Can confirm. I have several wearables lying around no longer being used. The difference between the fitness devices that I use (smart scales, gps trackers) and the ones that I don't (pedometer/heart rate wearables) basically seems to be that the ones I use are measuring and recording data I was previously interested in before getting a device that tracked it. Ultimately, I can't get excited about a pedometer because I simply don't care about how many steps I take.

Also, the fact that the pedometers require near constant use to be worthwhile means that there's some degree of mental energy devoted to them - is it charged, am I wearing it, etc. A smart scale I step onto for a few seconds each day and my garmin head unit is only used when I'm riding my bike so there's almost no conscious overhead.
