Qoorbell: the video doorbell that is a QR code
Qoorbell is a project we built for a client. We designed and built all of it: the website, the web app, the Android and iOS apps, the backend, payments and the admin console.
- Web, Android and iOS
- Available in 60 languages
- Designed and built end to end
The product
A doorbell with no hardware
Qoorbell turns a printed QR code into a video doorbell. There is no wiring, no batteries and no Wi-Fi at the door, and visitors don’t install anything.
Print your QR
Create a doorbell in the app, like Front Door or Apt 3B, and print its QR poster for the door, the gate or the counter.
Visitors scan it
With their phone camera and no app to download, they open the doorbell’s page and tap to ring.
Answer from anywhere
Your phone rings right away and you answer by video call or chat. Visitors only see the doorbell’s name, never your name or number.
It works for houses, apartments, offices, businesses, rentals, front desks, deliveries, vehicles, pets and items, and for whole buildings with a single QR at the entrance.
What we built

We designed and coded every piece of Qoorbell for the client, from the page a visitor sees to the internal console.
