App Store (iOS) is the official Apple online application distribution system for iPad, iPhone, and iPod Touch.

An iOS device runs multiple apps simultaneously but only one has the user’s attention at any given time.  iCloud allows you to share the user’s data among multiple instances of your app.

Android powers millions of phones, tablets, and other devices and brings the power of Google and the web onto mobile.

With an amazingly fast browser, cloud sync, multi-tasking, easy ways to connect & share and the latest Google apps (and thousands of other apps available on Android Market) your Android powered device is beyond smart.
