What is Pulse Oximeter app for iPhone and how does it measure your heart rate?

The Pulse Oximeter is an iPhone app from digiDoc which measures both heart rate and the oxygen saturation with the help of the phone’s camera to detect the user’s pulse and oxygen levels from their fingertip. It does so by combining the heart rate with blood oxygen saturation. The app comes integrated with Apple Health and does not require some external equipment or device to perform its function. You simply need to have an iPhone.

How does Oximeter app work?

Similar to other heart rate applications, the Pulse Oximeter requires a user to place a finger on the phone camera lens and wait for a couple of few seconds as the app takes the measurements. The app also involves an additional calibration process at the start which switches the LED flash on the phone to adjust Pulse Oximeter before a user places their finger on the device.

Once a user has placed their finger on the camera lens, it takes them through the calibration and measurement following a bunch of on-screen prompts to make it easier to use. After a minute or so, the app notifies the user that the monitoring has been completed before displaying the heart rate and SpO2 measurement.
