Blood Oxygen SpO₂ Tracker

About this app

Blood Oxygen SpO₂ Tracker presents existing blood oxygen (SpO₂) readings from Apple Health on iPhone and Apple Watch. Review the latest available value, spot trends, and understand your history in a focused interface. Features: • Latest available SpO₂ reading on iPhone and Apple Watch • History with daily values, 7-day averages, and min/max views • iPhone widgets and Apple Watch face complications • Optional notifications for readings below your chosen threshold • Views for outliers and value distribution • Barometric pressure and altitude context for personal interpretation How it works: The app requests read-only access to Blood Oxygen in Apple Health. To display values, compatible SpO₂ samples must already exist in Apple Health. Blood oxygen measurement availability depends on device and region. Important: The app does not measure SpO₂, is not a medical device, and does not diagnose, treat, cure, or prevent any condition. Information is for general wellness only and is not medical advice. Consult a qualified healthcare professional with health concerns. Premium: Some features require Premium, available through auto-renewable monthly or yearly subscriptions or a one-time lifetime purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel them in your Apple Account settings, and restore purchases in the app. Privacy Policy: https://bernhardhering.de/privacy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Time-range controls and environmental details now reliably use the app’s language. Air-pressure and high-altitude information is localized correctly as well.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
