Wish it were easier to see whether you’ve met your Stand Hour yet? This app uses your HealthKit data to offer complications for your favorite Apple Watch faces that show your Activity Rings, plus a Stand Hour circle to show whether you’ve already earned it at a glance. Note: If the app is missing on your Watch after purchase, go to the App Store on your Watch to install. (Scroll to the bottom, click Account -> Purchased, and tap the download cloud next to Activity Rings+) - APPLE WATCH APP In the app, see a quick view of your Move/Exercise/Stand data and your familiar Activity Rings, with an added indicator showing whether you've met the current Stand Hour. Also see today's Steps at a glance—no more scrolling down to interpret your activity data! Tap the screen to switch to percentage view or Calories/Minutes/Stand Hours remaining. - COMPLICATIONS On newer Apple Watch faces (Meridian, Infographic, California, etc.), you can add complications that feature your Activity Rings with an added stand indicator that illuminates when you've met the current stand hour. On older Apple Watch faces, (Breathe, Modular, Colors, Simple, etc.), you can add a Stand Indicator that will be colored solid if you've met the current stand hour or will be a hollow outline if you still need to stand up. Note: Complications refresh in the background as often as Apple permits. Tap the complication to open the app if you'd like to refresh the data immediately. Your Stand Hour will always clear at the start of the next hour, so if you see Activity Rings+ lit up, you'll know you've hit it. If you have any issues with HealthKit permissions, make sure to grant permissions from your iPhone via Settings -> Privacy -> Health. If complications are not available immediately after installation, rebooting your Apple Watch usually does the trick!

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. — IMPORTANT DISCLAIMER — This app is intended for fitness and wellness purposes only and is not a medical device. It is not intended for the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease. Always seek the advice of a physician or other qualified health provider with any questions regarding a medical condition. — TECHNICAL REQUIREMENTS — ● Requires Apple Watch Series 6 or later (excluding SE) with Blood Oxygen sensor. ● Requires authorization to access Oxygen Saturation data in the Apple Health app.
