Oxygen Level Tracker : Pulse is an Android app that tracks blood oxygen (SpO2) levels. After completing the measurement with your side, add your SpO2 levels in the app for a percentage display on screen. The app also offers a chart to track changes in oxygen saturation levels over time. In addition, the app tracks your heart rate in BPM along with SpO2 levels. Note:- - Use the Oxygen Level Tracker : Pulse for track records, not for medical oxygen level checks. - This app is not for emergencies; consult your doctor. - The Oxygen Level Tracker : Pulse App does not measure Oxygen Level.
