Can I Use My Phone Camera to Track HRV?

We have released "Research Readings" to a portion of our app user base. Our goal is to learn if measuring HRV by placing your finger over the smartphone camera (also known as finger-over-the-camera) is an accurate and viable alternative to chest straps. 

If finger-over-the-camera proves accurate, we'll be able to offer this method to our community, as a convenient, accurate alternative to chest straps. 

For the time being, you will not be able to take your HRV with only a mobile device (like a phone or tablet); you also need a compatible heart rate monitor: Compatible Devices
