The Pulse Oximeter is an easy-to-use app that can measure your pulse and oxygen saturation in the blood. It is useful for people who want to keep track of their fitness levels and health.

This app can be used with any device that has a built-in sensor, such as Samsung Galaxy Note 4/Edge and Galaxy S6.

If you have a built-in sensor, you will need to turn on Auto-Stop and Auto-Start before you use this app. You can set Auto-Stop to 2 minutes.

You will need to wait for a few seconds after you start the testing, and you will need to stop the app and hold your breath for 30 seconds before you start the next test.
