Samsung and Fitbit heart rate sensors inaccurate on darker skinned people

The performance of wearables is of paramount importance as it is way more than just a fancy accessory. It is a fitness device which you expect to output accurate results uniformly across all races. Monitoring your heart rate is one such measurement that has the potential to save lives. A recent report by Stat alleges that some of the world’s most popular wearables from brands such as Fitbit, Samsung and others do not accurately measure the heart rates of people of colour. This is due to its reliance on green lights that are easily absorbed by darker skin tones.
