I was on the search for a simple doorbell QR code app and this fits the bill perfectly! It functions well, is easy to set up, and the customer service is amazing- so quick to respond and so helpful!

I built an app to use a QR code as my doorbell2024 · dingdongdoorbell.com · ▲140I 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…


Scan QR codes to check in guests registered via Google Forms2023 · workspace.google.com · ▲115Hi HN! I made a no-code platform for creating physical data collection apps, using QR codes [1]. It does not yet have a self-service config UI though, which limits adoption. That's why I recently released a Google Forms™ add-on for QR code check-in, based on the platform. This focused use-case makes it easy to provide a fully self-service config UI. How it works: 1. Create your Google Form as you normally would [2] 2. Activate the add-on if you hadn't already [3] 3. Craft a confirmation email to be sent to each form responder Upon each form submission, the add-on will send a PDF with a…

Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
