## Description

**Blood Oxygen SpO₂ Tracker** helps you review existing blood oxygen readings from Apple Health on iPhone and Apple Watch. See the latest available value, daily history, 7-day averages, minimums, maximums, outliers, value distribution, and optional barometric pressure and altitude context.

Add iPhone widgets and Apple Watch complications for convenient access, or enable optional notifications for readings below a chosen threshold. The app is read-only, does not measure SpO₂, and is intended for general wellness—not medical diagnosis or treatment. Some features require Premium via subscription or a one-time lifetime purchase.

## Review summary

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.

### Cons

- 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
