From the developer:
SpellBoard allows you to practice spelling words in any language. Whether you are a student, teacher, or parent, we all know the weekly spelling drill. Monday, we get our weekly words. Wednesday, we have our pre-quiz and Friday is the spelling test. Of course, during the week there are endless impromptu spelling quizzes -- at home, in the car, at dinner, before bed -- you get the idea.
