Kaikōdo

Kaikōdo is a free group travel planner that puts your whole trip in one app, so you don't need five different ones.

• Shared trips: invite your group, with admin, editor and viewer roles • Day-by-day itinerary by city • Spots: save places from Google Maps before you travel; when you create a trip to that destination, they're imported automatically • Tickets & documents: keep flight, train and hotel PDFs in the trip — open them once and they're available offline • Shared expenses: split costs between members in any currency and see who owes whom • Built-in translator • Notes and push reminders for flights and plans

100% free. No Pro plan, no credits, no ads. Available on iPhone, Android and web.
