Enhanced Health Connect Integration

Through deep integration of the Android Health Connect framework, seamless data synchronization across 50+ mainstream fitness apps has been achieved. Users no longer need to export data manually, resolving the pain point of health data silos across multiple platforms and significantly improving data integrity.

AI-Powered Wellness Insights

Machine learning-based personalized trend analysis has been introduced. By analyzing the user's sleep and heart rate variability (HRV), the updated system can automatically generate personalized recovery recommendations, rather than merely displaying raw data, providing users with valuable insights for decision-making.

Wear OS Hybrid Sync 2.0

The real-time two-way synchronization algorithm between the smartwatch and the phone has been optimized. Power consumption has been reduced by 15%, while the recognition delay for High-Intensity Interval Training (HIIT) has been shortened to the second level, greatly improving the real-time performance and accuracy of sports monitoring.

Refined Goal Management System

Updated the Heart Points calculation model to accommodate a wider variety of modern exercise types (such as meditation and Pilates). This inclusive update ensures users receive reasonable motivational feedback at different fitness stages.

Privacy & Transparency Dashboard

A centralized privacy management interface has been added. Users can precisely control the sharing permissions for each health metric, complying with the latest data protection standards and enhancing user trust in the application's security.
