Description
Blood Oxygen Tracker brings your blood-oxygen, heart-rate, and sleep data from
Apple Health into one clear timeline, with trends, overnight views, widgets,
and notifications for newly synced readings at or below your chosen threshold.
IMPORTANT: An iPhone alone cannot measure blood oxygen. Automatic SpO2 import
requires a compatible Apple Watch or a pulse oximeter whose app writes readings
to Apple Health. Blood-oxygen features and availability vary by device, country,
and region. You can also log readings manually and estimate your heart rate using the iPhone camera.
