This is just another case of a dishonest developer making a fraudulent claim. The "free" download of the computer version of Quick Voice is completely incompatible with any OS I am aware of. Apple really should DO SOMETHING about this sort of blatant fraud. DO NOT purchase or attempt to download anything related to this developer. The good reviews are ringers.
You have been appropriately warned.
Very best to all (except the developer).
