Calnio vs Notion Calendar

You are happy to open a separate calendar app to see your Notion dates. It is free, it is made by Notion, it runs on Mac, Windows, iPhone and Android, and you can edit a database item there. If that is all you need, you do not need Calnio.

You want the dates inside Apple Calendar itself, the app your iPhone already opens, with alerts on your lock screen and your wrist. Notion Calendar keeps your database inside its own app.

Calnio puts them in an iCloud calendar, so they are in Apple Calendar on your iPhone, iPad, Mac and Apple Watch, and on iCloud.com.

Notion Calendar shows them in Notion Calendar. Notion's help center says the database is not shown in Google or iCloud calendar.

Calnio, with two-way switched on: move, rename or delete the event in Apple Calendar and the page follows. Two-way comes with the paid plan and the trial.

Notion Calendar lets you edit the title, the date and several other properties of an item, if you can edit the database.

Calnio turns a new event in a sync's own calendar into a new page, when two-way is on. Repeating events and invitations never become pages.

Notion says importing Google Calendar events into a Notion database is not yet possible.

Calnio writes real events into Google Calendar too, one calendar per database. Not Outlook.

Notion Calendar shows Google, iCloud and Outlook calendars together.

Calnio is free for one database, one way, and $3.99 a month for two-way and every database, the first 7 days free with no card.

Notion Calendar is free.

Calnio: sign in with Google, connect Notion, add an iCloud app-specific password, tick databases. Nothing to install.

Notion Calendar: install the app, connect your calendars (iCloud takes an app-specific password there too), then add the database from the sidebar, which works on desktop and web only.

The default alert times you set in Calendar apply to Calnio's events, so a due date can reach your lock screen or your wrist.

A Calnio calendar is an ordinary iCloud calendar. You can colour it, hide it or share it, and it shows up wherever your iCloud calendars do, Notion Calendar included.

Calnio also syncs a Notion database with a Todoist project: title, due date, done and priority.

No. Notion's help center says a database added to Notion Calendar can be viewed there only, not in Google or iCloud calendar. The dates stay inside the Notion Calendar app.

Calnio writes them into an iCloud calendar, so they are in Apple Calendar on your iPhone, iPad, Mac and Apple Watch.

Yes, Notion offers it for free. If seeing your Notion dates beside your other events in a separate app is enough, it costs nothing and you do not need Calnio.

Yes. A calendar Calnio makes is an ordinary iCloud calendar, and Notion Calendar shows iCloud calendars, so it appears there too. If you also add the same database in Notion Calendar, you will see each date twice.
