Measuring heart rate isn’t easy. It’s why doctors and researchers try to get as close to your arteries as possible to get the most accurate and unfiltered reading.

While other “wristables” tend to measure from the top of your wrist (further away from arteries) Oura measures your signals from your fingers (right next to your arteries) where it can get the most accurate read.
