Both the Apple Watch and iPhone support silent mode – a feature that mutes all incoming notification sounds to prevent awkward situations in certain predicaments, such as a ringtone going off in the middle of class or disturbing participants during a work conference. Unfortunately, this handy feature doesn’t stay in sync between both devices, necessitating manual input for each.
This is a problem that a newly released jailbreak tweak called WatchMuteMirror by iOS developer Cardboard Face aims to resolve. As you may have inferred already from the tweak’s name, WatchMuteMirror keeps silent mode in sync between your iPhone and your Apple Watch so that the latter doesn’t make a bunch of noise even after you toggle the mute switch on the side of your iPhone.
