I saw this program on StumbleUpon and it only costs $9.99 so I decided to give it a try. I will let you know as I use it, but so far it looks like it will improve my edits. It automatically color highlights your work a lot like my beta readers do. Here is a sample from the StumbleUpon post for the Hemingway Editor 2.0, found at hemingwayapp.com.
Hemingway App makes your writing bold and clear.
The app highlights long, complex sentences and common errors; if you see a yellow sentence, shorten or split it. If you see a red highlight, your sentence is so dense and complicated that your readers will get lost trying to follow its meandering, splitting logic — try editing this sentence to remove the red.
You can utilize a shorter word in place of a purple one. Mouse over it for hints.
Adverbs are helpfully shown in blue. Get rid of them and pick verbs with force instead.
Phrases in green have been marked to show passive voice.
You can format your text with the toolbar.
Paste in something you’re working on and edit away. Or, click the Write button to compose something new.

You drop your Word file into plain text, then open. When you are done, you can reverse the process. I dropped one of my upcoming books into it and I have already found some very helpful edits as a result.

Thanks for sharing this editing software, Mike. I’ll try it. Have been using WritersDiet.com which has a similar focus, but is limited to 1,000 words. This process also color codes items worthy of attention. The experience instilled awareness for improved ways to write the first time, and saved immeasurable time.

This one did 100,000 words in 5 seconds, so I figured I would give it a go.
