I do have a tiny web server installed on my development machine, so I mostly open the project on my iPhone over Wi-Fi using a local IP address. That way I can test my new features instantly, and verify that some bug has been fixed.
When you visit a touch-enabled web page that includes

The latest version of the code is always available in the GitHub repository.
