Sebastian is the group trip planner for friends who save places everywhere — with just one shared plan. Share links from online. Sebastian finds the place, you confirm it, and it lands on the trip. Everyone plans in the same workspace. MAP TOGETHER See every stop on a shared map. Tag places with different labels with Food, Sights, or what ever you want). SWIPE AND DECIDE Stop arguing in the group chat. Swipe through places, vote, run polls, and see what the group actually wants. SPLIT THE BILL Log expenses, attach receipts, and settle who owes whom —multiple currencies with self define exchange rates supported. INVITE YOUR PEOPLE Create a trip, share a link or code, and plan live together. Changes stay in sync for the whole group.

  • This app hasn’t received enough ratings or reviews to display an overview.

Copy a map without joining the trip. Share a preview link — anyone can look at your pins and copy them into a trip of their own. Give each label a pin or a cat claw. The icon uses that label’s color. More cities to plan: Busan, Jeju, Chiang Mai, Phuket, Da Nang, and others across Japan, Korea, Taiwan, and Southeast Asia.
