Fit bit are one of the first companies to offer a fitness tracking gadget and they have released several iterations.
They are now due to launch the Fitbit Force, which is the follow-up to the Flex and adds a couple of features missed out before. One feature is an altimeter that calculates your current altitude and the number of steps you have climbed over a 24-hour period. The second is that the Force will offer a digital watch face.
Apparently the Force will be priced at $129.95, $30 more than the Flex which seems a little steep for an addition of one feature left out, and a basic watch, however as the product has not been launched yet we will reserve judgement until then.
