Sorry, I haven't purchased the full version yet.
I tried the trial ver, I thought it is not a good port. Maybe developers just put files into Apache Cordova and output an App, it has not been re-adapted as an App.
First, the resolution remains 16:9, which is incompatible with screen which is 2K resolution, so black borders on left and right. And there are also left useless buttons for adjusting the resolution in the PC ver.
Second, slow response, it takes several seconds to change after clicked zoom button.
Even some basic functions are not working properly. UI cannot change some text size, and the exit button is not working, I have to swipe up to kill the App.
