I wrote my post an hour ago, immediately edited it 1 minute after to put the following in "on edit: note this is my idea of what smart rings should do, don't know what the normal ones do, so my idea that it should be a luxury item may not track actual situation"

you posted yours 44 minutes ago.

I hit add comment, went off to do the dishes while I thought about what I wanted to say and didn't refresh. Sorry!
