According to new leaked information, watchOS 27 will be upgraded with heart rate tracking capabilities.
Apple is also said to be adding new watch faces, including a variant of the "Modular Ultra" interface that was originally exclusive to the Apple Watch Ultra.
Some features related to Apple Intelligence may also appear on watchOS 27 when connected to new iPhone lines such as iPhone 15 Pro and above. Currently, watchOS 26 has supported features such as notification summaries, live translation in messages or Workout Buddy exercise assistant.
In addition, Apple is said to be expanding satellite connection capabilities on smartwatches. New features may include using satellite maps or sending photos in satellite messages on the Apple Watch Ultra 3 without relying on the iPhone.
The new report also states that watchOS 27 will not focus on "revolutionary" changes, instead prioritizing bug fixes, performance optimization, and improved daily user experience.
