I can not understand why so mercilessly 1-star reviews are completed here. The app does exactly what it says in the description! If you do not care, then load the App Just not down, no one is forcing you but more on that! Since I'm a developer, I know how frustrating it is when you get bad reviews because users bemägeln in the app something you've never promised. Granted, I find this app also not interesting and have it just me downloaded to be able to post a comment, but the app provides exactly what is in the description, therefore it can only get 5 stars because the simulation is implemented well. And just because my interests are not represented it is not a bad app ... people, once your brain turns yet.
