Author here: That video is an in-house demo of an early prototype on a Samsung Galaxy Gear, so yes it works on those! Minuum isn't yet shipping on any smart watches, but we're hoping to have something out as soon as possible.
We will be setting up an alpha with some Galaxy Gear users in the next week. Some technical know how will be required, but if you're interested send us an e-mail at developers@minuum.com.
