I have the Oura ring. Overall I’m reasonably happy with it, however it does have some limitations:
- As far as I can tell, it does nothing during the day. It doesn’t track HR during the day, and doesn’t do any activity tracking during the day as far as I can tell.
- They want you to enter your activity manually so they can track it, but I haven’t bothered. This leads to weird ‘activity balance’ warnings. It still tries to analyze my activity, but it has no activity data so this causes some confusing messages. I’d like to see an option where they take activity out of it completely, and just report recovery/readiness information based on what the device can measure. I’d happily take shorter battery life to have it measure useful stuff during the day.
As far as sleep, HR, and HRV tracking go it seems to do a good job. I think its sleep tracking correlates better with how I think I have slept than my fitbit, although I haven’t done any close comparisons. The resting HR and HRV are highly correlated as I expect, but it’s hard to know how accurate these really are.
My main goal of using this is to get HR/HRV data that I can use directly, and it gives me that. Their ‘readiness’ score seems mostly based on how you slept the prior night, and only slightly influenced by the HR/HRV, so I don’t put much stock in that, other than looking more closely at my numbers on those days.
I went with the Oura (on sale for Mother’s day as it was much cheaper than the Whoop. I can’t get behind a $30/month subscription for this. My ring was $335 out the door, so cost was a big factor for me. From reading the details on Whoop it seems like even though it is a subscription, it is still structured as a HW purchase, so if it breaks you could have to ‘buy’ another one. Also no clear information on what access to the new hardware my subscription gave me. If I’m paying a subscription for HW, that needs to include guaranteed working, up-to-date hardware. The hardware is interesting, but their business model is not.
