UPDATE - I realized I made a mistake when I originally uploaded my resume. I didn't include a job description, I uploaded a link only and it gave me a false low score. I didn't realize I changed it when I signed up. The tool is helpful in pointing out how to tweak your resume. Before I started I was a 60-70% match and after I was a 90%+ match with a few short tweaks. If you use it right, it will save you a lot of time.
