The calendar you share with your partner, your family, or your team on iCloud simply doesn’t show up in most Windows apps — not even in some big-name ones. ZefirCalendar displays your iCloud shared calendars right in the tray, next to everything else. If half your life is planned on an iPhone and the other half on a PC, this is the bridge.
iCloud calendars on Windows: how it works, and how it compares
One click on the tray icon opens a flyout with iCloud, Google and Outlook in a single chronological list. No browser, no tab left open all day.
Connect iCloud, Google, Microsoft and ICS feeds in one window. Calendars someone shared with you show up next to your own, something Windows alone won’t do.
Title, time, target calendar and reminder right in the flyout. The event lands in the right account and shows up on your iPhone in seconds.
Meeting moved? Change it in the flyout and it syncs back to the source account. Works for iCloud, Google and Outlook.
ZefirCalendar spots Google Meet, Microsoft Teams and Zoom links inside the event and shows a join button. No more hunting for the address in the invite body.
Type a word and ZefirCalendar sweeps every connected account, three years back and two years ahead. Finding that one appointment stops being a dig.
Made for people who just want their agenda working — no complicated setup.
One-click install from the Microsoft Store. No admin password, and the app can start with Windows if you want.
On first run, Settings opens with a guided walkthrough to connect iCloud, Google Calendar, and Outlook. Signing in to Google and Outlook takes one click, in your own browser.
Your agenda appears next to the clock, just like Windows 10: month view or a list of your upcoming events.
Try it free for 7 days — no payment, no credit card. If you like it, subscribe: it costs less than a coffee a month.

And after the 7 days, if you don’t subscribe?
The app stays installed and keeps showing today’s events in the tray. On the other days you still see the colored bars, but the titles, the details, and creating or editing events are for subscribers.
In Brazil: R$ 7.95/month or R$ 79.95/year. Cancel anytime.
There is no cloud in the middle: the app connects directly to iCloud, Google, and Outlook using each service's official APIs, and keeps your credentials encrypted on your PC with Windows' native protection (DPAPI). Subscriptions are processed by the payment platform, so card details never pass through us. Read the privacy policy.
ZefirCalendar is a Windows 11 desktop app that shows your iCloud and Google Calendar events together in the system tray — one click from the clock, just like Windows 10 used to do. With your permission, it connects to your Google account to read your calendars and to create, edit, and delete the events you choose; changes sync straight to Google or iCloud. Your credentials stay encrypted on your PC and never pass through our servers.
With your permission, ZefirCalendar connects to your Microsoft account through the official Microsoft Graph API to read your calendars from Outlook and Microsoft 365 and to create, edit, and delete the events you choose. It works with personal accounts (Outlook.com, Hotmail, Live) and with work or school accounts. The app requests only the permissions needed for that, and you can revoke access at any time from your Microsoft account. Your credentials stay encrypted on your PC and never pass through our servers.
ZefirCalendar is built by one person: me, Diógenes, in Brazil. I built this app because I lived this problem every day. On one side, the iPhone with my family's appointments on iCloud. On the other, my work agenda on Google. And on Windows, where I spent the whole day, nothing that brought the two together. So I built what I had always looked for and never found: my whole life on a single screen, quick and easy to manage. If something doesn't work, I'm the one who answers: suporte@zefircalendar.com.br.
