Independent Validation of HRV4Training

There's a new independent validation out looking at the accuracy of commercially available HRV apps and sensors

Great to see the results for the lowest median error:

• HRV4Training + H10 (3%)
• Oura ring (4%)
• HRV4Training PPG (5%)

This is confirmation of the quality of the work we have been doing for the past 8 years, starting with early analysis of the accuracy, then our validation paper, and finally with this independently run study confirming the accuracy of the methods we have developed for both the camera based acquisition and artifact removal for RR intervals acquired from external sensors
