Now I know, most of might think that the concept to a paper keyboard is pretty good. To be honest, it is and that is why it got that one star. The reason why it didnt get the other 4 stars is because it is not user friendly, the paid features dont really work properly, calibration takes time and even after that the keyboard does not work properly and also, theres only one design for the keyboard. 3 dollars for this app is not worth the money. By the way, the paid features are unlimited writing, google talk , facebook chat and theres one more messenger that I havent heard of. Facebook chat says connecting but nothing shows up. Google wont allow the app to use google chat because of weak security. And the problem with unlimited writing is that when you type some letters, the letters above them is imputed. So, dont spend you money on this app. Well, not right now.
