Horrible. It continually spams me -- adding "friends" I don't even know to my page without my permission. 30-40 a day sometimes! Contacted FitOn repeatedly over several weeks and they couldn take to fix it. Very annoying and somewhat scary for anyone who values privacy at all. What else is hidden among all those friends that somehow get access to my account? Viruses? Malware? Deleted the app. It's not worth the worry and the aggravation.
