Only if we can get that data exported in a format that can be used by the next 'standard'. I've already got health data on my Android phone, a Fitbit account, my Withings devices, my old iPhone, and probably more elsewhere.

You can export all the data from Apple Health from a button in the app. It exports a zip with data in a usable XML format. The Health data is also available via an iOS API so there are apps available which pull and export the data in other formats (e.g. CSV). I try to connect any health related apps to Apple Health (e.g. Withings, MyFitnessPal) and use that are the central repository.

I would love to try it but I'm guessing it won't work if I just buy a cheap used one and never attach it to an account and never bring it online?

Not sure what you mean by "one" but a watch will work fine without a network connection. It does need to be paired to a phone.

It'd make it less useful as a watch though because the time will drift without an NTP server.

		I don't think this is true? All my Apple Watches refuse to provide any functionality at all, including just telling the time, until I pair them with an iPhone. This was an issue when I bought my first Apple Watch because I owned an Android.

On android I'm able to extract some of this data by directly accessing the sqlite files in the databases directory of my rooted device, (with sudo-level permission obviously). I find that much more comfortable than having to use APIs with temporary tokens

Opposite direction, but I was able to export most of my activity like sleep and daily steps from Fitbit to Apple Health (using a 3rd party app unfortunately.)
