Apportable using GNUstep to port applications from iOS to Android

I just found out about a company which is using GNUstep to port applications from iOS to Android.   There website is here.   They list GNUstep as one of the projects they are using here.   Upon further discussions with them they are using GNUstep Foundation very heavily with other parts of GNUstep in other places.

I have to say I didn't expect this, but it is an awesome thing to see!
