RESTORE YOUR SPO₂ INSIGHTS ON APPLE WATCH SPO₂ 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. SPO₂ Watcher acts as the essential bridge, retrieving that data from HealthKit and restoring it to your watch face and dashboard. — KEY FEATURES — ● 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 SpO₂ data already stored in your HealthKit database and displays it instantly on your Apple Watch. ● 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. ● ADVANCED WATCH COMPLICATIONS Personalize your watch face with our specialized "Four Corner" layout. See your current SpO₂ value, exact time of measurement, and a smooth historical trend graph without needing to open your iPhone. ● 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. ● 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. ● 30-DAY TRENDS Dive deep into your history with comprehensive daily averages, highs, and lows to help you track your long-term wellness journey. — PRIVACY & SECURITY: YOUR DATA STAYS YOURS — We believe your health data is your most sensitive information.

When I installed the SPO2 app on iPhone, it initially synced from Health app correctly to Watch. But after I requested a manual reading of oxygen using the Apple’s Blood Oxygen app on Watch, SPO2 later showed zero data. It showed the correct time for last update, but showed “0%” data. The Health app showed correct updated data and so did the iPhone version of SPO2, but Watch data was zero. So I tried pressing “Sync Now” but that did not help. I tried rebooting both Watch and iPhone. This did not work. I tried removing the SPO2 app and reloading. This did not work. Only the iPhone SPO2 app works, but not the Watch version. Sorry, but you need more work to do on this. Let me know if and when you fix. ### 1/5 — Does not work *2026-02-07* Does not sync data to the watch. Also doesn’t allow you to use on watch faces.
