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 =)

Not what you're asking but on the opposite side you might want to check out gadgetbridge.

Gadgetbridge is a free and open source Android application that allows you to pair and manage various gadgets such as smart watches, bands, headphones, and more without the need for the vendor application. So in short, you can use Gadgetbridge instead of relying on your gadget's own proprietary app.

Thank you, this is an amazing project. I found something interesting in the source (I found the fresh squeezed juice meow.) =)
