>They do nothing your phone can't. Huh? The simple fitness tracker watches track your heart rate, sleep quality, step count, etc. Your phone can't do any of that stuff; you need something attached to your body for those measurements. >So far, the closest to a "killer" application for the tech is trying to gamify everyday activities by tracking steps, sleep patterns, or heart rate. So you just contradicted your earlier statement. >As for the fashion part... My cheap Amazfit fitness tracker is not fashionable at all: it's very boring looking, and no new band is going to change that. For some people, overpriced watches might be a fashion symbol, but for others (esp. anyone spending less than $75) they're really not.
