Cloud Calendars vs Notion Calendar (Cron) on iOS
Notion Calendar (formerly Cron) is free, ad-free, and unbeatable if your tasks and meeting docs live in Notion databases and you work primarily on Mac, Windows, or Web with keyboard shortcuts. Cloud Calendars is purpose-built for iPhone and iPad users who want instant native iOS iCloud/CalDAV access without generating Apple app-specific passwords, full Month and 12-month Year touch grids, side-by-side calendar columns, and Apple WeatherKit hourly forecasts. Arte Soft develops Cloud Calendars and publishes this comparison.
Feature-by-Feature Comparison Matrix
| Capability | Cloud Calendars | Notion Calendar (formerly Cron) |
|---|---|---|
| Signature strength | Touch-first iOS Multi-column/Month/Year grids + Apple WeatherKit station | Two-way Notion database date items, command bar & desktop/web speed |
| iPhone & iPad views | Day, Week, Month, 12-month Year, List & Multi-calendar column view | Mobile Day/Multi-day & agenda focus; lacks iOS 12-month Year or per-calendar column split |
| iCloud connection setup | Instant via iOS Calendar permission—no Apple app-specific password needed | Requires generating an Apple Account app-specific password for Notion’s servers |
| Weather forecasts | Built-in WeatherKit hub (hourly, 10-day, wind/gusts, UV, rain) + hourly grid icons | No built-in weather forecasting |
| Notion docs & databases | No Notion workspace integration | Link Notion docs to meetings and drag Notion database deadlines on your timeline |

| Account-free local mode | Create on-device local calendars with zero cloud login | Requires signing in with a cloud calendar / Notion account |
On-Device EventKit vs Cloud-Server Account Sync
Because Notion Calendar synchronizes your profile across Web, macOS, Windows, iOS, and Android from Notion’s cloud infrastructure, adding Apple iCloud requires generating an app-specific password at appleid.apple.com so Notion’s backend can access your iCloud CalDAV data.
Cloud Calendars runs locally on iPhone and iPad, reading iCloud, custom CalDAV servers, and subscribed ICS feeds straight from Apple’s on-device EventKit store with zero app-specific passwords, while using direct OAuth for Google (Free) and Microsoft (Premium).
Account Sync, Protocol & Platform Support
| Provider / Dimension | Cloud Calendars | Notion Calendar |
|---|---|---|
| Google Calendar | Sign in with Google OAuth + Google Meet links (Free) | Deep multi-account Google OAuth + Meet/Zoom conferencing |
| Microsoft 365 / Outlook | Sign in with Microsoft OAuth + Teams (Premium) or via iOS Exchange | Direct Microsoft Outlook / 365 OAuth connection |
| Apple iCloud & CalDAV | Direct on-device iOS EventKit access for iCloud & any CalDAV server (Free) | iCloud via Apple app-specific password; no generic custom CalDAV setup |
| ICS URL Subscriptions | Displays iOS subscribed ICS calendars directly on iPhone & iPad | Displays feeds already subscribed inside connected Google/iCloud/Outlook accounts |
| Supported Platforms | iPhone & iPad (iOS / iPadOS 18.0+) | macOS, Windows, Web, iOS & Android |
| Offline & Privacy Model | Zero-account local calendars supported; iCloud stays on-device via EventKit | Cloud-relayed account sync across web/desktop/mobile |
Pricing and Picking the Right Tool (or Pairing Both)
Notion Calendar is $0 with no ads. Cloud Calendars is also $0 for Google sync, iCloud access, all 5 views, WeatherKit, and Home Screen widgets—with optional Advanced ($4.99/year) to remove ads and Premium ($49.99/year) for Microsoft Calendar + Teams.
Many people run Notion Calendar on their laptop for Google + Notion project boards while keeping Cloud Calendars on their iPhone and iPad for Month/Year grids, iCloud family visibility, Live Activities, and hourly weather.

Touch-Native iOS Views vs Desktop-First Ergonomics
Notion Calendar shines with a trackpad and `Cmd+K` shortcuts on a 14-inch display, whereas mobile screens benefit from zooming out to a readable Month chip grid, a 12-month Year overview, or side-by-side per-calendar Day columns.
Cloud Calendars also adds iOS 18 Lock Screen Live Activity countdowns and combined date-and-weather Home Screen widgets.
Running Notion Calendar on Laptop + Cloud Calendars on iPhone
Because both apps talk to your underlying Google or Microsoft accounts, using Notion Calendar on desktop and Cloud Calendars on iOS creates zero data conflicts—every meeting synced to Google appears in both clients.
Just disable mobile notifications in one of the two iOS apps so you never receive double alerts.
