Stowaway
A packing list that remembers so you don't have to. It tracks what you've bought, what's still in transit, what's already in the room, and what your roommate is bringing — the four things a checkbox can't tell you apart.
Built for dorm move-in, and it works just as well for a trip or a move. Free, with no sign-up.
