Event guests or organization members don't even need to be on DoorList yet-- you can add them by phone number so that all of their events and organizations will be there when they make an account.
DoorList is the app for group chats, event planning, organization management, attendance, and access control.
Making events is simple with DoorList, as you can add users individually or add an entire organization.
Event hosts can be sure that each person they put on the list will only correspond to one actual entry.
The app creates a unique QR Code that represents the user and prevents screenshots.
