Blogger

Blogger is a well-known blogging platform that allows users to create and publish posts. The app description explicitly mentions composing and editing posts, embedding images, and adding labels (tags), which aligns with a rich text editor and tagging system. It also supports user profiles and the ability to switch between blogs. As an app, it inherently provides mobile access. While it doesn't explicitly detail a recommendation engine or monetization model like Medium, it serves the core function of content creation and distribution, making it a strong partial match.
