Wherewhen
No more spreadsheet itineraries
Wherewhen is a trip planner that turns a loose list of places into a day-by-day itinerary. Drop the spots you want to visit onto a calendar and it fills in times, calculates travel between stops, and flags problems like closures or tight connections while you're still planning. Built for solo travelers and groups, it supports shared editing, idea voting, pinned reservations, and full offline access on your phone.
