Older M, Oura 3 user since the pre-sale (2 or 3 years). Haven't looked yet at the 4 but suspect I will get it. Two reasons. First- the best way to understand it, for technical folks who, say, operate software services- your main source of telemetry about yourself- more specifically, your cognitive operating capacity- is what's called interoception. This includes some more or less binary measures that your brain LLM has developed/evolved over time, as well as a bunch of qualitative factors that are themselves often an unreliable indicator of the "load" your "system" may be facing (from infection, injury, overeating, alcohol, stress, whatever). How do you "feel"? Eh, that's not reliable. The Oura is a good enough quantitative sensor that conveys a number of metrics that are extremely useful in understanding factors impacting the "performance" of your "system." Overnight heart rate, temperature, HRV, actual sleep stages and sequences and times- it isn't obvious to someone if they haven't received this data, but once you start receiving it, it is tremendously useful, both because it is explanatory and because it is actionable. Life is a continual maintenance process and in the absence of that telemetry, you're going to be less responsive to certain categories of challenges your person is exposed to. The Oura has often picked up on or provided a heads up that my person was under load in ways I was not consciously aware of, and that has been helpful in allowing me to plan to, like, take a nap, to improve recovery, or pick up my exercise routine. When you don't have this data, you just don't know what you're missing. The second reason is that the Oura business continues to work to deepen the metrics and the distillations in ways that initially don't seem (to me) to be immediately valuable- a newish metric called "resilience" is an example of this- but then as I follow the telemetry over time my mental model evolves to understand and identify what actual aspect of my interoceptive experience that metric attempts to quantify. This work is insightful, almost art, and takes judgement, and I have been impressed by the Oura team's decisions here. So I am happy to continue to give them my money- it is far more useful of a subscription than, like, $15/mo for Spotify. I will probably get the 4- I assume that it will be a more sensitive instrument. Right now the 3 has some instrumentation flaws and limitations. It sometimes misses naps or certain activities. It only samples temp and heartrate once a minute. There is a fair amount of modeling on top of the underlying dataset. I imagine the 4 will represent an advance in sensitivity, and therefore hopefully an improvement in the models reporting metrics. Hope that's helpful. Really is super useful as continual telemetry.
