Still waiting on app review so here is another sneek.

You get a full detail view of the information from Ravelry with links to the suggested yarn and the hook information etc. you can favorite, add to library or start a project from here.

Also the yarn weight information is linked to a view showing the yarn weight in different international systems. So what does Bulky mean in the German yarn system for example.
And of course you can switch between meters and yards to your preferred unit.
