Great App!
I love walking tours of cities and there are lots of phone apps that will help you get around. This one has a different twist as it covers how city are engineered. In New Zealand that means dealing with earthquakes. In Christchurch I did the complete tour which covers how old buildings were rebuilt and new ones constructed. Christchurch had two devastating earthquakes in 2010 and 2011. This allowed them to redesign their city, saving what they could and adding more green space where structures used to be. This app shows that process off is an easily consumed manor with plenty of was to get additional information if you want it.
