From ATS Heritage:
Talking Guides Downloader is a family of Apps designed to allow visitors to Cultural Sites such as Museums, Castles, Cathedral and Art Galleries to receive interactive multimedia tours. Normally each site will have its own App or collection of Apps with versions for languages. This generic Talking Guide Downloader is an innovative way for Talking Guide clients to download their content onto their iPhones/iPods. It also allows the user to load some smaller and temporary tours which will change on a more regular basis.
