I keep waffling on what fitness device I am using. After lots of replacement units of the Jawbone UP I got a Fitbit Flex in September. I used both devices for most of October to see how they compared. Then I dropped the UP in favor of the Flex. Part of the reason I did that was that the UP was too big on my wrist after my weight loss in recent months. The Flex didn’t have the inactivity monitor that I liked with the UP. it also seems to record about 2,000 more steps a day for me than the up does.
Just as I was getting used to using the Flex Jawbone comes out with the UP24. It offered me the bluetooth sync that the Flex has and all the features that the original UP had. I took the risk and ordered one in Medium hoping it fits and i can go back to using the UP. I will write more once I get it and see how it works.
