How to check Oxygen level without Oximeter?

Pulse oximeters typically use an infrared light source on one side and a sensor on the other to detect an oxygen saturation; a smartphone just uses white light (i.e. in the visible spectrum).

The app uses “reflective pulse oximetry,” which allows the light source and sensor (the camera in this case) to be next to each other.

And according to the paper, the app measures oxygen saturation “within 90–100% (version 2.0.4) with an accuracy of 0–4 RSM compared to a medical-grade pulse oximeter.” There is however no publicly available or published data supporting even that claim.

The app does include the usual disclaimer: “This app is for entertainment purposes only. The measured result can only be used for your reference. Consult a doctor if you have any health concerns.”
