As an aside: I do not like the idea behind the Hemingway app. Editing prose is not the same as debugging code. Removing adverbs will not make you a good writer.

As an aside: I do not like the idea behind the Hemingway app. Editing prose is not the same as debugging code. Removing adverbs will not make you a good writer. And the whole idea of having some bot making automated comments on my text as I write it sounds distracting at best. If you want to write better, write more. And let people read your writing. Hear what they have to say. Style handbooks like "Writing with Style" or "The Elements of Style" are great, but you should attempt to understand the reasons they behind their recommendations, not just use them as a mindless checklist. Craft your own voice.
