Pulse Oximeter: Oxygen Tracker is an Android app developed by dreamApps. It falls under the Lifestyle category and specifically the Health & Fitness subcategory. This free app allows users to monitor their pulse and blood oxygen levels using a pulse oximeter. With Pulse Oximeter: Oxygen Tracker, users can record their measurements and compare the numbers over time, providing valuable insights into their health status. The app also offers features like browsing records, viewing measured data, and examining oximeter statistics charts. It even includes zones of heart rate and the proportion of oxygen in the recorded data. It's important to note that while the app saves oxygen and pulse rate information, it does not actively monitor these readings. The data and graphs provided are solely for identical oximeter readings.
