Getting started
- Check that blood oxygen readings are available in Apple Health and allow the app to read the relevant health data.
- Review the app's monitoring and alert settings, then enable monitoring when you want to use it.
- Check the reading timestamp and the latest Apple Watch monitoring status rather than assuming a displayed value is current.
Common questions
Where do the blood oxygen readings come from?
The app reads available blood oxygen samples from Apple Health with your permission. It does not perform its own blood oxygen measurement. Reading availability depends on your device, region, system, and permissions.
Why is a reading missing or marked as old?
Check whether Apple Health contains a recent blood oxygen sample and whether the app has access to it. A previous sample is not a continuous live reading. New sample timing is controlled by the device and operating system.
Why did I not receive an alert?
Check monitoring status, the alert settings, and notification permission on your devices. Alerts depend on eligible new readings, your settings, device state, and system delivery. The app cannot guarantee fixed measurement intervals or delivery for every low reading.
Why is my Apple Watch monitoring status different from my iPhone?
Check the most recent Watch status update shown in the app. A monitoring request and a confirmed Watch state are different. Confirm that the devices are paired and the Watch app is installed and available.
How do Premium purchases work?
Purchases are handled by Apple. If an entitlement is missing, check that you are using the Apple Account associated with the purchase and use Restore Purchases if it is available in the app. Manage or cancel subscriptions through your Apple Account subscription settings.
What is included in an iCloud backup?
Optional encrypted backups contain alert times and the thresholds set at those times, not blood oxygen values. Altitude and pressure history can optionally be included. Keep the password safe: the app does not store it and cannot recover a backup without it. Restoring alerts requires renewed Apple Health access and matching readings.
