It syncs directly with Google, Outlook, or Apple Calendar, placing all invitations and updates in the user’s existing calendar view, and automatically logs RSVP responses into a Google Sheet for easy tracking.

Problem
Organizers often have to manage separate invitation tools, notification streams, and manual RSVP tracking, which creates friction and increases the chance of missed responses. Guests may also be required to create accounts to view event details, adding another barrier to participation.
Solution
Dunbar integrates event scheduling directly with users' existing Google, Outlook, or Apple calendars, eliminating the need for a separate invitation platform. Event links can be shared via email, SMS, QR codes, or popular messaging apps, and guests can view the event without creating an account. RSVP responses are automatically recorded in a Google Sheet, streamlining attendance tracking. The platform also supports custom splash images and accepts a variety of photo formats, simplifying event promotion. By consolidating scheduling, notification, and response collection into the calendars organizers already use, Dunbar reduces administrative overhead and improves the attendee experience.
Target Audience
Primary users are individuals and small groups who already use Google, Outlook, or Apple calendars to organize gatherings, such as social clubs, community organizers, and informal event planners.
