I owned a few of the Jawbone UP fitness trackers. One stopped working, so I ended up getting a replacement. A button fell off the other.
Jawbone Health Hub is a new digital health startup that is launching as Jawbone closes its doors. According to several sources, it sounds like a number of former Jawbone employees are following the CEO to this new startup. If they build a lean team and have access to the wealth of user-generated health data from Jawbone, then this startup could gain value very quickly. I was always impressed by the way that Jawbone nudged users with health tips, relevant articles, tips/suggestions, and tailored feedback.
Good luck to the new Jawbone Health Hub!
