"Of all the brands of fitness trackers on the market, Fitbit takes the trophy for being the most well known, and for good reason. The company has been iterating and spinning out different versions of its original Fitbit Ultra smart pedometer since 2011 (2008 if you start counting since the initial public concept reveal). Its latest and most advanced fitness tracker to date, the Fitbit Surge ($249.95), is a rather sophisticated piece of machinery in the form of a touch-screen wristwatch. It not only tracks your steps and sleep, but also alerts you to incoming phone calls and text messages, keeps tabs on your heart rate with a built-in optical heart rate monitor, uses GPS to track outdoor activity, and has much more functionality especially for runners."
