LastLook: pre-departure packing gap reminder

Reuse past trip lists offline and surface everything you haven't packed before you leave

Problem

People remember the big items but forget chargers, ID cards, or a book, and things still in use right before departure are the easiest to miss. A poster on r/SomebodyMakeThis explicitly wants an app that reuses a previous trip's list, adjusts quantities, works offline, checks items off, and shows a final Missing Items view.

Solution

An offline-first checklist app: clone lists from past trips, tweak quantities, check items off, and pop a consolidated 'still missing' view before the departure time you set. Includes list templates and simple sharing of one list.

Users

Frequent business and leisure travelers, family trip organizers, outdoor hobbyists packing gear

MVP

Why now
