separate screens for the calendar and weather have also been added. In photo mode, users can select shared albums and swipe between views. iPhone Duo users will be able to swap the left and right sides of the screen using the Reachability feature. Health will support more languages. Traditional Chinese, Vietnamese, Turkish, and Norwegian will also be added for Siri AI.
