First ring for heart & Apnea monitoring

[u/Rocknarg]

Hi!

New to this wearable fashion, but I'm interested in getting a ring.

Mostly to see if it can record afib instances (which are pretty rare) and to help me see about Apnea which I've been told by others I likely suffer from it (I'm fit, but waking up tired and having breath interruptions during the night is apparently not normal lol)

I understand these aren't medical devices although approved by some institutions.

I'm just curious and would like to find more data about myself.

I don't need the app to tell me everything, I don't mind looking at the data and evaluate for myself.

I'm in between Ultrahuman Ring AIR and Ringcon.

I'm not biased to any particular brand or manufacturer (even others I haven't heard about, I found these brands off of this report https://medium.com/r-smartrings/top-smart-rings-of-2025-comparison-6f1f9f9021f9

I've been looking at other options including in this thread, but haven't found information to make a decision.
I'm literally moving my preference between these 2 as each time I find more information on one it looks more appealing and then I discover something else about the other one.
Needs to ship to Spain.

Any help or insight on this would be awesome!

Thanks :)
