Frequently Asked Questions

Clearly we get asked a lot of questions about our technology and how it works. We’ve tried to answer the most commonly asked questions here, but if you have a specific question, please feel free to ask us.

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.

Please refer to the following article which explains the process by which vital stats can be read using RPPG.https://www.noldus.com/blog/what-is-rppg

No, our algorithms adjust for makeup on the face.

We need normal lighting conditions for an effective reading, bright sunlight or glare affects the readings and are not recommended.

We’ve done many tests with a number of different skin tones.

No, our technology is agnostic to age.
Our readings depend on the speed of your internet connection, but on average take less than 60 seconds to perform.
We take your snap shots for processing in our secure Azure cloud, once we have extracted the vitals , all information is deleted and the only data we keep is the core vitals, time stamped with no personally identifiable information.
We are not a device, we offer a software based solution which offers a first line of defence to detect vitals based on rPPG technology. This technology does not replace a physical device which would be used in a hospital or by a medical professional. We have started the journey of regulatory approval.
Our accuracy is at 95% against a regulated device. We have tested it against high grade OxyMeter.

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.

Not yet, but it’s in the pipeline. Our demand is mostly for mobile phones which people have with them all the time, hence the convenience of using our technology on the go.

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.

We’ve tested our technology on a variety of ethnicities including darker skins.

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.

We offer a SDK and integration options, please speak to us on how this can be integrated into your application.
Our system is easy to integrate and we provide full documentation and support for the integration process which is relatively simple. Please contact us for further information on how to integrate.
We process the data in Microsoft Secure cloud servers based in Azure, and once your data is processed, we delete any PII information. Please refer to our privacy policy for further details.
No, we are not a replacement for any healthcare professional. You must seek your healthcare professional for any medical advice.
No we cannot, this has to be determined by your health care professional.
No, but we are planning to file in the near future.
