The multi-platform HoneyDo List application starts with the web. This version of the application, hosted on App Harbor, let’s you share lists between devices using your phone’s camera. Create a list in your browser, then share it via QR code with your phone. The lists will be kept in sync. Here’s a demo.
My next step is to get the Windows Phone companion app reading these QR codes and sharing lists. Once that’s submitted to the Marketplace, I’ll start working on the Windows 8 app.
