watchOS 26 brings a fresh look and smarter health tools to the wrist. It gains updated Smart Stack prediction algorithms, a new Workout Buddy mode, and an overhauled Workout app interface for easier tracking. Moreover, the update introduces a Liquid Glass design overhaul that aligns watchOS with iOS and iPadOS aesthetics .
Supported Devices
Apple confirmed that watchOS 26 will roll out this fall as a free update for Apple Watch Series 6 or later, the second-generation Apple Watch SE, and all Apple Watch Ultra models . These devices will receive the core watchOS 26 features once paired to a compatible iPhone.
Pairing and Prerequisites
To install watchOS 26, users must pair their watch with an iPhone 11 or later running iOS 26. Therefore, older iPhone owners should check device compatibility before attempting the upgrade .
Apple Intelligence Requirements
Some advanced watchOS 26 features rely on on-device AI. For instance, Apple Intelligence enhancements require an iPhone 15 Pro, iPhone 15 Pro Max, or any iPhone 16 model. Consequently, users with those handsets will enjoy deeper Siri integration and context-aware suggestions on their watches .
Wrist Flick Gesture Exclusives
Apple also added a convenient “wrist flick” gesture to mute calls and notifications. However, this feature remains exclusive to Apple Watch Series 9, Series 10, and Apple Watch Ultra 2, reflecting the need for enhanced motion sensors in newer hardware .
Why It Matters
By focusing compatibility on devices with more powerful chips and better sensors, Apple ensures that watchOS 26 runs smoothly. Furthermore, narrowing support simplifies testing and speeds up security updates. As a result, developers can embrace the new APIs and design guidelines knowing their apps match the latest watchOS standards.
Users eager for the update should back up their watches, then watch for the public release this September. Once available, installing watchOS 26 will unlock Apple’s biggest watchOS redesign and feature set in years.
