About

DOQR

Features
Read full description

DOQR is a QR-based digital doorbell that does not connect to an electronic doorbell or external accessory. There is no Bluetooth, Wi-Fi, NFC, or other hardware pairing. DOQR is not a companion app for a physical smart doorbell. Create a door-specific QR code in the app, print it on paper or a label, and place it where visitors can see it. A visitor scans the printed QR code with any phone camera and rings through the web without installing an app. The DOQR host app notifies you instantly so you can respond by text, audio, or video. HOW IT WORKS 1. Create your digital doorbell in the DOQR app. 2. Print the QR code generated by the app and place it at your door. 3. A visitor scans the QR code with any phone camera and rings from the web page. 4. Open the notification in the DOQR host app and respond to the visitor. There is no electronic device to buy, power, install, or pair with the app. The only physical item at the door is the printed QR code generated by DOQR. KEY FEATURES • A permanent QR code for each digital doorbell • Instant visitor and ring notifications • No app required for visitors • Text conversations • Device- or network-level visitor blocking • Permanent account and data deletion inside the app FREE PLAN • 1 digital doorbell and 1 host • Unlimited ring notifications and text conversations • Your 3 most recent visits DOQR PRO • 3 digital doorbells and up to 3 hosts per doorbell • 90-day visit history • Audio and video calls • Courier notes and delivery code • 120 audio minutes and 60 video minutes per month under the fair-use allowance DOQR Pro Annual is an auto-renewable subscription. The App Store shows the current price in your local currency before purchase. You can manage or cancel the subscription from your Apple Account subscriptions and restore purchases inside DOQR.
