Citrix Doc Finder is another great application and a great addition for iPhone users. It allows easy access to documents stored in the users home folder. Citrix Doc Finder is a feature of Citrix Recever for iPhone that makes it easy for users to find and open the Enterprise docs they need from their mobile device.

Application Resolution

To optimize the experience for the iPhone display, Citrix recommends publishing Doc Finder to 480x800(or use the -i option in the file location dialogue), so the Doc Finder UI fits the iPhone screen. Other applications we recommend publishing the applications at 720 x 1080. This will render the application clarity to accommodate the iPhone screen size and resolution. In most cases the user can zoom and pinch to their desired magnification level. It is suggested to experiment for different applications to achieve optimal user experience.
