A few days ago I downloaded a new app: Index Card by Denvog. It is a tool for writers to organize idea and story components on virtual index cards (just like the old days when you had to write a research paper for school) right on your IPad.
I started using it last night when an idea for a short story came upon me. I am still on a learning curve, but what I am finding useful to me at the moment is that I can storyboard ideas from the comfort of my reading chair with the tap of my thumbs rather than having to spread out cards on my desk or the floor.
When I complete my story, then I will give you a final assessment of the product. In the meantime, you can see how the apps works through this video review:
