A shared calendar app helps families, couples, roommates, and small teams see the same schedule without relying on scattered messages. The right choice depends on who needs to edit events, which devices people use, and whether the calendar is for home, work, or both.
This guide compares shared calendar apps that fit English-speaking users: TimeTree, Google Calendar, Microsoft Outlook, Cozi, and Apple Calendar. If you need to arrange meeting times with people outside your household or team, also see Best Scheduling Apps.

How to choose a shared calendar app
A shared calendar app should do more than store events. For shared use, notifications, edit permissions, comments, and cross-device support matter just as much as the calendar view itself.
| What to check | Why it matters |
|---|---|
| Sharing method | Email invites, shared links, family accounts, or workspace accounts |
| Notifications | Everyone needs to see added, changed, and upcoming events |
| Permissions | Some people may need edit access, while others only need to view |
| Comments and notes | Useful for pickup details, meeting notes, or event-specific decisions |
| Device support | iPhone, Android, Mac, Windows, and web support can decide the best fit |
| Private calendars | You should be able to separate personal events from shared events |
Families usually need a simple app everyone can understand. Work teams usually need permissions, desktop access, and integration with email or video meetings. Couples and roommates often need fast notifications and a clear shared view.

TimeTree

TimeTree is a strong choice when several people need one shared calendar and event-level comments. It works well for families, couples, friend groups, and small communities where schedule changes often need a short conversation.
Choose TimeTree if you want shared calendars to feel lightweight and social instead of like a corporate scheduling tool.
Google Calendar

Google Calendar is the easiest pick when the people involved already use Gmail or Google Workspace. You can create separate calendars for work, family, personal events, and projects, then share each one with different permissions.
It is especially useful when you also use Google Meet, Gmail, or shared Google accounts. For purely family-oriented planning, it may feel less warm than TimeTree or Cozi, but it is powerful and widely understood.
Microsoft Outlook

Microsoft Outlook is best when calendar sharing is tied to email, meetings, and Microsoft 365. It is a natural fit for companies, schools, and teams that already use Outlook mail or Teams meetings.
Outlook can also work for household calendars, but its main strength is work. If you need shared availability, meeting invites, and email in the same environment, it belongs near the top of the list.
Cozi
Cozi is a family organizer built around a shared family calendar, reminders, shopping lists, and household planning. For English-speaking readers, it is a better family-focused option than LINE WORKS, which is more tied to workplace communication in Japan and nearby markets.
Choose Cozi if your main goal is managing school events, practices, appointments, meal planning, and household tasks in one place.
Apple Calendar

If everyone involved uses Apple devices, Apple Calendar can be enough. You can share iCloud calendars without installing another app, and events sync across iPhone, iPad, and Mac.
The limitation is mixed-device households. If Android users need to participate, TimeTree or Google Calendar is usually easier.
Best picks by use case
| Use case | Best picks |
|---|---|
| Family calendar | Cozi, TimeTree, Apple Calendar |
| Couples or roommates | TimeTree, Google Calendar |
| Google-centered workflow | Google Calendar |
| Work meetings and email | Microsoft Outlook, Google Calendar |
| Apple-only household | Apple Calendar |
| Mixed iPhone and Android users | TimeTree, Google Calendar, Cozi |
If you are unsure, start with the environment people already use. Google Calendar is easiest for Google accounts, Outlook is best for Microsoft 365, Cozi is strong for family logistics, and TimeTree is friendly for shared calendars with comments.

FAQ
Can other people see all of my events?
You can usually choose which calendar to share. Keep private events in a personal calendar, then share only the family, couple, project, or team calendar.
What is best for iPhone and Android mixed households?
TimeTree, Google Calendar, and Cozi are easier for mixed-device groups than Apple Calendar.
Should work and family calendars be in the same app?
It can work, but notification settings and visibility can get messy. Many people keep work in Outlook or Google Calendar and family logistics in TimeTree, Cozi, or Apple Calendar.
Summary
The best shared calendar app depends on who is sharing the schedule. TimeTree is friendly for families, couples, and groups. Google Calendar is the safest all-rounder. Microsoft Outlook is strongest for work. Cozi is built for family organization in English-speaking markets. Apple Calendar is enough when everyone uses Apple devices.
Do not try to put every event into one shared view. Keep personal events separate, share only what needs to be shared, and the calendar will stay useful longer.
