Whatever you decide, focus only on what it can do for sleep. Its activity tracking is not good. Meaning, of course if it tell you that today you walked 10K steps and yesterday 5K steps, then yes, today you walked more. But in absolute terms, it seems to overestimate what you actually worked. And it is not sensitive enough. I know people who swear by Oura ring for sleep tracking but they have Apple watches to track their activity. They do not use Oura for daytime activity tracking, HR etc.

I am surprised this is so. It seems that tracking from the finger would be at least as good as tracking from the wrist. So I do not know why this is the case
