HR & SpO2 - Companion App

* Description of the iPhone Companion App Specially optimized for the US version of Apple Watch, which cannot read the watch's local blood oxygen data. It adds the function of synchronizing health data between iPhone and Apple Watch. US version users should uninstall the standalone Apple Watch App first before using this companion App, and keep both apps running in the background during use. Non-US versions of Apple Watch will automatically read the local blood oxygen data without extra settings. Core Highlights Two Indicators in One, Everything at a Glance - Dual Display: Fused display of heart rate and blood oxygen. Turn the Digital Crown within the main App to switch views smoothly, saying goodbye to rummaging across multiple Apps. - All-Style Complications: Exquisite widgets reside on your watch face. Mix and match heart rate, blood oxygen, or dual-indicator combinations freely. Your health status is known at a turn of the wrist. - Complete Records: Instantly read real-time heart rate and blood oxygen. Tap the data range to scan fluctuation intervals for today, past 4/12/24h, and past week right on your wrist (resting/walking averages included). - Blood Oxygen Alert: When blood oxygen saturation drops below the preset value, the Apple Watch App triggers a striking visual change, haptic feedback, and push notifications for quick assessment. Touchable Native Texture, Liquid Glass Aesthetics - New-Generation Native UI: Built on the latest watchOS. Utilizing fully native controls and a unique liquid glass visual effect, the interface is transparent, lightweight, and elegantly integrated. - Vivid Immersive Animation: The heart rate page pulses synchronously with your heartbeat (long press for an immersive pulse rhythm). The blue halo of blood oxygen flows like breathing, changing colors to alert you. Deeply Integrated into the Apple Watch Ecosystem - Watch Face Adaptation: Perfect support for various complication styles (corner, circular, textual, and rectangular) to fit your personalized layout perfectly. - Elegant Always-On Display (AOD): Supports AOD dimming. Intelligently hide backgrounds and animations to save power while retaining core data. It wakes up instantly when you raise your wrist. - Smart Stack Linkage: Perfect support for watchOS Smart Stack. Core data of heart rate and blood oxygen is efficiently presented at all times, coexisting harmoniously with other cards. Pure Local Execution, Protecting Your Privacy - Native HealthKit Access: Directly read official health data from Apple Health. - Pure Local Secure Processing: All data is analyzed and rendered only locally on the device, with no uploads, no tracking, and no server caching. Privacy is rock-solid. Exclusive Features of the iPhone Companion App The same fusion widget style as the Apple Watch face allows for quick reading of health information right on the iPhone lock screen. Four sizes of heart rate, blood oxygen, and fusion chart home screen widgets display complete health data for the past 4/12/24 hours and the past week. The Smart Stack chart widget supports fusion data and keeps settings synchronized and updated with the iPhone. Low blood oxygen notifications can be adjusted freely between 85% and 95% via the iPhone companion App to meet the needs of different scenarios. Let Heartbeats Have a Rhythm, Let Breathing Have Color This is a piece of liquid glass aesthetic art that accompanies your wrist at all times. Every lift of the wrist is a visual enjoyment; every pulse is a guardian of health. Fuse the dual indicators now and start your exclusive futuristic health aesthetics. * The data provided by this App is for daily health management reference only and does not possess medical diagnosis functions.
