Our verdict on Tandem
Tandem is an online scheduling platform for schools, universities, and other calendar-driven organizations. It brings rooms, teams, groups, facilities, equipment, and events into a central calendar, with tools for conflict checking, role-based permissions, public and private events, website embedding, and subscriber updates. It is suited to organizations that coordinate shared resources across multiple departments or groups rather than individuals seeking a personal calendar.
The plan structure moves from basic calendar publishing to broader scheduling controls. The Free plan includes a single master calendar for admins, email updates, website integration, and connections to Outlook, Google, Apple, and Samsung Calendar. Pro costs $20 per month with monthly billing for up to five users and adds full conflict checking, fine-grained permissions, public and private events, unlimited calendar pages, integrations, and SMS updates. Annual billing is also available with a stated 5% saving. Enterprise costs $40 per month with monthly billing for up to five users and adds step-by-step approval workflows, facility rental, account customization, equipment inventory, transportation and work orders, and internal calendar reports. Annual billing is available for this tier as well.
Tandem’s strongest fit is shared-resource coordination where approvals and scheduling conflicts need formal handling. Its API can extend event data to other services, while integrations include Microsoft Accounts, Active Directory, RSS, XML, and CSV alongside the listed calendar services. Email, SMS, and in-app notifications support updates to participants and subscribers. External calendar distribution is one-way, so organizations needing two-way synchronization may prefer another calendar system. Choose Tandem for centralized institutional scheduling with permissions, approvals, and resource modules; choose an alternative if personal calendar workflows or bidirectional synchronization are the priority.
