Not really free, but worth $0.99!

A few applications have been hogging up storage on my 16GB iPad (ex. Magic Piano, Magic Jigsaw). So I downloaded this app. After running it once or twice for free, it prompts you to buy it for $.099 - a little tricky in my book! Since the initial runs did find some junk, I bought it. It has since cleaned my cache and found over 1.5GB of storage for me. It especially reduced the storage of Magic Piano and Magic Jigsaw!!
