Apple's Readiness score is a daily recovery metric built into the Apple Watch Series 12 and Ultra 4, featuring a 0-to-10 score based on recent activity, training load, vital signs and sleep. The feature relies on redesigned optical and electrical heart sensors with larger green LEDs to power its measurements. It calculates heart rate readings every five seconds and measures heart-rate variability every five minutes, feeding overnight HRV into a personal baseline so the score can be revised as new data arrives.
The Readiness experience packages guidance that ranges from recovery to increased activity and is positioned as Apple’s answer to recovery-focused fitness tracking. The score is unavailable on Series 11, Series 10, Series 9, Ultra 3 and Ultra 2 despite those models running the same watchOS.
The most data-dense recovery coaching is tied to specific hardware that samples vitals more frequently. Owners of recent pre-Series 12 watches keep core tracking but will not receive Readiness unless they move to the models with the new sensors.
