There are several ways you can add fellow travelers to a trip or manage collaborators.
Invite others while creating a trip
When crafting your next adventure in the Lambus app, you have the power to invite travel companions straight from the trip creation stage. Simply input the email addresses or usernames of your friends and family, and they will promptly receive invitations to join your travel endeavor.
Invite others from the “My trips”-Overview
For this version, you don't even have to open the trip. Just tap on the plus button in the upper right corner of the tile and add fellow travelers by email or username. They'll receive an invitation to join the trip. Or share the PIN Code with which they can join a trip. Alternatively, your fellow travelers can also scan the QR code displayed.
Invite others from the trip overview
Or you can open the trip you want others to participate on. You can now find the same Plus-Button in the middle of your trip header image.
Invite others from the Trip Settings
Tap on the gear in the upper right corner of the Trip Overview to enter the Trip settings. Then scroll down to the top item "Attendees". Tap on "Manage" to manage fellow travelers or on "Invite" to add fellow travelers. As in the previous examples, you can add fellow travelers by email, username, PIN or QR code.
