Web: It's always a good idea to have a checklist when you are travelling so you don't forget anything, but creatimg one can be a hassle. What To Pack is a simple Web app that auto-generates a starter checklist based on your requirements.
First you need to set your preferences: male or female, how many days you are going for, what your destination's climate is like, if it's domestic or international, and what kind of stay you are planning (skiing, business, beach, camping). Based on this, What To Pack generates a packing list across categories including clothing, money and documents, equipment, electronics, beach and many more. Select the items you want to include in your final checklist and hit the 'Print List' button to get only those items in a checklist that you can tick off.
