FIX Dictionary 4.0 is a very intuitive and easy to use interface for the FIX 4.0 protocol specification that is used in financial software. The application displays all the fields in the protocol description sorted by tag number, tag name and listed by the message type. By clicking on any field in the application you get a view describing details like the tag number, tag name, data type, message types that the field belongs to, and the enums that the field represents.

By swiping horizontally on the screen of the iPhone you can flip the view to see a detailed description of the field. If the details do not fit on the screen, you can swipe vertically to use the scrollbar and read the details.
There is also an added search feature that helps you search fields by tag number and tag name. You can enter the tag number say 28, to directly go to the specific field description or you could enter a part of a string in the tag name like say "msg" to list all the fields that have the string "msg" in the tag name.
