I found this on appbrain’s developer tools site.

It will analyze your app and give you stats and tips about your market descriptions and your apps presence in the google market. Thought it was interesting if not helpful! One very interesting thing is it anaylze’s your description and shows the weight of your keywords based on search popularity. I’d like to know how it determines the weight of your keywords though. Could definitely use this as it’s show most of my apps have popular search keywords in the description but they are not weighted very high.
