Mobile Device Reporting: know which mobile platforms work best
Discover which devices visitors are using to find your website so that you can present your brand in the best formats for those devices. Google Analytics can display which mobile operating systems and specific mobile devices send visitors to your site, mobile app or social media page.
See where mobile traffic comes from
Viewing statistics by location (Map Overlay tab) lets you understand the current origins of mobile traffic, as well as make predictions about where traffic will increase.
Measure mobile app performance
Measure usage of your app as if it were a website. The Google Analytics Mobile Apps SDKs make it easy to measure success of your mobile apps. You can download the SDKs for both the Android and iOS application platforms. For Android, you can measure from click to the Android Market to a download. It's a simple way to understand which campaigns work.
