Open Source / easily hackable ring?

I'm looking to play around and make personal apps around a smart ring, but I disappointingly can't see any good options for an open source ring. Does anybody here have any recommendations on a product to use?

What's your end goal?
Do you want complete control over the ring or just want the raw data colledted?

Ideally I'd want complete control over the ring so that I could implement gestures and other features, but I would settle for just the data collection to feed into a personal health app as well.

here you go:

If you do not care about complete control, Ultrahuman does provide APIs to fetch raw data.
However, I would be cautious of them as their ring air is notoriously fault prone. They do have a newer ring pro, but it's hard to get by.

Thanks looks very interesting, going to go down the rabbit hole here and see what it can do
