About

BloodOxygenMonitor

Features
Read full description

Review blood oxygen readings available in Apple Health, see when they were measured, and set a personal alert threshold. BloodOxygenMonitor brings readings, trends, and monitoring status to iPhone, iPad, Apple Watch, and widgets. READINGS AND TRENDS View available readings, measurement times, charts, and summary statistics. Older readings are clearly marked. Explore night reports and review how your readings change over time. THRESHOLD ALERTS When monitoring is active, the app can alert you when an eligible new reading falls below your threshold. Choose your alert preferences and review alert history with measurement times, alert times, and thresholds when available. Monitoring requests remain pending until Apple Watch confirms the change. HISTORY AND EXPORTS Filter records by date and export selected data for your own records. Use widgets to check available readings and trends at a glance. PRIVACY AND OPTIONAL BACKUP The app reads blood oxygen data from Apple Health with your permission. Alert history stays on your device by default. You decide when to create a password-protected iCloud backup. Alert backups contain only measurement times and thresholds; optional altitude and air pressure history is encrypted with the same password. You keep the password, and it cannot be recovered if lost. Apple Health measurements are managed separately in the Health app. AVAILABILITY Requires iOS 18.5 or later. The companion Watch app requires watchOS 11.5 or later. Blood oxygen availability depends on the Apple Watch model and region. The app reads available Health data; it does not take independent blood oxygen measurements. Readings, synchronization, and alerts depend on permissions, device settings, connectivity, and system delivery, and may be delayed or unavailable. Some features require an in-app purchase. FOR GENERAL WELLNESS This app is not a medical device and is not intended for diagnosis, treatment, or emergency medical alerts. Consult a qualified healthcare professional about symptoms or health concerns.
