Arter - Indberetning is a free Android app developed by Miljøstyrelsen Miljøministeriet in the Education & Reference category. It is designed to enable users to report sightings of species they come across in nature. The app is linked to the Danish database of species called Arter, which collects data from both private and public sources and makes it available to everyone.

The main functionalities of the app include logging in to your Arter profile, reporting sightings directly from your phone, and seeing sightings made by others in the vicinity. With the app, you can create a user profile on Arter.dk and link your reported sightings to it. You can also download offline maps for use in areas without internet connectivity. However, for a more detailed picture of the species, you will have to visit Arter.dk as the app is a simple tool designed for use in the field.

It is worth noting that when you report a sighting on Arter, your data becomes publicly available for both commercial and non-commercial purposes, as long as the source is clearly indicated by your username and Arter, and it is used in accordance with Arter's purpose. Your pictures cannot be used for commercial purposes but can be used for non-commercial purposes under the same conditions as other data.
