Active Knocker

The problem here is they don't even let you see the app or get a feel for whether you like it unless you pay over $100. I have no clue how they're getting clientele. Back when I used this a few years ago I could have sworn there was a free trial. It's a pretty bad look not to even let the person see the user interface before giving them a payment screen. That being said I do remember the app being decent when I used it so I will give this three stars.
