I'm looking for a cheap (~40$) smart ring (programming.dev)

Good morning 👾

I'd like to fetch data via BLE (Python or Swift) from a cheap smart ring that can be reverse engineered or that is already RE'd. Pulse, oxygen levels, gyroscope, button would be very useful. I'd like to build a python or swift library.

Thank you for any input =)

Didn't pebble release a smart ring? I don't know the price, but from what I understand their newer stuff (since the relaunch) is either fully or mostly open source.

I don't know if it includes the sensors you want though.
