Calendar Apps (Consumer)

For calendar UI components and "Calendly clones" (Cal.com etc.) see calendars. This page covers desktop / mobile calendar clients for personal use.

The free defaults

• ★ Google Calendar — free; web + Android; the default underlying calendar for most knowledge workers.
• ★ Apple Calendar — free; macOS + iOS; clean, gets the job done; CalDAV / iCloud sync.
• Outlook Calendar — free with Microsoft account; the default in corporate Microsoft 365 shops.
• Proton Calendar — free + paid; end-to-end encrypted; pairs with Proton Mail.

Mac / iOS power-user paid apps

• ★ Fantastical — paid subscription; gorgeous; natural-language event entry ("Lunch with Pat Friday 1pm"); the Apple power-user default.
• BusyCal — paid one-time + subscription; long-running Mac calendar with custom views.
• Calendars by Readdle — paid + free; iOS-leaning; natural-language input.
• Timepage by Moleskine — paid; minimalist and pretty.

The Cron / Notion Calendar wave (2024+)

• ★ Notion Calendar — free (was Cron, rebranded 2024 after Notion acquisition); fast keyboard shortcuts, multi-account, time-block from Notion docs and tasks. The default new desktop calendar for many in 2025–26.
• ★ Amie — paid + free tier; tasks + calendar + email triage in one; Y-Combinator alum, growing fast.
• Morgen — paid + free tier; multi-account; cross-platform (Win/Mac/Linux/iOS/Android — rare!); strong privacy story.
• Vimcal — paid only; "fastest calendar"; built for execs / heavy-meeting people; vim-style keys.

Booking / "pick a time" links

For booking-page tools (Calendly, Cal.com, SavvyCal, Reclaim, Vimcal Hold, Microsoft Bookings) see the calendars page — that's where the side-by-side lives.

Calendar utilities

• Itsycal (Mac, free) — tiny menu-bar calendar.
• Stenway / WidgetSmith (iOS) — calendar widgets.
• Maccy / Raycast extensions — quick-glance "what's next" via launchers.

Self-host / OSS

• Tutanota Calendar, Proton Calendar — encrypted commercial.
• Radicale, Baikal — CalDAV servers (also linked from calendars).
• EteSync — encrypted sync for contacts + calendar.
• Thunderbird Calendar (Lightning, now built-in) — free OSS.

Pricing reality check

• Notion Calendar is fully free even though Notion AI / paid-plan users are upsold. The free tier is the product.
• Fantastical is one of the more expensive consumer subscriptions (~$57/yr) — only worth it if you live on Mac/iOS and use natural-language entry constantly.
• Vimcal runs ~$15+/mo — exec-priced.
• Morgen has a real free tier with multi-calendar support.
