WannPassts

WannPassts is a German web tool for coordinating whole days, weekends and continuous date ranges in private groups. The interface and help content are currently available only in German. Organisers propose 2 to 30 options and share an invitation link. Participants rate every option as 'Passt' (works), 'Notfalls' (if needed) or 'Geht nicht' (doesn't work), without creating an account or entering an email address. The product is free, has no paid tier and contains no advertising. Polls and responses are deleted automatically 30 days after creation. It intentionally does not schedule meetings at specific times of day.
