Are you the vendor of the iToy exam 'app', or what?
Not at all, in fact I have never seen any of the PPL exam iphone APPS, and I don't even own an iphone! I certainly wouldn't know how to create an iphone APP of any kind.
I can understand why you don't like them, and personally I have never liked any product that does not include meaningful explanations. Whether or not the "iToys" have such explanations I do not know. As I said I have never seen any of them.
But your apocalyptic posts concerning impending changes to the PPL exam system would be much more credible if you made them more realistic.
