Best free applications for collaborative trip planning?

There are several strong free options for collaborative trip planning. Wanderlog offers many of the core features groups need, including shared itineraries, saved places, maps and day-by-day planning, although some additional features may require a paid plan. Google Maps is one of the easiest completely familiar options because friends can create shared lists of restaurants, attractions, beaches and other places without learning a dedicated planning system. Google Docs or Sheets can also work surprisingly well for basic collaborative itineraries.

Stippl provides another travel-focused option for building and sharing trips. For group expenses, Splitwise and Tricount both offer useful free functionality. A good free setup for most friend groups is a collaborative itinerary app combined with a dedicated expense-sharing tool rather than trying to manage everything through a group chat.
