7 Best Calendar Apps for Android in 2026

Having a reliable calendar app is essential for staying organized on Android—whether you’re juggling work meetings, personal plans, or shared schedules. While Google Calendar comes preinstalled on many devices, there are excellent alternatives that offer better privacy, more powerful views, smarter task integration, or easier sharing.

In this updated 2026 guide, we’ll cover seven of the best calendar apps for Android, with refreshed features and official pricing so you can pick the right one quickly.

How did we choose these calendar apps?

We focused on what actually matters in day-to-day Android use in 2026—not just “can it create events?”:

1. Speed: Quick event creation, templates, and smart suggestions.
2. Views & widgets: Agenda, week, month, schedule, and home screen widgets that reduce app switching.
3. Sync: Works reliably with Google Calendar, Microsoft/Exchange, and shared calendars.
4. Reminders: Strong notifications and “don’t miss it” options.
5. Workflow fit: Whether it plays nicely with the rest of your system (tasks, planning tools, and team calendars).

A simple upgrade: Keep events and tasks aligned

If you only need a calendar, you can skip this. But if you also plan projects and tasks somewhere else, syncing is often the biggest quality-of-life upgrade you can make.

For example, many people plan in Notion—a flexible workspace where you can build databases for projects, tasks, and notes. The friction starts when your schedule lives in one app (Google Calendar or Outlook) and your plans live in another.

When your calendar and planning hub stay aligned, you get practical benefits like:

• No double entry: Update a date once, and it stays consistent.
• Fewer misses: Your mobile calendar notifications stay tied to your real plan.
• Clearer days: See time blocks (events) next to what you actually need to do (tasks).
• Less drift: Changes to meetings, deadlines, and time blocks don’t get lost.

1. Google Calendar

🥇 Best for: Most Android users
✨ Highlight: Best-in-class Google integration (Gmail, Meet, sharing)
💲 Price: Free | Google Workspace Business Starter from $7/user/month (annually)

Google Calendar is still the default recommendation for Android because it’s fast, familiar, and deeply connected to the Google ecosystem. Events from Gmail can surface automatically, sharing is painless, and it works well for personal, team, and family calendars.

✅ Pros:

• Excellent sharing + availability features for teams and families.
• Automatically surfaces useful context from Google services (like event details and relevant links).
• Strong integration with Google Meet and the wider Workspace ecosystem.
• Reliable recurring events, reminders, and multi-calendar support across devices.

❌ Cons:

• Privacy depends on your Google account settings and how comfortable you are with the Google ecosystem.
• Limited customization (views, styling, widgets) compared to dedicated “power calendar” apps.
• Some advanced business features are available only with paid Workspace plans.

2. Outlook Calendar

🥇 Best for: Microsoft 365 and Exchange users
✨ Highlight: Email + calendar + contacts in one place
💲 Price: Free | Microsoft 365 Business Basic from $6/user/month (annual billing)

Outlook Calendar is the obvious pick if your work runs on Microsoft 365 or Exchange. It’s built for scheduling with colleagues, handling invites smoothly, and keeping email and calendar in one workflow. It’s especially useful on Android when you need everything in one place.

✅ Pros:

• Great for meeting-heavy weeks: invites, updates, and work scheduling are smooth.
• Supports Microsoft accounts, shared calendars, and common enterprise setups (Exchange/Outlook).
• Helpful on mobile if you want inbox + calendar + contacts in one app.
• Plays well with Teams and Microsoft’s broader productivity stack.

❌ Cons:

• Less minimal than a dedicated calendar-only app (more features, more UI).
• Some admin/security features depend on your Microsoft 365 plan and organization settings.

3. Proton Calendar

🥇 Best for: Privacy-focused users
✨ Highlight: Encrypted calendar designed for privacy
💲 Price: Free | Proton Unlimited from $12.99/month (monthly plan, pricing varies by region)

Proton Calendar is a strong option if privacy is your top priority and you want a calendar built to protect your data. It covers the essentials—events, recurring items, reminders—without turning your schedule into an advertising profile.

