watchOS 27 introduces significant enhancements to fitness and sleep tracking capabilities. The update brings new motivational features to Workout Buddy, offering users progress updates on pace, distance, and workout duration based on their fitness history. Notably, Workout Buddy can now operate independently of an iPhone, providing motivation without the need for a phone. Additionally, it supports Spanish, allowing more users to receive personalized fitness guidance in their language.
Indoor running and walking distance tracking have been improved with more accurate motion tracking algorithms, enabling precise treadmill distance measurement directly from the wrist. Route maps in the Fitness app are also more accurate, offering a clearer view of workout paths.
Sleep tracking has seen improvements, although specific details on these changes have not been disclosed. The update also resolves a step count synchronization issue, ensuring that steps recorded in the Health app are directly synced with the Fitness app.
