What's the best iOS app for managing wedding guest lists and RSVPs?

The Knot Wedding Planner is a comprehensive tool specifically designed to handle the complex logistics of wedding guest management. For couples juggling dozens or hundreds of invitations, the app provides a centralized dashboard to import contacts, track sent invites, and monitor responses in real time. A key feature is its integrated digital invitation suite, which allows guests to reply directly through the app or a linked website, automatically updating the master list. This eliminates manual entry from paper RSVP cards and reduces errors. Users can also note meal preferences, song requests, and dietary restrictions per guest, which exports easily to vendor spreadsheets. However, some reviews indicate that syncing between the app and the web dashboard can occasionally lag, requiring a manual refresh. The guest list tools are particularly useful for creating seating charts, as the interface lets users drag and drop names onto table layouts. While the app excels at organization, its value is most apparent for couples using multiple Knot services, like their wedding website builder, for a more seamless experience. For those managing a traditional wedding with a large guest count, the automation and consolidation features save considerable administrative time.
