The mobile notebook is an application for recording nature observations from all species groups and from all over the world. In the application, you can mark observations on the map, in addition to which it uses GPS to keep track of the route you have traveled in the terrain and the time of observation. May attach photographs and other additional details to the findings. Finally, the application saves the findings to the Booklet service in the Species Information Center, where you can continue to edit and complete them and browse. The findings will be displayed on the Laji.fi portal. The application is developed by the Finnish Species Information Center.
