Where do blood-oxygen readings come from?

Your iPhone does not measure blood oxygen. The App shows readings from Apple Health, a compatible Apple Watch or pulse oximeter, or values you enter manually.

How does the camera heart-rate feature work?

Place your fingertip gently over the rear camera and flash and keep still during the measurement. The App estimates heart rate from small color changes in your fingertip. It does not take, save, or upload photos or video.

Why aren't my Apple Watch readings appearing?

Confirm that your Watch has synced with the Apple Health app on your iPhone. Then open Blood Oxygen Tracker: SpO2 and use Sync now. You can review access in the Health app under your profile and Apps. Apple Watch may record blood oxygen only on supported hardware and where the feature is available.

How do I change Apple Health permissions?

Open the Health app on your iPhone, tap your profile picture, choose Apps, then Blood Oxygen Tracker: SpO2. You can enable or disable each data type there.

How do I see a family member's readings?

Open More, choose Family, and add the person. You can log readings locally on your iPhone, or invite someone with an iPhone on iOS 17 or later. After they accept and turn sharing on, use the person switcher on Today to see their synced readings.

What does my family member share with me?

With their permission, they share blood-oxygen and heart-rate readings, including the time and source. Sleep data, notes, tags, and location are not shared. Family sharing is not real-time monitoring and should not be used for emergencies.

My family member's iPhone is not on iOS 17

Cloud Family Sync requires iOS 17 or later. You can still add the person as a local family member on your phone and log readings for them manually. Those local readings do not go into their Apple Health record.

The invite link does not open

Confirm that both iPhones use iOS 17 or later, are signed in to iCloud, have iCloud Drive enabled, and can reach the internet. Ask the owner to open More › Family, select the pending person, and send a fresh invitation. A device can accept membership in only one other family at a time.

How do I stop sharing?

On the member's iPhone, open the Family sharing card on Today and choose Stop sharing. The App first removes shared readings, disables future uploads, and leaves the iCloud share. If the phone is offline, keep the App installed and retry when it reconnects.

Who pays for the Family Plan and what do members get?

The family owner purchases and manages the Family Plan. Invited members receive the App's Plus features through that subscription while their membership and the owner's plan remain active; members do not need to purchase or restore it themselves.

How do I restore my subscription?

Open any premium feature to show the subscription screen, then tap Restore Purchases. Make sure the device is signed in to the Apple ID used for the original purchase. A Family Plan is restored on the owner's device; invited members do not need to restore it.

How do I cancel my subscription?

Open iOS Settings, tap your name, then Subscriptions. Select Blood Oxygen Tracker: SpO2 and choose Cancel Subscription. Deleting the App does not cancel a subscription.

How do I delete my data?

You can delete a reading created by the App from its Reading detail screen; the App also removes that reading from Apple Health. Review or delete other Health records in the Health app. Removing a family member deletes that person's shared readings from your device and iCloud share. Uninstalling the App removes its local data, subject to device backups, but does not automatically remove records from Apple Health.

How do I share a report?

Open Reports, choose the date range and details to include, generate the report, and tap Share. Nothing is shared until you explicitly choose a destination in the iOS share sheet.
