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.
I wasnt expecting the colmi to be accurate for this low price, but still.
For gadgetbridge I dont think there are any good sleep trackers and the only two I know of that are genuinely accurate are the apple watch and oura (theres a guy who tests them all on youtube - this is what he found).
Id happily pay extra for a decent non-apple local storage only fitness tracker which integrates with OSS and doesnt upload every heartbeat to the cloud but it does not seem to exist.
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.

While I still love the ring form factor. As tacky as it sounds, I still wear my bricked Oura rings sometimes just because I like the feel lol. However, I would never trust Oura ((or any other device outside of Apple(unfortunately)) to gauge you health off their data. While Oura is directionally correct (like most of them), it never once detected low oxygen levels in my sleep and I have some of the worst central sleep apnea my doctor has seen.

What bothers me about these sleep tracking devices is they are often "on the low" reccomended as ways to detect sleep problems like sleep apnea. This might not be done by the companies themselves but it is certainly done by influencers who are hired to promote these products. If someone were to buy an Oura ring because they snore (one of their marketing tactics) to try and see if they have sleep apnea there is a high chance that the app would tell them their oxygen levels are fine and then they'd never go get a sleep study (which cost less than an Oura ring with home kits now). Assuming this caused them to never follow up on that snoring again, Oura's (and other companies) marketing and mediocre tech would quite literally shaved years off this persons life.
When I asked my doc if sleep apnea could kill me if left untreated, he responded, "It WILL kill you if we leave it untreated."

Edit: I do believe in 5 years Oura and other similar products will have figures this out. Just not yet.
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.
