There is no one-size-fits-all answer to this question, as the best blog app for a certain person or business may vary depending on their needs. However, some popular blog apps include Blogger, WordPress, Medium, and Tumblr.
When choosing a blog app, it is important to consider what you need the app for. For example, if you are primarily a writer and don’t need a lot of features or functionality beyond creating and managing your blog posts, then Blogger may be a good option.
Conversely, if you need more features and functionality than Blogger offers (e.g. the ability to add photos and videos to your posts), then WordPress may be a better option.
Ultimately, the best blog app for you will depend on your individual needs and preferences. If you are not sure which app would be best for you, it is recommended that you try out several different options to see which one best suits your needs.
