Partners, housemates and kids can’t see your calendar. Callsign reads it for you and puts a busy sign on your phone, on your desk or by the door, so nobody walks in on your meeting.
Any event with a video link puts up the sign. Fifteen minutes before the end it turns amber. When it’s over it says come in, and lists who knocked while you were busy.
One is free, Pro unlocks six more, and the rest come in packs of four or five. Every one of them animates through the meeting. These four are running live: one meeting, played in 30 seconds.
Add the free Mac menu-bar app and the phone controls your Zoom, Meet or Teams call. In laptop mode the buttons sit on the flat half, next to your keyboard.
