Hi,
Just that I suppose.
DP has one and uses it for everything! They're constantly monitoring heart rate, blood oxygen levels, sleep pattern in great detail, inputting calories, counting steps and now it's linked up to Alexa, so is constantly asking it to set alarms, reminders and timers!
Having said that, they do feel better and are getting fitter, so 🤷♀️
Do you have one? If so, for how long and do you still use it as much/at all?
I've been thinking about getting one, given DPs success, but am worried it'll turn into an obsession. I don't want to start panicking if my oxygen levels drop by a point or my quality of sleep was marked as only "fair" one night 
TIA
