Sometimes it's hard to determine how many pairs of underwear you'll need when you're packing for a trip.
This app helps you determine the perfect amount by comparing the quantity against how many times you will have to wash them.
Inspired by Reed Kennedys "Pack Like a Nerd" that was featured at lifehacker.com.
