The best free calendar app depends on what your team needs to manage. Some apps focus on meetings and personal schedules, while others help teams connect dates to tasks, owners, and project details.
Here are a few common options:
Asana: Good for teams that need a shared calendar connected to task management, project owners, approvals, files, and deadlines.
Google Calendar: Good for teams that use Google Workspace, Gmail, and shared calendars for meetings, reminders, and event scheduling.
Microsoft Outlook: Good for teams that use Microsoft 365 and Outlook Calendar for meetings, work schedules, and team availability.
Apple Calendar: Good for Apple users who want a simple calendar app for events, reminders, birthdays, and iCloud calendars.
Simple Calendar: Good for Android users who want a basic offline calendar with a monthly view.
Fantastical: Good for Apple users who want day views, widgets, calendar sets, and a more detailed personal scheduling experience.
Morgen: Good for people who want to plan their day with calendars, tasks, booking pages, and scheduling links.
Todoist: Good for people who want a to-do list app with task deadlines, recurring tasks, and calendar-style planning.
For team projects, Asana works better when your shared calendar needs more than dates and events. In Asana, calendar items connect to tasks, owners, due dates, comments, files, approvals, and project views. That helps teams manage the work behind each deadline, not just the date on the calendar.
Use a standard calendar app when you only need to schedule meetings, appointments, or events. Use Asana when your team needs to plan deadlines, assign owners, track project tasks, and manage work from request through completion.
