At its autumn product launch event, Apple announced a major redesign of its core digital health platform, the 'Health' app. Leveraging multimodal biosensor data from the latest generation of Apple Watch and smartphones, the new health application introduces a dynamic 'Health Age' calculation model and a comprehensive 'Body Readiness' scoring system. This marks Apple's upgrade in the field of personal health monitoring, from traditional vital sign recording to systematic physiological state analysis and recovery guidance.
