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.

User Reviews

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.

Pros

Cons

App does not work as advertised / provides no measurements or data
Inconsistent/incorrect compatibility with Apple Watch models; often restricted to Series 6 or fails on other models
Refunds are difficult or not available; users report trouble getting refunds
Data presentation issues: readings not shown, no data, or unreadable graphs
Pricing concerns: unclear or recurring monthly charge (e.g., $1.99) and unclear refund policy

Recent reviews

Not sure why Apple allows this in their App Store. Does not work as advertised on the iPhone or Apple Watch.

Hello developer(s) I hope you are doing well. Can you please do an update for downloading .pdf and others so that I can show my doctors how bad my levels are. I know that they won’t accept it, but I’ll be able to cram my levels into my thick medical records. Please, please. Thank you so much in advance. Have a wonderful day. Ps. I love the widget!!!
