The next meeting sits at the top with its Join button, so you can hop in early.

Questions
Which calendars does it work with?
On a Mac: Google Calendar directly, including Google Workspace, and every calendar in the Mac's Calendar app: iCloud, Microsoft 365 and Exchange, Outlook.com, Yahoo, Fastmail and any CalDAV account you've added in System Settings → Internet Accounts. On Windows: Outlook, Microsoft 365, Exchange Online and Outlook.com through a Microsoft sign-in, and Google Calendar. Add as many accounts as you like; a meeting that shows up in two places is only shown once.
Does it work with Outlook and Microsoft Teams?
Yes. On Windows you sign in with your Microsoft account directly: Microsoft 365, Outlook.com or Exchange Online. On a Mac it goes through the Calendar app: add your Microsoft account in System Settings → Internet Accounts, then turn on the Calendar app in MeetingWarning's Settings; a direct Outlook sign-in on the Mac, for companies that block Internet Accounts, is planned. Teams links in invites open with one click.
Is there a Windows version?
Yes. MeetingWarning for Windows does the same job: the full-screen alert on every display, Enter to join, the same rules, and today's and tomorrow's meetings in the tray. It signs in to Outlook, Microsoft 365 or Google directly. It's coming to the Microsoft Store for $5.99 once and needs Windows 10 (version 2004) or Windows 11.
Does it work with several screens?
Yes. The alert covers every connected display, and Join and Dismiss work from the main one.
What if I'm presenting or in a full-screen app?
It still appears, because that's the point. If you don't want it for a while, pause it from the menu bar (Mac) or the tray (Windows) for an hour or for the rest of the day.
Can I choose which meetings take over my screen?
Yes. The menu bar (Mac) or the tray (Windows) shows today's and tomorrow's meetings, each marked as will or won't alert, with the reason. Skip a single meeting, mute a repeating one, or choose Alert me anyway for one your rules would skip. Meetings without a call link, meetings you declined, focus time, out of office and all-day events are skipped by default.
Can I choose how early it shows up?
Yes: when the meeting starts, 30 seconds, 1, 2, 5 or 10 minutes before, or any custom time up to an hour.
Does MeetingWarning see what's in my meetings?
It reads the title, time, location, your response, who's invited, the notes and the call link, so it can decide whether to show the alert, open the right call and show the meeting's details when you ask. That stays on your computer and is never sent to us or anyone else. Calendar access is read-only.
How much does it cost?
$5.99 once, with updates included: on the Mac App Store for macOS 14 Sonoma or later, and on the Microsoft Store for Windows 10 (version 2004) or Windows 11. No subscription, no account. Each store sells its own version, so Mac and Windows are separate purchases.
