Apple Watch Series 12 and Ultra 4 also hit shelves Friday. The story here is not a new case shape. It is a Health Sensing System that samples heart rate every five seconds and HRV as often as every five minutes, then turns that into a daily Readiness score.

Audio Intelligence is the other half: Live Rewind can surface the last 15 seconds of a conversation as text, and Siri Recap can summarize talks you opt into. Series 12 still starts at $399. Ultra 4 stays at $799. Audio Intelligence is not available in the EU at launch.
