After frustration with UP24 I gave up and changed to FitBit HR. It lasted maybe three months before I was sure Jawbone UP was incredibly more exciting to use. I bought an UP3 and I so love it! The app is now more useful than ever and I can really see a lot a patterns. For example, I could see I slept much better now that I am pregnant. I could see when I drank to little water during a day (reflected on my passive heart rate reading in the morning) and so much more. I love Jawbone UP because it DOES something with the data showing insights not just graphs and "completion" bars :)
