A type to those who are considering buying a fitness tracker but don't want to look dorky with a rubber wristband:
I have a FitBit One (it is just a little "pod" with a rubber attachment thing that you are supposed to attach to your waistband, and it comes with a wristband that you can wear at night to track your sleep cycle.
I got the One for a few reasons, but the main one being that I looked like a serious dork wearing a wristband at work in a professional environment. Plus, I type on my computer all day long and already remove my watch and bracelets to more comfortably and quickly type, so I knew a wrist-type tracker was not for me.
I don't wear the One on my waistband either...I'm always nervous about it popping off my belt. Instead, I wear it clipped to my bra! I clip it to the center of my bra, in between my boobs, and it tracks my steps throughout the day. As a plus, no one knows I'm wearing it!
