Apple (AAPL) on Wednesday debuted its latest Apple Watch Series 11 and Ultra 4 and AirPods 5 as part of its annual fall event.
The $399 Apple Watch Series 12 and $799 Apple Watch Ultra 4 get improved heart rate-tracking sensors that take heart rate readings every 5 seconds and track heart rate variability.
The company said it tested the new tracking sensor against competing trackers and a chest strap, and found it to be the most accurate.
Apple is also announcing a new readiness feature in the Apple Watch or Fitness app, similar to those seen in products from Oura and Fitbit. The feature, the company says, analyses your recent activity, vitals, and sleep to provide you with a daily score that indicates whether you should rest, pace yourself, or work out as usual.
