I have an old Samsung Gear S2 watch and was looking for a way to get smartthings control on it. Samsung does not have an app in the Galaxy Wear store for the S2, so I found a browser and created a link to actiltiles.
For those that may be interested, the Browser app is called WebBrowser. You need to go to the panel you wish to access on a regular web browser and copy the link and re-type it all into the watch browser (pain I know) then set it as the homepage.
