Blood Oxygen Level: Your Simple Daily Health Tracker

Summary

This app receives largely negative feedback from users, primarily due to its inability to accurately measure pulse and oxygen levels, often providing fake or static readings, and failing to connect with smartwatches or other health devices for automatic data input. Many users also express frustration with hidden costs, deceptive subscription practices, and intrusive advertising that sometimes hinders functionality. While some appreciate its simple interface and usefulness for manual data logging, the overwhelming sentiment points to a lack of core functionality and transparency. A specific bug was noted where the app's UI conflicted with iPhone 12, preventing users from closing ads.
