Like anagrams? Then you should try Whirly Words, lots of anagrams, pretty color changeable backgrounds, and soft music.
How it works:
You get your letters, a list of words (hidden) that you can make with those letters, and with each word you find your meter fills. You can choose to keep going till you find all of the words or find enough words to get to the marker in the meter and go on to the next level.
Whirly Word has over 5,000 puzzles, and you can shut off the in-game background music if you want to listen to your own music. I find Whirly Word a good way to get in some brain exercises through out the day. 
Whirly Word is available on the iTunes app store for only 99cents!
