The idea with the app is to save your life bird sightings in a list. You can have an arbitrary number of lists. One observation per bird is allowed in one list. The app also calculates a list with lifers. The life list compiles a list of all unique observations from all your private lists with statistics of number of unique sightings versus the total number of birds.

Taxonomy: The app uses Bird Life Sweden list for supported birds in Sweden from 2024. You can add own species in the app if they are missing in the list.

Share your observations: All lists can be exported. The lists can be exported so you can share with yourself or with others.

Import Bird Sightings: You can import Bird Sightings via a comma separated file. There is a help section for the format in the Import menu.

Group observations: Group observations are also supported. The idea is to register all observations for a specific Bird Sighting group. Group observations are not included in the life list and thus there is no life list for these observations.

Safe store of observations: All observations are safe stored in a database and will be kept there until you uninstall the app.
