'App' is a modern word for '(computer) application' -- a program such as Word, Excel or whatever. It was first used 2-3 years ago, mainly by young people, but is now used very commonly.

Your text means that the manufacturers have produced a basic version of the application and then produced a second version of it for professional (business) users, which has extra features so that the application can do more things.
