Skinner's Typewriter is the perfect word editor for the writer with writer's block who needs a push to get rolling again. It is an iPad application that functions as word-processor. You first enter how many words you want to type and how fast you want to type them. Then if you fall behind your intended speed, Skinner's Typewriter punishes you with various levels of punishment (from reminding you to type to unpleasant noises to starting to delete your text) until you start typing faster. It's perfect for forcing yourself through rough drafts and getting ideas down quickly, and since it is on the iPad, it is very mobile.
