After not even ONE try, it asks for Pro. No success, just imo developer hyper-greed. Avoid!

Wow is all I can really think. I am literally at a loss for praiseworthy words. Context Minds has truly set the bar and blown me away. There is nothing that I can think of that would improve it. It is awesome and so user-friendly. It really is everything you could want in such an app. Good jobs guys!!!
