Best Shared Calendar App to Try in 2025
1. Focuzed.io
Best For: People and teams who want their calendar to think with their brain, not against it.
Platforms: Web, iOS, Android
Focuzed.io redefines what a shared calendar should feel like — calm, intelligent, and energy-aware.
Instead of just showing you when you're available, it helps you figure out when you’re ready. Whether you’re a family managing ADHD, a remote team avoiding burnout, or a couple balancing deep work and quality time, this is the calendar that finally adapts to you.
Why It Stands Out:
- Energy-Based Reminders: Nudges you when focus peaks, reminds you to recharge when energy drops
- Wearable Sync: Pulls in real-time data from Apple Health, Google Fit, and more
- Energy-Aware Planning: Sync with Apple Health or Google Fit to plan around real energy, sleep, and recovery data.
- One-Task View: Visual Focus Bar replaces clutter with clarity
- Shared Focus Sessions: Plan deep work blocks with your partner or team
Perfect For: Remote workers, neurodivergent users, solo entrepreneurs, families with complex routines
Pricing: 14-day free trial → $9/month or one-time Lifetime Deal
2. Google Calendar
Best For: People who want something fast, familiar, and friction-free.
Platforms: Web, iOS, Android
It’s not fancy. But it works. Google Calendar is the backbone of many shared setups thanks to its clean interface, deep ecosystem integrations, and easy calendar sharing via email.
What Makes It Solid:
- Color-coded layered calendars (Work, Personal, Family, etc.)
- Simple invite permissions and shared access
- Native integration with Gmail, Meet, and Google Tasks
- Instant sync across all devices and time zones
Perfect For: Couples, roommates, teams already using Gmail
Pricing: Free
3. Cozi
Best For: Parents managing school pickups, soccer practices, and dinner plans — all at once.
Platforms: iOS, Android, Web
Cozi isn’t just a calendar — it’s a family ops center. It combines events, chores, shopping lists, and meal planning into one beautifully organized, color-coded system.
Why Families Love It:
- Assign colors to each family member
- Sync to-do lists, grocery runs, and meals
- Shared access for all devices
- Family journal feature to log milestones
Perfect For: Busy families, caregivers, co-parents
Pricing: Free (with ads) or Cozi Gold for premium features
4. TimeTree
Best For: Social planners who want to collaborate casually and visually.
Platforms: Web, iOS, Android
TimeTree feels like planning on a shared whiteboard — but with reminders, color codes, and real-time syncing. Great for roommates, long-distance couples, or small friend groups.
What It Offers:
- Shared events with built-in comment threads
- Multiple calendars for different groups
- Task notes and reminders per event
- Sleek, minimal interface
Perfect For: Couples, group trips, roommate logistics
Pricing: Free
5. Teamup
Best For: Large groups that need control over access and visibility.
Platforms: Web, iOS, Android
Teamup is designed for organizations managing resources more than just people — like event spaces, vehicles, or rotating volunteers. Think logistics, not just lunch plans.
Why It’s Unique:
- No-login share links (great for non-tech-savvy folks)
- Sub-calendars with fine-tuned permissions
- Visual timeline and scheduler views
- Easy public embeds
Perfect For: Nonprofits, event planners, large crews
Pricing: Free tier available (premium for more features)
6. Notion Calendar
Best For: Creatives and teams already living inside Notion.
Platforms: Web, macOS, iOS
This new standalone tool from Notion is perfect if your planning life is tied to your project work. It’s fast, clean, and deeply linked with Notion’s databases and docs.
Where It Wins:
- Plan timelines right next to content
- Connect events to tasks, docs, and workflows
- Sleek interface with keyboard-first UX
- Multi-calendar sync and drag-to-block flow
Perfect For: Makers, writers, editorial teams
Pricing: Free (beta release)
7. Outlook Calendar
Best For: Microsoft users who need structure and cross-platform syncing.
Platforms: Web, iOS, Android
Outlook Calendar is the natural choice for Microsoft 365 users. It handles delegation, meeting links, and layered access with a level of precision that makes it popular in corporate environments.
Where It Shines:
- Book and manage meetings with Outlook + Teams integration
- Calendar sharing with custom permissions
- Recurring events and automated reminders
- Built-in scheduling assistant
Perfect For: Corporate teams, administrative workflows, consultants
Pricing: Included with Microsoft 365
Final Thoughts: The Right Shared Calendar Can Change Everything
The best shared calendar isn’t just a place to dump events — it’s a system that brings order to your personal chaos and clarity to your team’s workflow.
Whether you’re a remote team looking for energy-aligned scheduling (like with Focuzed.io), a busy family juggling multiple routines (like Cozi), or just want something clean and collaborative (like TimeTree or Google Calendar), there’s a perfect fit waiting.
The key? Choose a calendar that not only syncs your time — but also respects it.
