Trunk, the No-Login Travel Planner

Field notes

Trunk organizes trips as day-by-day cards containing timed places, transport, meals, reservations, costs, links, and notes. Its sharing model uses a compressed URL that recipients can reportedly open and edit without signing in, while the page says data remains in the URL rather than on a server. The sample covers a Hokkaido itinerary and shows a three-person expense total of ¥117,000; the feature list also includes timezone conversion, foreign-currency handling, printable packing lists, and travel-specific list templates.
