I'm not sure it would, unless the app development were to be significantly different. People sometimes underestimate the cultural differences.
The example I like to give is the one given by John Hooker, who taught comparative culture at CMU. As it is, U.S. jokes are often not funny to many continental Europeans. Chinese humor is of a whole other bent.
Another interesting comparison point are Japanese websites, which are borderline unnavigable (to me) because they avoid any use of larger fonts.
