Hate to break this to you but even a website that consists of nothing but HTML (no CSS/JS) is still an "app". It's still being executed in the runtime environment of your browser when you load it. Just because the website chose to limit it's use of the features to just one (HTML) doesn't mean it's not an app (when executed in a web browser). If you read that HTML in a text editor then yeah, that's not an app but if you're reading it in a web browser you're "running it".
