I would assume that to achieve a 7 day battery life they only take rare measurements of your heart rate, which makes it unfit for the kind of high resolution heart rate tracking people are used to from fitness watches. They also mention that any sport which has a significant level of hand involvement might disturb the reading.
They do still track general intensity of activity though, which for general health is probably a more relevant metric than exact heart rate.
- underyx 6y agoIndeed, the automatic HR measurement powers the heart rate sensor array only when the accelerometer reports that the ring is stationary, i.e. the user is likely sleeping. This also makes sense because hand movements tank the accuracy of the sensors anyway. With manual measurements, you can still only get useful data if you're using it to measure during meditation or rest.

- jerlam 6y agoThe Oura only measures heart rate in five-minute intervals [1] while sleeping. A workout set/running interval could easily be completed within five minutes, making the measurement useless. I've had many instances where my Oura failed to track heart rate while I was asleep, if the ring rotates, slides to a thinner part of my finger, or I am moving a little too much.
