Convert simple Tizen app to WearOS (Galaxy 4 watch)

I have a very simple timer app that was written to run on Tizen and was running on my Galaxy 2 watch. I now have the Galaxy 4 watch and would like the app ported across to be able to work on WearOS, so it can run on my new Galaxy 4 watch. I have all of the source files for the app. I expect this will be a very easy conversion.
