I can't get the FitBit app to monitor the steps that I'm taking on the treadmill without forcing a sync every time I want to know the total. I'm wearing the FitBit Zip and using the app with VoiceOver on my iPhone 5. I listened to David Woodbridge's podcast about the FitBit Flex, which I realize is a different model. But as he walked on the treadmill, he could count the steps just by flicking to the right and then back again. Perhaps, this isn't possible with the Zip using VoiceOver. Can anyone shed some light on this for me? I would certainly appreciate it.
