iPad Usage

We’ve been surprised by how much tablets (i.e. iPads) are currently used with NASA’s internal mobile applications. 24% of users (1,396) have accessed a mobile application at least once with an iPad. 424 users access mobile applications with just an iPad. 189 users access mobile applications with an iPad and non-iOS phone (Android or Blackberry).
In May of 2012 we made a public announcement that an iPad version of a mobile application was now available. The following chart show the iOS visits and users by device model type since that time.
iPad usage
During this time users with iPads have accounted for 30% of the total activity. The takeaway from these numbers is that optimizing your application for tablet usage (particularly iPad) is extremely important. Tablets provide significantly more screen real estate than phones and users expect a different (better) experience when using mobile applications for this form factor.
