Heads Up is a native macOS menu-bar app that counts down to your next meeting and takes over your whole screen the moment it starts — so you're on the call on time, without watching the clock.
Heads Up lives where a Mac utility should — in your menu bar, quiet until it's needed. A ring fills as your next meeting approaches, and a click opens a native macOS menu with your day and a one-click Join button. It reads the calendars you already have in the macOS Calendar app: iCloud, Google, Outlook, and Exchange.
A quiet ring shows how long until your next meeting — one glance, no math, no switching to your calendar.
When the meeting begins, Heads Up takes over your entire screen — every monitor, if you like — until you join, snooze, or dismiss.
Detects Zoom, Google Meet, Microsoft Teams, and Webex links (plus generic links) in the invite and puts Join everywhere a reminder appears.
Choose which fire: 15, 10, 5, or 2 minutes before, and at start. It skips all-day events, declined invites, and "free" blocks.
Heads Up reads your calendar entirely on your Mac. There's no account, no sign-in, no tracking, and it makes no network requests of its own — the only time anything touches the network is your browser opening a meeting link when you click Join. Calendar access is read-only; it never changes your calendar.
A single $19.99 purchase on the Mac App Store — no subscription, no account, no upsells. Pay once, and it keeps you on time for as long as you use your Mac.
