I'm so excited to play with this. I just ordered one. I've gone through two Oura rings (I do not reccomend). I'm not sure this will be reliable but it cost me $14.00 not $300 and doesn't charge me monthly to access a mediocre api.

Im eagerly awaiting a ring sleep tracker like it which can be used offline with gadgetbridge or something.
Accurate tracking of what? And which smart watches?
The Apple Watch seems to generally have the most accurate tracking according to most studies, which surprises me.
When I was looking at buying an Oura and browsing user subreddits, it was full of complaints about inaccurate readings and the slow intervals between readings.
Your Oura ring will likely get bricked by their updates (they'll replace it, but come on). Or you could simply have a busy week, forget to charge it and ban. Bricked.
They of course were first to market with this form factor, so they of course are going to be the ones to take most of the flack for all the growing pains that come with that. This is typical with any new platform. However, they still leave a ton to be desired and I can't really see how they'll survive the next few years with all the competition in the space.
