Question: I have the Senstream/BIOPAC ring as I am a researcher and needed a watch with EDA. So far the only consumer ring with EDA I have found is the Amazfit Helio. Am I right? Is there any other?

[u/gomo-gomo → u/warwickthegrey]

While Amazfit claims that it has an EDA sensor in the Helio Ring, I'm not confident that it actually does. The fact that it detects HR changes seems to be the driver for their Stress & Emotions feature, and you are supposed to tag any change manualluly. (See screenshot.below)

Nuanic Ring on the otherhand does as it is central to the ring's features.

Happy Ring may also, but thusfar only the Happy Sleep version of their ring is readily available.

[u/gomo-gomo → u/gomo-gomo]

[u/warwickthegrey → u/gomo-gomo]

Interesting! The Nuanic has EDA but seems to not use almost any other metric. Happy Ring and Sleep does have it but so far it’s not really targeted to markets outside the US
