The official Google Analytics iPhone and Google Analytics Android mobile applications have been released so you can access all of your Google Analytics web and app data from your iPhone. The app even includes Real Time reports.
The app optimizes the Google Analytics report layouts and controls for a mobile environment, so you get the best experience no matter what device you use. For example, the app automatically adjusts the display to fit your screen size, and the navigation is based on touching and swiping instead of traditional keyboard typing.
Here are some screenshots:
The only limitation to the Apps are account configuration and settings, like creating properties or views, editing Goals or filters, adding users, and changing permissions. Those features require that you sign in to your Google Analytics Account using a desktop browser.
