No, all it did was show you wealthy areas where people buy stupid crap.
These are really stupid devices. I have the thermometer in my hand when I take the reading, I can just glance at it to see the reading, why do I need it to sync to my phone?
I also really like your point about the data being skewed because of the price!
For persons with an uterus, reading a thermometer can be used both for getting pregnant (=have sex on the day where a slight increase in vaginal temperature indicates that an egg is released) and for preventing pregnancies... and the latter case is where the phone sync comes in handy. The pregnancy-prevention apps work by profiling the dates and volumes of periods, plus sex drive, plus temperature, to determine a window in which unprotected sex is risky (IIRC, it's seven days prior to egg cell release + 1 or 2 days after).
"Log in with facebook to see your temperature"
I wonder if there's a "share temperature on Facebook" button in the app?
