If you are out for a stroll and dont mind having to take out your device and interact with it every 7 minutes or so then this is the app for you. If you are trying to get a serious walk in, are walking in the rain or, in my case, walking in minus 30, then this level of interaction is annoying. After a minute in minus 30 your finger tips start to hurt.
Great story that will keep you amused while out for a leisurely stroll. Otherwise stick with Zombies Run.
