What are your favorite apps on the iPhone?

What are some good (=polished UI) apps built with Appcelerator Titanium Mobile for both Android AND iPhone?

• I'm currently evaluating Titanium and wondering how serious such framework can be taken to develop real high quality (especially UI wise) cross-platform apps. Looking at the Titanium showcases at http://www.appcelerator.com/showcase/applications-showcase/, you mostly see apps done for iPhone only, there are a few apps that are built for Android and iPhone, but they're pretty basic (don't go beyond common list views), and mostly when you look at these samples (i.e. the NY Senate app), the Android app looks so crappy compared to the iPhone version. Take the tabs widget for example, none of the Android apps there have customized  tab group (i.e. text captions not even fitting on the tab/screen) and most Android apps just leave it to the black standard theme -- which experienced developer with a sense for good UI design does that? Therefore my question: are there any apps out there that might not be on the Titanium showcase page, which are really cool and looking polished both on iPhone AND Android, which have been done with Titanium Appcelerator?
