I like FitBit devices and app.
So far, we got the FitBit for the family, and our kids love the FitBit Aria, the intelligent weighing scale that sync wirelessly, and then sync into the smartphone FitBit app.
Have used the FitBit Force for running, walking, cycling and not yet on swimming. Probably will do that when I can find a place to swim.
The Force works really well and in fact quite accurate, if I compares it with the Flex. Or maybe because it has the on screen display, which I can see the step counters from time to time.
The battery lasted for about 4-5 days before I charge it.
The charging is different from the Flex, which comes with an adapter. The wireless dongle which comes with the Force is the same for the Flex. So I just carry on with the dongle, instead of having too many of them around.
For the charging, it is fast, so just the same as Flex.
The additional tracking in Force which Flex does not have – the stairs climbing. I am planning to take it on a hike with the kids this weekend to check on the tracking.
For the alarm, the vibration works really well, in fact much stronger than the Flex.
What I dislike, the Force is a bit too large.
Other than that, will share more.
