The Explore 9/11 app is a guide to understanding the 9/11 Memorial and Museum, the World Trade Center site and the history of 9/11.
It is designed to be experienced while visiting at the Memorial and Museum or anywhere in the world.
The app's primary features are map and story modes. Rotate the device to switch between modes. Users can explore a content-rich landscape of the memorial and multi-level maps inside the museum. Clickable hotspots along the maps reveal photos, videos, audio and more. In story mode, users can explore this content organized in chapters.
The app also features a new tribute mode where users can leave tribute messages, including their name and where they are from. Tributes can also remain anonymous.
