We all know the big names in fitness and sleep trackers. Just about everywhere you look you can find someone wearing a Jawbone wristband or a FitBit tracker. Those trackers are on the pricier side of things, however, and not everyone is willing to spend that much on tech that might -- like their last gym membership -- end up going unused. Enter the budget tracker market where Xiaomi's Mi Band largely goes unchallenged. Late last year a company called Pivotal Living based out of Seattle, Washington introduced an even more budget-friendly option, at least for the short term: its Pivotal Tracker 1 wearable, which is free if you sign up for a year's membership at $12.
