About Word Aid
This is a GREAT app that will help you solve for almost any word in 'Four Pics One Word' and give you plenty of ideas for other word games such as 'Scrabble.'
The app allows users to input the number of letters in the word and the letters available to spell the word, and when the "Get Words" button is clicked the app searches through a list of over 45,000 words to find all that fit the criteria (length and available letters) provided by the user.
