Neat detail on the iA blog (iA are the makers of iA Writer): When you scroll the page while reading an article, a small call-out tells you how much reading time is left – a subtle hat tip to the reading time feature in the app.

iA Writer is opinionated. It asserts that reading time is a more useful measurement than pages. Echoing that opinion with their blog is a charming detail and a clever bit of branding.
