I co-founded and ran Pinch Media, which recently (transaction announced last week and closed yesterday) merged with Flurry. Now I'm doing product management there. I'm assuming you've written a native app vs. a web app. (If not, my apologies - ignore any advice I give you.) While I'm ridiculously biased, I'd recommend going with Flurry Analytics. In a couple months, it'll have the superset of features from both Pinch and Flurry. The data is processed using Hadoop, and reporting updates very quickly. It's built for multiple platforms, so it'll stay with you if you decide to build for multiple phones. And the company's well-backed and doing well financially - which is an important thing to consider, because once you release a smartphone application with analytics code in it, at least some installs are out there forever, since you can't force 100% of your users to upgrade. Of course, because I'm ridiculously biased, you probably should check out other solutions in the space as well. :)
