Diamond Head and Ghostfreak

How do you unlock diamond head and ghostfreak? Before telling me to look at the riddle, I did. It isn't a riddle it's just a cryptic message with no answer to it. I understand they're supposed to be hard to get, but after purchasing the app it's frustrating to still have gatekept information on it's features. If someone could please just DM me on how to do so, that'd be really appreciated.
