Xtify: "Geo-Relevant" Messaging for Android
With Xtify-enabled applications, messages can be customized and sent to users based on their exact location. For example, local search and discovery applications could send you messages about businesses close by. Shoppers could be sent mobile coupons as they walked through the mall. Restaurant guide applications could ping you with recommendations about top-rated nearby establishments. Travel apps could pop up interesting facts about landmarks, historical sites and other points of interest as you went sightseeing.
While obviously marketers are going to glom onto the opportunities a local-aware messaging platform like this offers, Xtify's SDK, as you can see in the examples above, could be used for more engaging mobile messages than just coupons, ads and geo-spam.

Why on Android First?
It's not surprising that Xtify launched first on Android instead of iPhone. Just prior to the platform's debut, Apple announced that location-aware ads would not be allowed in all of its mobile applications. Likely concerned with the potential for abuse, Apple posted a notice to their developer center reading:
"If you build your application with features based on a user's location, make sure these features provide beneficial information. If your app uses location-based information primarily to enable mobile advertisers to deliver targeted ads based on a user's location, your app will be returned to you by the App Store Review Team for modification before it can be posted to the App Store."

Android has no such restrictions due to its nature as a more open platform where apps don't have to go through a review process prior to arriving in the app marketplace. That should help Xtify get a head start since developers can simply take the SDK and run with their ideas without fear that their app will be rejected.
