DoorList

Wristbands and clunky guest lists are a thing of the past with DoorList, an app for group chats, planning, organization control, and entry scanning. DoorList creates a unique QR Code that represents the user and prevents screenshots. The time-based QR security means that by the time a screenshot is sent, it is already invalid. Event hosts can be sure that each person they put on the list will only correspond to one actual entry. DoorList was built for campus organizations and is the best way to allow your members to easily manage their social calendar

Making events is simple with DoorList, as you can add users individually or add an entire organization. Further, you can give +1's to others so that they can add their date or friends themselves. 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. You can even repeat past events by duplicating the entire list!
