In recent times, the knowledge of citizens about species is decreasing more and more. Filling up these gaps in knowledge is very important to raise the awareness for biodiversity, to increase acceptance, and to advertise ecosystem services. As modern mobile devices (smartphones and tablets) are broadly used by people, the project anymals.org (www.anymals.org) uses this technology in a citizen science project to create an interface between laymen, scientists and digitally available biodiversity information. With the help of the mobile software anymals+plants users can retrieve information about biodiversity in their surrounding and furthermore they can record own observations and measurements. Scientists and other citizen science projects can use the application as a generic tool for capturing data and encouraging people to join their activities. The general aims of the mobile app are not to create a new biodiversity database, but to combine multiple facilities and services to both inspire people to discover biodiversity in the field with the help of modern technology and to provide mobile software for research.
