Slotr handles time slots, sign-ups, waitlists and reminders, so you can focus on actually meeting up. One link, one overview, half a minute of work.
No credit card · GDPR-proof · Hosted in the EU
Slotr is one tool that takes the shape of whatever you need. Pick your situation and see exactly what your attendees see.
Dietary wishes, which council member, staying for dinner or not. You set up the fields you need and get the answers back in one tidy overview. No email threads, no separate spreadsheet.
Set up the time slots once and let parents pick for themselves. Double bookings cannot happen, because a booked slot disappears from everyone's screen straight away.
Plan the shifts once and add the names you already know. Those are shown for information and do not count towards capacity. Everyone else sees at a glance where a gap is left, and fills it themselves.
When it is full, the page keeps working. Whoever cancels automatically makes room for the next person on the waitlist, message included. Even when someone brings a plus one, because the waitlist moves up by party size.
Filter by event or status, search by name, edit details or resend a confirmation. And when the caterer wants a list, the Excel button hands over every registration including the answers to your own fields.
