From Michael West:
CheckWord is an iPhone/iPod Touch application that checks if a word is good or bad in games like Scrabble. Quicker than using a dictionary, easier than using a computer.Ã‚ Ideal for for both casual and tournament use.
This update gives you the much requested feature of word generation. Just enter in the letters from your rack and some letters to fit them to, and you'll instantly get a list of all the possible words you can make.
