Release notes

A native feel on iPhone and iPad (iOS)

The iOS app was rebuilt to feel at home on Apple devices. iPhone now has a proper tab bar instead of a side drawer and a floating button, menus open as action sheets, and the event, task, filter, and settings screens use native iOS forms and pickers. iPad gets its own layout with pickers and menus that open as popovers anchored to what you tapped, instead of a stretched-out phone screen.

Your older events show up (iOS, Android)

Server calendars only pulled a narrow slice of recent history, so events from more than a few months back could be missing for no obvious reason. The app now loads history as you scroll to it, and a new Sync history setting under Settings > Sync lets you choose how far back to keep: three months, one year, two years, or everything. An event with no title is no longer dropped either. A new Sync diagnostics screen, in the same place, shows how many events each calendar fetched and saved on its last sync, so a calendar that isn’t showing everything is easy to spot. Thanks to Ratha for the report.

Tasks on more CalDAV servers (Desktop, iOS, Android)

Some servers, such as Fastmail, don’t advertise task support on a calendar even when they accept tasks. A new per-calendar Allow tasks option turns tasks on for those calendars, and it checks with the server before switching on so a calendar that genuinely can’t hold tasks won’t leave one stranded. If a server does reject a task, it’s kept safely on your device instead of disappearing. Thanks to Ratha for the report.

More reliable task sync on desktop (Desktop)

Tasks now sync both ways as dependably as events. A task or event deleted on another device is removed on the desktop too, unsynced items show a small pending indicator, and you can set a default calendar for new tasks.

Fewer duplicate and stuck accounts (Desktop, iOS, Android)

The same CalDAV account added on two devices, or typed a little differently each time, is now recognized as one account instead of being duplicated. Deleting a CalDAV account removes it cleanly, instead of leaving behind an entry that still tried to sync. Providers that redirect their CalDAV address, Fastmail among them, are also found more reliably when you add them. Thanks to Ratha for the report.

Offline changes keep syncing (iOS, Android)

A change made while offline, or a save that didn’t reach the server the first time, is now retried automatically until it lands, rather than being left behind.

Search your tasks and reminders (iOS, Android)

The Tasks and Reminders tabs now have search, so you can find an item by name without scrolling.
