How are you really doing? is the question that the developer of One Aura, developed by Ryan Archdeacon, is trying to answer by designing an app that reports metabolism (body fat and carbs) and circulation (heart strength, endurance, life expectancy). According to Mashable, he is using “analytical computation, algorithms and data visualization to derive higher-level meaning of the data.” The outputs are certainly interesting, but the interpretation methodology seems to have missed both the article and website. How metabolism and circulation are arrived at from data inputs from simple heart monitors such as the Zephyr HxM, Polar H7 and others (not Fitbit or Jawbone)–one wonders. Less than what it seems?
