Thank you for the support and kind words.

Regarding the iOS... I sincerely hope there will be an iOS version available somewhere in the near future. That is the plan, but... As I am a single developer of GUI-O application as well as GUI-O designer (not to mention all of the website content, etc.) and doing all this in my free time, it will probably take some time. Honestly, I cannot give you even the rough timing estimate.

There are some challenges "porting" GUI-O application to iOS.

Since majority of the application is written in C++ (I believe that clang compiler for iOS allows mixing C++ and Objective-C), this would be the "easier" part. There is some Android Java code which would need to be re-implemented.

But, as I see it, the most difficult part is the setting up the development environment. Installing Xcode on a non Apple PC is a pain. I believe newer Xcode versions don't even work with older Mac's, and buying a Mac computer costs a small fortune. I have tried running Xcode on a virtual Mac OS with unsatisfying results.

I apologize I cannot give you a better answer at this moment.
