iOS: Editing is often the toughest part of writing, but Voice Dream Writer is an iOS app that helps with the proofreading and organization part by offering up a variety of text-to-speech capabilities.
Voice Dream Writer has a set of proofreading tricks that can help you check your writing: text-to-speech reading, phonetic word search, and outlining. The text-to-speech simply reads your text back to you to help you find mistakes. It works surprisingly well and is a little more helpful than just reading it out loud to yourself. The phonetic word search is also really handy when you can't seem to figure out the word you're looking for. The outline is perhaps the most useful, especially if you're the type to move sections of text around. Voice Dream Writer's technically designed for people with reading disabilities, but it's useful for just about anyone who needs a little help proofing.
