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.

Mobiilivihko is an app for recording nature observations from all species groups and locations. The app allows you to mark observations on the map and it tracks the traveled path with the help of GPS, and saves the date and time. You can attach images and other details to the observations. The app saves the observations into FinBIF's Vihko service, where you can continue editing, filling and browsing them. The observations will be visible on the Laji.fi portal. The app is developed by the Finnish Biodiversity Info Faculty (FinBIF). NOTE: The app doesn't work on some iPhone models. If the app doesn't work for your phone, we'll be notified automatically. We'll publish an updated version as soon as the bug is fixed.
