    I built an app to use a QR code as my doorbell▲140

    I didn’t have a doorbell before (multiple reasons) and my house feels unwelcoming without one. So I built a doorbell app that uses a QR code - visitors scan the QR code to ring the doorbell and I get notified on my phone. Here is an example of the QR code I have on my door. You can scan it and say hello: https://www.thebacklog.net/img/2024/10/show-hn.png This was also a great excuse to build my first app for Android and iPhone. I’d love to get some feedback before I spend more time polishing the app. Please try it out and feel free to ask me any questions! No…
