Easily message your neighbors

Knock is the messaging app for building residents. It's the easiest way for neighbors to have group or private conversations on their phones. Knock is great for sharing utilities, subscribing to security and maintenance notifications, or even doing fun things like coordinating meetups and getting to know your neighbors better. We’re slowly rolling out to properties in San Francisco and NYC.
