“The Basis Health Tracker smartwatch/fitness tracker hybrid is the first to make use of skin contact and an optical sensor to collect heart rate and perspiration data (although the heart rate sensor will not work properly while you’re exercising). Those sensors don’t come free, mind you—at $200, it’s about twice as expensive as many of its competitors—but if you are looking to collect the maximum amount of data from your tracker, no one will give you more than the Basis.” • #aqsc ∙ #no_wear - × × ×
