AppController is a powerful, easy-to-use app that enables users to access Windows applications from iPads and iPhones. Windows applications accessed via AppController retain all their features and functions and appear as though they are running locally on the iOS device. AppController maintains a high degree of usability by automatically touch-enabling Windows applications. Intuitive, multi-touch gestures allow users to interact naturally with Windows applications even though the device lacks a mouse and keyboard. The Auto-Zoom feature detects the section of the screen currently active in the application and automatically zooms-in on that area, making it easier to tap user interface elements. The device's onscreen keyboard opens automatically whenever an application can receive text input. AppController is free, but it requires a Windows computer running remote access software that is compatible with AppController. Contact your system administrator to determine if your company's Windows application servers support AppController.
