So whilst browsing through the overpriced COG games on the mobile market I came across a little gem that was free so yip-ee. called Seen.
Basically its a little love story through text messages where you can decide the story like any other CYOA. They even have a story editor to make your own whilst it's kind of hard as they give you no tutorial as far as I can see unless you go out looking for it.
Though if your looking for something to fun to do on Mobile I would check it out.
