Many of the note-taking apps for the iPad feel busy or are full of distracting features, but HelvetiNote is a simple minimalist option. It lets you hide everything and just focus on your writing.
The app will set you back three bucks and is available in the iTunes store. [iTunes via TUAW]

And sorry to be so nit-picky, but I find it difficult to use the word "writing" in regards to an iPad.
