PPG also known as Photoplethysmography is an optical non-invasive method for measuring the blood volume changes per pulse. It effectively represents the mechanical activity of the heart.
RPPG or remote Photoplethysmography is a method by which a face reader can measure heart rate and heart rate variability remotely. Where PPG is mostly used with wearable devices, RPPG detects the heart rate by using light and a completely contactless method. It measures the variance of red, green, and blue light reflection changes from the skin, as the contrast between specular reflection and diffused reflection.
No, our algorithms adjust for makeup on the face.
We’ve done many tests with a number of different skin tones.
Yes, it works on any iPhone 5 and above. It also works on most Android devices with a hi-res camera.
Yes, there is an iPad version also available.
As often as you like, we would recommend once a day, but depends on what you want to assess. The more vitals we can accumulate, the more predictions we can make.
No, our solution needs an internet connection as all the ‘heavy work’ of processing is done in our cloud servers from anywhere in the world. We need a decent 4G or good WiFi connection in order to get good accuracy.
