SpO2 Watcher

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. SPO₂ Watcher is built with a Privacy-First architecture:

● ON-DEVICE STORAGE: All your blood oxygen data is stored locally on your iPhone and Apple Watch.
● NO CLOUD BACKENDS: Your data stays in the secure Apple Health database on your device. We do not have a backend; your data is never "in flight" to a third-party server.
● END-TO-END ENCRYPTION: Your health information is encrypted whenever your device is locked.
● NO DATA SELLING: We strictly follow Apple’s developer guidelines. Your health data is never shared with advertisers or data brokers.


— WE DO NOT USE YOUR DATA —

Your data belongs to you. SPO₂ Watcher does not collect, store, or transmit your health information to any external location. The app simply requests permission to read "Oxygen Saturation" from the Apple Health app for the sole purpose of displaying it locally on your device. We have no access to your data, and we do not track your usage.
