Using WordPod is an intuitive way to read books on your iPod. It converts plain text e-books into a format that iPods can understand, and copies them to your iPod. Navigate by chapter or by page number, using the standard iPod interface. It even generates books that work without WordPod installed, so you can share them with friends, or publish your own iPod novel.
In addition to all the definitions from Merriam-Webster's Collegiate Dictionary, this app offers voice search - to let you look up a word without having to spell it - along with synonyms, antonyms, example sentences, Word of the Day, and more.
