DoorList occupies a practical niche in the event management category by focusing specifically on guest list handling and check-in operations. The application serves event organizers who need reliable tools for verifying attendees while maintaining smooth entry flows. Unlike broader event platforms that incorporate ticketing and promotion, DoorList concentrates on the critical last-mile process of getting guests through the door efficiently. Core functionality centers around importing guest lists from spreadsheets or manually creating entries, then using the mobile device to scan tickets or search names during check-in. The interface displays relevant attendee information including ticket type, plus-one status, and special requirements. Organizers can mark attendance in real-time with customizable status options, while the app maintains a running count of check-ins versus expected attendance. Offline functionality ensures operations continue regardless of venue internet reliability, with data syncing once connectivity resumes. In practical scenarios, event staff report the app reduces entry line bottlenecks at conference registrations, wedding receptions, and club events. The search function proves particularly valuable when dealing with alphabetical guest lists of several hundred names, eliminating frantic scrolling through printed sheets. Venue managers appreciate the ability to hand the device between multiple staff members while maintaining consistent record-keeping. The simple color-coded interface—green for checked-in, red for no-shows—provides at-a-glance status updates throughout the event. Early user feedback indicates satisfaction with the app's specialized focus, with comments frequently mentioning how it eliminates the awkwardness of paper list fumbling at entry points. Some organizers note the import process occasionally requires formatting adjustments when bringing in complex spreadsheets, though the basic CSV template handles most common scenarios adequately. The absence of built-in payment processing or promotional tools is noted as both a limitation and advantage, depending on whether users prefer specialized or all-in-one solutions. The application delivers effectively on its core promise of streamlined guest management, though organizations requiring integrated payment systems or marketing features would need supplementary tools. For straightforward event check-in responsibilities, DoorList provides a reliable, purpose-built solution that improves upon traditional methods without unnecessary complexity.
