National Geographic has a fantastic app that shows the construction of the Titanic over time. Building Titanic allows you to scroll across a timeline and view the different stages in which the Titanic were built. This app could be used to discuss timelines or analyze primary source documents (there are lots of photographs spread throughout the app).
