The app has brought a new concept for taking your mind away from running and focus on the story. Concept wise it is good, it plays a story and and in the story you start to run slowly,pick pace a little and then run like hell and then again slow down a bit. The soundtrack is good like real blockbuster. It does tell you when to change the pace,but the story does not hold for long. You tend to get bored. The soundtrack though being of good quality does not bring in the desired effect. There are two stories on free version and others you can buy for $4.99. The stories are in two languages, English and Korean. I liked the Korean version though it’s same but the girls talking in Korean sounded much more real and in the story. I downloaded it because I like the concept of listening to blockbuster sounds and being a part of story but the free versions where not to my taste.
