Companies are now using mobile applications (apps) in unique ways, and many companies are creating their own internal app stores. For example, the pharmaceutical company Pfizer has an app that helps employees who are traveling find and contact other Pfizer employees who are also traveling. Aflac, an insurance company, has an app that allows claims adjusters to see data and coordinate insurance claims on a mobile device without having to go to a computer and log on to the main enterprise system. For disaster recovery, Deloitte created an app called Bamboo, which can push emergency information out to employees' smartphones in the event of an emergency. Deloitte is implementing the app internally, and in the future, the firm plans to offer it to its customers. The military is also a major potential user of specialized mobile devices and apps. Harris, an electronics and communications company, is working on an app for tablet computers, such as Apple's iPad, to control the remote camera on an unmanned aerial vehicle. While there are durability issues with using a commercial tablet in harsh environments, it could make economic sense to use a $400 tablet in a rugged case instead of a $10,000 wireless receiver
