Cleaning out my place and found and old zeo sleep tracker. It’s the headband one that you connected with a phone app. Not sure if you can even get the app anymore.
If anyone is interested & willing to pay the shipping, just let me know & I can send it over. Just PM me.
I sent Adrian a pm maybe 20min after he made the post, haha
Excited about using the Zeo in some experiments (currently doing a standard ABA with magnesium) and having more sleep data, and will definitely share the results!
