What's New in Calendar 366 · Events & Tasks

4.1.1

October 27, 2026

Calendar 366 now supports iPhone Duo — plus redesigned event and task details, a new app icon and many improvements. **New** • Change duration in week and day view — drag the handles in the right corners of an event to adjust start and end, snapping to quarter hours • Maps app picker — choose which maps app opens a location • Location in lists — show it in full, truncated to one line or not at all (Settings → View) • Search now also finds tasks without a date and completed tasks • Duplicate events by drag and drop — hold Option (⌥) while dragging to copy an event (hardware keyboard). Also works for events that can't be moved **Bug Fixes** • Fixed a rare crash when syncing certain shared Microsoft calendars • CalDAV/Fastmail: if the server rejects the sync token, the calendar is now reloaded instead of stopping with an error • Fixed an issue where a quick change in the event preview (such as calendar, availability or reminders) that was cancelled or failed in the series dialog did not show the saved state • Fixed an issue where accepted invitations from other organizers appeared striped in month and agenda views • Fixed an issue where switching views with search open kept the next view filtered and brought back the old search text • Minor bug fixes

User reviews

Optisch super

Die schlechten Bewertungen sind ein Witz. Die App entwickelt sich hervorragend. Frisches Design und voller Funktionsumfang. Ich finde auch die Preisgestaltung fair. Irgendwie muss es sich ja lohnen, wenn man die ganze Arbeit reinsteckt.

Es gibt zwar noch einiges zu verbessern, aber wirklich bisher toll gemacht.

Danke! Bei Fragen oder Anregungen gerne melden: support@calendar366.com

the subscription disappeared

After the October 23, 2026 update, my family subscription stopped working. The subscription isn't showing up in the App Store and can't be restored. although the main account is still subscribed and hasn't updated the app's app area (which doesn't support the iPhone Duo), the subscription is still active. What does this mean? It's nonsense. I updated the app and lost my subscription

Apple Calendar on steroids

I paid for and used the old version of this app. Then a new version came out and I paid for lifetime almost immediately.

This is what Apple Calendar should have been. So many different ways to view your Calendar. Amazing looking, and actual useful widgets. A few bugs that I noticed have been squashed already.

Kudos to the Developer(s).

Not perfect, but the best I’ve used

I’ve had some problems - events entered on the phone sometimes are saved with the current date, not the correct date for the event, but overall I’m finding it useful, attractive and worth the $

Sehr sehr gute App

Nach langem hin und her, bleibe ich nun bei diesem Kalender. Ich habe auch die Lebenslang Version gekauft, da ich in dieser App eine sehr gute Entwicklung sehe.
Wenn es möglich wäre, würde ich mir wünschen, auch in den Agenda Buttons bei der Terminierung zusätzlich die Endzeit eines Termins zu sehen.
Ansonsten bisher Top.
