Apple’s shut down its Watch Walkie-Talkie app after somebody reported a bug that could have allowed an eavesdropper to surreptitiously listen in on somebody else’s iPhone, the company told Tech Crunch on Wednesday evening.

The app works like, well, a walkie-talkie. You can list yourself as available to chat, and then you can hold down the Talk button on your Apple Watch while you issue important voice messages to friends of your choosing, like, “Whoa, check out the snow storm! Got lift tickets, you up for it?”

Release the button, and if your friend was available and up for it, you’ll hear their voice immediately as they respond with a hearty “Hey-ho, a-skiing we will go!”
