It's about time Apple got a Readiness score to compete with Fitbit and Garmin — but I'm disappointed it's not coming to the Series 11

Apple Watch Series 12 and Ultra 4 will introduce a new feature called 'Readiness' to watchOS, a concept that Google, Fitbit, Garmin, and others have had for years. This feature takes various data points such as heart rate, sleep, exercise, and rest and converts them into a single, easy-to-understand number, the 'Readiness Score'.

This score indicates the body's preparedness for the day ahead, with lower scores suggesting a need for rest and higher scores encouraging continued activity. Apple Watch's latest models boast the most accurate heart rate sensing in a wearable due to advanced sensor technology that enhances heart rate readings and heart rate variability at night.

The feature also integrates with the Vitals app, which arrived with watchOS11, to help users identify health trends and understand the body's response to various activities. Despite the reviewer's love for the Apple Watch and their current model, the 'Readiness' feature could be the final push needed to upgrade to the Series 12 or Ultra 4.
