Those include potentially life-saving ECG technology and all-day body response tracking for more accurate stress monitoring, which make this a pretty mind-blowing value proposition when you also consider the 24/7 heart rate monitoring, blood oxygen sensor, standalone GPS connectivity, sleep tracking, and up to 50-meter water resistance.
Compatible with both iPhones and Android handsets, the Sense 2 also comes with a six-month Fitbit Premium membership included in its standard (and its discounted) price, allowing you to gain even more insight into the way your body responds to your daily exercise and how you can improve your health and wellness without unnecessarily exhausting yourself.