✅ Pros:

• Privacy-first approach with encryption designed to protect event details.
• No ad-driven business model, so your schedule is not used for targeting.
• Clean UI with the core scheduling features most people need (recurring events, reminders, calendars).

❌ Cons:

• Fewer third-party integrations and collaboration features than Google/Microsoft ecosystems.
• Best value is usually when you want the broader Proton suite, not just calendar features.

4. aCalendar

🥇 Best for: Customization and offline-friendly planning
✨ Highlight: Detailed views, widgets, and fine-grained controls
💲 Price: One-time purchase (price varies by region)

aCalendar is a great pick if you want a traditional “power calendar” feel on Android: clear agenda/week/month views, strong readability, and the kind of customization that helps your calendar match how you think.

✅ Pros:

• Highly customizable views (including agenda/week/month/year) and strong readability.
• Great widget support and quick actions for faster daily planning.
• Useful extras like flexible recurrence rules and fine-grained display settings for multiple calendars.

❌ Cons:

• More settings than most calendar apps, so it can take a bit to tune it to your preferences.
• Not designed as a team “suite” like Google/Microsoft—more for personal power users.

5. Business Calendar 2

🥇 Best for: Agenda + widget power users
✨ Highlight: Pro-style planning views and widgets
💲 Price: Free | Pro version available (one-time purchase, price varies by region)

Business Calendar 2 is a favorite for people who live in their agenda view and want widgets that make the day visible without constantly opening the app. If Google Calendar feels too “simple” for heavy scheduling, Business Calendar-style apps are often the next step.

✅ Pros:

• Excellent agenda/week views and home screen widgets for “at a glance” planning.
• Fast editing tools (drag-and-drop, templates, and quick actions depending on setup).
• Great for calendar-heavy workflows where you want dense information on screen.

❌ Cons:

• Some of the best features are gated behind the paid Pro version.
• Collaboration depends on your underlying calendar provider (Google/Exchange/CalDAV), not the app itself.

6. Any.do

🥇 Best for: Tasks + calendar in one view
✨ Highlight: Daily planner that blends schedule and to-dos
💲 Price: Free | Premium $4.99/month (billed annually)

Any.do is a strong option if what you really want is a day planner: see your calendar events and tasks together, then work through the day without bouncing between apps. For many people, that reduces friction more than switching calendar brands.

✅ Pros:

• Daily planner view is excellent for “what’s next?” execution.
• Strong task features (recurring tasks, reminders, lists) alongside your calendar.
• Helpful for routines and personal productivity when you want tasks and schedule together.

❌ Cons:

• Less ideal if you want an advanced calendar-only experience with dense views and scheduling controls.
• Some features and integrations are limited on the free plan.

7. TimeTree

🥇 Best for: Sharing and collaboration
✨ Highlight: Shared calendars + coordination around events
💲 Price: Free | Premium $4.49/month (or $44.99/year)

TimeTree is built around shared schedules—perfect for families, couples, or small teams coordinating day-to-day life. The biggest win is how easy it makes it to keep everyone on the same page, with shared calendars and coordination centered around events.

✅ Pros:

• Excellent shared calendar experience for non-technical users.
• Great for family logistics, roommates, and small teams.
• Event-based notes/comments make it easier to coordinate details in context.

❌ Cons:

• Not the best fit if you need enterprise scheduling features or complex work permissions.
• Advanced features are behind Premium, and free plans may include promotional prompts depending on the region.

Conclusion

The best calendar app for Android depends on your ecosystem and your workflow: Google Calendar is the safest all-around choice, Outlook wins for Microsoft-heavy work, Proton is great for privacy, and apps like aCalendar or Business Calendar are perfect if you want more control and better views. If sharing is the priority, TimeTree is hard to beat.

And if your calendar is just one piece of your system (for example, you plan projects and tasks in Notion but execute on Android), the biggest upgrade is to make sure your tools don’t drift out of sync.
