NEW COST: $2.99. (It used to be $0.99). It works fine without paying. "In-App Purchase Benefits: • Remove the app name from the window title for a cleaner look. • Enjoy an uninterrupted experience with no nag screens. • Hide the purchase icon for a sleeker interface." But it's worth the price as basically shareware. - - HOWEVER! Completely setting it us is an elaborate chore! No doubt the few 1-star ratings are from people who gave up. But IT WORKS! Click the HELP inside the app Preferences and READ. But BETTER YET: Go to the Dev webpage and scroll down to the VIDEO "Setup Screen Mirror". This will walk you through the entire, lengthy, rather PITA process of setting up ALL of the functions. Again, IT WORKS! But you have to finish the entire, lengthy, rather PITA process to GET it to work. You're going to learn some things about your iOS device you never knew or believed possible. IT'S A LEARNING CURVE. But it's worth it! 😄
