I believe we have been through this discussion before, several times. But
in short: Unicorn aims at realizing the FEniCS vision of "...the goals of
generality, efficiency, and simplicity, concerning mathematical
methodology, implementation, and application.", for continuum mechancs
problems, using one implementation of one method for a wide range of
problems, extending the generality of currently available methods in this
area, concerning mathematical methodology and implementation.

FEniCS Apps, to me, sounds more like a forum for a wide range of
application oriented developers using FEniCS software tools, less focused
on a unifying mathematical methodology.

Good!
