Two of my favourite and most used IOS Apps - Drafts and OmniFocus - are able to be used together in a number of ways that aid speed entry of tasks and collection of your 'stuff'. Remember stuff? That's right, those loose threads in your mind that don't actually belong there. OmniFocus works as a great collection tool for these items and I use Drafts for almost all of my information gathering due to the URL schemes it is able to use withnother apps.
The developer of Drafts, Greg Pierce, has written a great article on how to make the most of the relationship between these apps and you can find it here
