Stories seem okay but you have to pay to see pictures and read other stories? For the people that dont mind it i guess its okay but i can just go pick up a sci-fi thriller book and have a better time. The developers make themselves appear really greedy too when it is actually a pay to get scared kind of app. There should be some ads at the top or bottom of the screen for a free demo version and you get a new story every couple hours.
