This powerful app uses your organization’s Citrix XenApp infrastructure to remotely access any Windows application or document from your iPhone. Whether you need to edit a document, approve expenses, or even join a webinar, you can do it all from your iPhone with Citrix Receiver. Of course, you’re limited by the iPhone’s screen size, which means you’ll have to do a lot of zooming and scrolling with some applications. And since the applications are located remotely, you’ll need a 3G connection or Wi-Fi for reasonable performance. Your organization will also need to have a XenApp solution in place for this app to work—a large investment for many organizations.
