I put together a quick website that I thought the community might find interesting. Basically, it uses the public API of a ghost website to show statistics about number of posts, words per post, and a few other stats.

It’s a proof-of-concept at this point. The public API is deprecated and will probably go away soon, so I’m thinking about options for connecting the site as a custom integration.
You will probably need to change some code on your app at some point because Public API is deprecated. You will need to use Ghost’s Content API. Users will need to somehow comunicate between their blog and your app with an integration. Ghost API Versioning.
