Meet Homo Heidelbergensis, follow the saber-toothed cat into the undergrowth, or see where the Rhine used to flow: all of this is possible with the "Weitersehen app", which invites you to explore the hidden parts of the Rhein-Neckar district. Users can use the app as part of a linked bike tour, make the invisible visible for themselves, but also actively immerse themselves in the nature and culture of the region. The innovative type of digital communication gives residents and guests of the region a deeper look at the natural and cultural landscape that surrounds the Rhein-Neckar district. The two tours "Ur-Neckar" and "Ur-Rhein" are available to start with.

With further tours, the range of offers for different groups is to be expanded noticeably. This creates a new tourist offer that makes the hidden or lost treasures in the Rhein-Neckar district visible to both locals and guests. To trigger the time travel stations, you first have to decide on a tour and are navigated directly to the first selected station. On site, the smartphone camera acts as a "magic magnifying glass" that allows users to discover things, solve puzzles and collect hidden items that remain invisible to the naked eye. At each station there is a marker that draws users' attention to the station.
