Teamup Calendar

Teamup Calendar is a shared calendar for groups that helps you organize people, schedule work, manage availability, and share events securely. Accessible from mobile apps and browsers, it offers a free basic version suitable for small teams, families, clubs, or evaluations, with more advanced enterprise features for larger organizations.

Key features include viewing and updating multiple sub-calendars, centralized calendar management, nine levels of access permissions, custom fields, attachments, event signups, and the ability to assign one event to multiple sub-calendars. It supports discussions, timezone-aware collaboration, a central dashboard, maps integration, a widget, offline read access, dark mode, and multilingual support. Enterprise options include single sign-on (SSO). The browser-based admin interface is where full permissions are configured.
