SPO2er gives you a clear, easy-to-understand view of your blood oxygen levels throughout the day. Using data already stored in the Health app, SPO2er displays your latest reading, 24-hour trends, high/low values, averages, and a complete history, both on your iPhone and Apple Watch. There are no accounts, no ads, no servers, and no external data sharing. All information comes directly from HealthKit and stays securely on your device. Features: • Latest Blood Oxygen Reading See your most recent SPO₂ measurement, formatted clearly with the exact time it was taken. • 24-Hour Trend Graph View an elegant sparkline showing how your SPO₂ changed over the past day, with high, low, and average values. • Detailed History Scroll through a timestamped list of SPO₂ samples from the last 24 hours. • Apple Watch Complications Choose from multiple complications that update automatically when new readings are available, so your most recent value is always just a glance away. • Red Highlighting of User-Set Low Values Set the lower threshold you want for highlighting SPO₂ values viewed on the Watch, Complication or SPO2er app on the iPhone. • iPhone ↔ Watch Sync Your iPhone reads SPO₂ data from the Health app and delivers it directly to the watch app and complications. • No Sensors Accessed SPO2er does not measure blood oxygen. Instead, it reads the data you already have in the Health app, whether from Apple Watch, compatible third-party monitors, or other HealthKit-enabled devices. Why SPO₂ Tracking Matters Many wellness devices record blood oxygen throughout the day and night. SPO2er helps you keep an eye on overall trends, see how values vary, and stay more aware of changes, all using the health data you already collect. Privacy-First Design Your health information stays entirely on your device. SPO2er does not collect, transmit, or store data on any server. Permissions are used solely to read blood oxygen values from the Health app. For Anyone Who Uses HealthKit SPO2er works with: • Apple Watch models that support blood oxygen • Third-party SPO₂ monitors that write to HealthKit • Wellness devices and apps that sync SPO₂ into the Health app • Manually entered SPO₂ data in the Health app If it’s in HealthKit, SPO2er can display it beautifully.
