The wearables market is trying to find it's sustainable model at the moment and we are at the low point of the hype cycle. Part of the issue has to do with the business model with hardware devices like this. IE: A one time hardware purchase that needs to fund all further software updates etc. and the reliance on continually selling new hardware to stay in business.
Then there was the issue of needing to learn another dev stack to write applications with it vs the Apple or Google offerings that leverage Android and IOS development skills. Right now the largest market in the space is with simple devices such as fitness trackers. The disappointing thing is that Fitbit isn't as open with their bluetooth stack/Gatt profiles, but that's another discussion.
