With the Chirping guide, the user learns to recognize the sounds of Finnish grasshoppers and bushcrickets. The sounds are recorded by non-fiction writer Sami Karjalainen, and most of the information content in the application also comes from him. Habitat, distribution and a detailed description of the vocalization is covered from each species.
The application also shows the latest species sightings reported from Finland. The data comes from the Finnish Biodiversity Information Facility.
