A dedicated app for Google Analytics is now live on the Appstore. The app has a good free version that gives you all that you will require for a quick look. The app is supported by Ads however the same is eliminated in the Paid version. This is a good tool for active webmasters who use google analytics. But you need to have a google account to access this app.
Webmasters are power users and a lot of them would be using good smartphones. Such an app makes a lot of sense.
Competition: MyAnalytics (AppStore $3.99)
