We build custom cross platform mobile GIS and location based mobile applications. There is our one sentence elevator sales pitch. But what is this cross platform business? Put simply write one code base and run it across multiple platforms. So take your beautiful mobile web application written in HTML5/Javascript convert it to an installed app using Phonegap. Distribute it to the various app stores and you are done. You have created a hybrid mobile app. So why all the fuss over native apps? These are apps written in the language of choice of a specific platform; Objective C for iOS, Java for Android. So multiple versions of the same app need writing for each platform. These sound expensive to write and maintain. As with all things there are advantages and disadvantages of each approach.
