I'd recommend Gatsby and use their PWA plugin. With a PWA you don't have to deal with the app stores, get better SEO, etc. Here is a starter package that offers quite a bit. It obviously includes all of the optimizations and performance wins that Gatsby is known for, but also includes support for creating your blogs with Markdown and since it's just a web app you could do most (if not all) of your animations in pure CSS or grab a library like Lottie to help.
