RESTORE YOUR SPOβ INSIGHTS ON APPLE WATCH SPOβ Watcher is a specialized utility designed for users who want full visibility of their blood oxygen data directly on their wrist. While some devices may not display these readings natively, your sensor is still active and securely recording data to the Apple Health app. SPOβ Watcher acts as the essential bridge, retrieving that data from HealthKit and restoring it to your watch face and dashboard. β KEY FEATURES β β RE-ENABLE WATCH VISIBILITY If you lack a native on-device option to view your blood oxygen levels, our app provides the solution. It pulls the SpOβ data already stored in your HealthKit database and displays it instantly on your Apple Watch. β REAL-TIME DASHBOARDS View your latest blood oxygen percentage at a glance with high-contrast, easy-to-read designs optimized for clarity on the go. β ADVANCED WATCH COMPLICATIONS Personalize your watch face with our specialized "Four Corner" layout. See your current SpOβ value, exact time of measurement, and a smooth historical trend graph without needing to open your iPhone. β 24-HOUR INTERACTIVE GRAPH Visualize your daily fluctuations with a detailed 24-hour history line chart, helping you identify patterns in your respiratory wellness throughout your routine. β AUTOMATIC BACKGROUND SYNC Using intelligent observer queries, the app detects new scans as soon as they reach your Health app, ensuring your watch complications stay updated automatically. β 30-DAY TRENDS Dive deep into your history with comprehensive daily averages, highs, and lows to help you track your long-term wellness journey. β PRIVACY & SECURITY: YOUR DATA STAYS YOURS β We believe your health data is your most sensitive information.
