Carat, new app for iOS Free, iTunes and Android Free, Google Play, has been designed to give users a personalized set of recommendations on their app usage to help extend their battery life. Developed by a team of UC Berkeley researchers, the free app collects data in the background and requires a few days of collection before it can offer recommendations. The anonymous crowd sourced data is sent back to UC Berkeley servers where complex algorithms are applied and a userís results compared with others before the recommendations are offered.
