Features & Capabilities

Blood Oxygen SpO2 Tracker displays your SpO2 readings from Apple Health on iPhone and Apple Watch. It provides the latest reading, widgets for quick checks, and historical views with daily values, 7-day averages, and min/max charts to review trends at a glance.

Notes: Your data stays on-device for privacy. This app does not measure blood oxygen itself and is intended for personal wellness tracking, not diagnosis. It requires Apple Health data and an Apple Watch Series 6 or newer; low-value alerts are optional and can use a custom threshold, with altitude and barometric pressure context to aid interpretation.

Most reviews indicate the app frequently does not work, with users reporting no oxygen readings or data, and compatibility problems across Apple Watch models (often requiring Series 6). Many customers also describe difficult or unavailable refunds, and complain about unclear pricing and monthly charges. Data presentation issues, such as unreadable graphs, compound the problems. Overall, the most mentioned concerns are broken functionality, model-specific compatibility, and refund hurdles.
