The new product is described as “an intelligent, wearable wristband with an application that combines tracking, analysis, social and motivational elements.” Jawbone, which makes a popular Bluetooth headset and also the Jambox wireless speaker, said Up will track a user’s movement, sleep patterns and nutrition. I love my Jambox. If Up is as good I can see this hurting the sales of Fitbit. My wife owns a Fitbit. She has difficulty in charging it and getting it to sync sometimes.
