calfeeds use the open iCalendar standard (ICS). You can therefore subscribe with practically any calendar app:
- iPhone & iPad: Apple Calendar, directly via the subscribe link. Guide
- Android: via the free calovo app (Android 8.0 or newer) or via your Google Calendar. Guide
- Google Calendar: add by URL in the browser, syncs to all devices. Guide
- Mac: Apple Calendar via “New Calendar Subscription”. Guide
- Outlook: on the web, in the new and in classic Outlook (“Subscribe from web”). Guide
- Thunderbird and others: any app with iCalendar support (“New Calendar” → “On the Network”).
Samsung devices work too: Samsung Calendar shows calendars you subscribed to via your Google account.
How do I spot the right option?
Wording differs per app. Look for options like “Subscribe”, “Add subscription calendar”, “From URL”, or “Subscribe from web”. Important: always pick the subscription – not the one-time file import, which never updates.
