Description by MAZARI HOLDINGS LLC (from the App Store)

KNOC is a simple QR doorbell for homes, offices, rentals, studios, and small spaces.

Create a door, print or share its QR code, and let visitors leave a knock without installing an app. Owners can receive visitor messages, view door activity, and reply from the KNOC app.

KNOC is built for simple, practical door communication:

• Create a QR doorbell for a real door or location
• Let visitors scan and leave a message without an account
• Receive knocks from visitors when they arrive
• Reply to visitors from your phone
• Use text, photos, or audio when available
• Manage your doors and account in one place

KNOC does not require special doorbell hardware. It is designed for people who want a lightweight way to know who came by and respond without installing cameras, wiring devices, or asking visitors to download an app.
