Notifications are easy to miss.
This isn't.

DoNotMissIt sits in your Mac's menu bar. Shortly before each meeting, it covers every display with a card showing the meeting and a live countdown. Press Return to join the call, or Esc to dismiss.

From the menu bar to the meeting

It stays out of the way until it matters, then makes sure you can't look past it.

  1. 8m

    The Mac menu bar showing Daily Standup · 8m, open to a list of today's meetings from 9:00 Daily Standup to 17:30 Gym.

    In the menu bar

    Your next meeting and the time until it starts. Click it to see what's coming up, and choose one to preview its alert.

  2. 0:42

    The alert for Q4 Roadmap Review, 10:30 to 11:30, with a Join Google Meet button and an orange ring showing 0:42 until start.

    On every screen

    Shortly before the start, a card covers every display. It finds the join link in the event's URL, location or notes, so Return takes you straight into the call.

  3. +0:27

    The alert for Customer Call: Northwind after it has started, with a red ring showing +0:27 since start and a Join Teams button.

    Running late

    Once the start time has passed, the ring turns red and counts up, so you know exactly how late you are.

The details

It reads the calendars already on your Mac, so iCloud, Google, Exchange and any other account you've added in System Settings all work.

Private

The app has no analytics, no advertising and no accounts. It doesn't collect, store or transmit any personal data, and it runs in Apple's App Sandbox with no permission to use the network.

Open source

The code is public under the MIT licence, so you can check that for yourself, or build it from source.

This is a preview, so Join won't open anything. In the app, Return joins the call and Esc dismisses.
