Speller - Free Spell Checker This is a very basic spelling app that uses google to spell check. You type in the word, suggestions of the correct spelling come up, or you can press the google button, which will take you to the web definition. I assume there are more languages if there is a pro version, but for now it's all in English. This app is a great time saver!
