Never ever forget anything again!
Journey is a program to pack your suitcase. You can enter all the things to take along, sort them into categories, enter a quantity if you like, and finally print out the check list.
But the interesting thing about Journey is that the next time you plan your journey, you will start with all the things you took along in any previous trip, and you only have to choose which things to take again.
So you cannot forget anything anymore, if you have once put in your bags.
