Only used it twice but impressed with ease of use and initial results. And free on top of it? Definitely 5 stars for the current version. EDITED TO ADD: Recently, this app changed to a pay model that now prevents you from using the app in any way. I'm noylt against paying for good software, but this suddenly becamr so obnoxious that I have to assume the app was sold to another entity that have now ruined the app. So, I will no longer be using this app.
