Apple just announced watchOS 26, the latest version of its Apple Watch operating system, at WWDC 2025. watchOS 26 is the follow-up to last year’s watchOS 11 release, but Apple has jumped its numbering up to match the upcoming year in a bid to standardize its operating system names, so that the watchOS numbering now matches iOS, macOS, and Apple’s other software platforms. The Apple Intelligence-powered Workout Buddy uses workout and fitness data to generate not only personalized insights and advice, but pep talks, too. Apple Music will also do its best to recommend playlists based on the type of workout you’re doing and what it knows about your taste. Live Translation will work in Messages so long as both your Apple Watch and iPhone are sufficiently recent and powerful.
