Good apps for international travel w/o data

[dohmai]

New to Android here so don't know much about all the apps out there..

Looking for some suggestions on useful travel apps for traveling internationally, but apps that won't require data/connection as I won't have that.

As for I want the apps to do- well anything that will make travel easier! I really have no idea what type of apps are out there so I'm sure there are tons of things I can't even imagine but would be useful to have.

Thanks
