The best calendar apps in 2026
There is no single best calendar app. For meetings and invites, Google Calendar or Outlook. On Apple devices, Apple Calendar or Fantastical. For Notion users, Notion Calendar. To plan your own week in time blocks and actually finish it, Cutline, which is free and shows your Google, Outlook or Apple meetings inside the same week.
Most people need two things from a calendar: a place for meetings other people put there, and a plan for the hours that are theirs. Most apps below are great at the first. Pick by which of the two matters more to you, and remember they can work together.

The apps
1. Google Calendar
The default for anyone with a Google account. Strong at meetings, invitations, shared calendars and working on every device. It has no done state for a block, so the plan never becomes a record.
2. Apple Calendar
Built into every Apple device, syncs over iCloud and reads Google and Exchange accounts too. Simple and fast, with few planning features.
3. Microsoft Outlook
The calendar most companies run on, tied to Outlook mail and Teams. Best for scheduling with colleagues.
4. Fantastical
Known for typing events in plain language and a refined design across Mac, iPhone and iPad. Paid features come with a Flexibits Premium subscription; see their pricing.
5. Notion Calendar
A clean calendar that links events to Notion pages and databases.
6. Cutline
A weekly time-blocking calendar that scores what you finish: XP for finished blocks, cleared days, streaks and an opt-in weekly board. Google, Outlook and Apple calendars show inside it; payment links, a verified CV, jobs and a library of recipes and workouts are built in. Runs in any browser. See how it works.
7. Proton Calendar
Part of Proton's encrypted suite: events are encrypted so only you and the people you invite can read them.
