 FitBit    
FitBit 制造的設備 FitBit Ultra 可以幫助測量你一天中走了多少步，爬了多少樓梯。它可以追蹤你的跑步情況，消耗了多少卡路里，它同時也可以追蹤你的睡眠情況。

Fitbit is dedicated to helping people lead healthier, more active lives. We take a common sense approach to fitness, and believe that the key is to make it easier for consumers to be more active, eat smarter, and get enough sleep — in short, that small changes to your daily routine can add up to big results. To that end, we aim to create innovative, inspiring products and online services that harness the power of new technologies to make people more aware of their everyday activities and motivate them to do more.
