Rome Trip Planner
Zero-backend, offline-first PWA for coordinating a family trip to Rome — works on the plane, syncs across phones via manual export/import.
Every group travel app assumes you want to create accounts and have cell service when you land. I wanted an itinerary our family could edit on the flight over: an installable mobile web app that stores everything locally on the device and shares updates between phones by passing a tiny snapshot file over AirDrop or text.
