There's no better motivation than public humiliation, err, community support. Which is why Jawbone's extending its Up band's social circle to encompass the likes of Facebook. Previously, Up users could only share their dietary, exercise and sleep habits with other registered users, but now that feed will also extend to a user's Facebook Timeline. The company's also ushered in a few tweaks for its Sleep alarm, now offering the ability to set specific wakeup alerts or configure Smart Sleep timers for 30, 20 and 10 minute windows. The update's live in the App Store today. So, if you've been dying to share your physically fit and / or gluttonous ways with a much larger audience, well, now's your time to shine.
