Plus one that’s on your computer
You can also test readability through Microsoft Word’s readability statistics.
PC users: Go to Tools > Options > Spelling and Grammar > Click “Show readability statistics” box.
Mac users: Go to Word > Preferences > Spelling and Grammar > Click “Show readability statistics” box.
Once you’ve turned it on, every time you run spelling and grammar check, you’ll get a box with lots of information about your copy.
Caveat: In older versions of Office, the Flesch Reading Ease formula doesn’t report scores lower than zero, and the Flesch-Kincaid grade level doesn’t report scores higher than 12. With Office 2003, Microsoft fixed the grade level formula but not the reading ease formula.
Both remain defective in Mac versions of the software.

The best tool I’ve found for readability analysis has some free stuff and some paid stuff – readable.com
I like it too. I have questioned its metrics in the past, but they seem to have gotten a handle on that. I also like the extra tools, like Thin Post checker and the readability by sentence checker.
