Own a smart watch?

Does anyone here own one of those smart watches? I know there are various ones out there on the market for all types of users, phone-linked ones like Apple's one or the fitness tracker things like FitBit. They all seem to have there various usage. For me, I own an Apple Watch (as it came with my contract) and I just haven't used it as much as I probably could. I forget to charge it and then it's the last thing I think about doing in the morning, I generally need to get ready not look around for the watch and spend the time slapping it on my wrist. Not sure I'll get one of my own steam in the future anyway.
What about you? Do you own one? If so, what do you use it for?
