I downloaded this app after getting fed up with the other Analytics apps, and after a day or two of usage, I can say that Im really impressed. This is to me more useful than the real Google Analytics web interface. Its easier and it displays all the information in an organized and meaningful way. The only thing that worries me is the way it does authentication. It asked for my username and password the first time I launched it, and Im not sure how it stored this information, whether its on my phone or on their server or what. I hope its on my phone and encrypted.
