Description

Callsign turns your iPhone into a sign that tells the room when you're on a call, so people know when to come in and when to wait. It reads your calendar. When a meeting starts, the sign goes up; when it ends, it says you're free. No buttons to press, nothing to remember. MADE FOR IPHONE DUO Fold your Duo into a tent and the sign faces the room on the outer display. Fold it to 90° like a laptop and the sign stands on the top half, with the time left and your call controls below. On any other iPhone, stand it on your desk and put the sign up full screen. SIGNS FOR EVERY MOOD Start free with Classic: green when you're free, red when you're busy, with the time you'll be back. Callsign Pro adds a countdown, a loading bar, a traffic light, neon, a pixel-art mountain sunset and more. Sign packs add the fun ones: Breakout and Pong that play out over your meeting, a bouncing DVD-style sign, a microwave that dings when you're free, a lava lamp and plenty more. CALL CONTROLS With Callsign Pro and Callsign for Mac, mute, turn your camera off, raise your hand or leave the call from your phone. Works with Zoom, Google Meet and Microsoft Teams. MAKE IT YOURS Customize the words, colors and fonts on any sign you own. Let Random pick a different sign for each call. Use all your calendars at once. KIND TO YOUR SCREEN Minimal versions of every sign draw thin lines on pure black, so most of the screen stays dark. A screen saver and a slow drift keep the words from burning in. PRIVATE Callsign reads your calendar on your iPhone. Your events aren't uploaded anywhere. PAY ONCE Callsign Pro and each sign pack are one-time purchases. No subscription.
