Yes it would be worthwhile for anyone planning on supporting the big 3 "smart" watches to check this product out and the apps for. Simply to see what is popular, what works, what doesn't, and so on.

I do not expect them to have the big numbers of the others, but there should be room for entry level "smart" watch makers. the prices bandied about by Apple and others are simply appalling for a device which is slaved to another for some functions, at these prices it should be a phone on its own
