With citizen science technologies, citizens volunteer to help researchers with mapping out nature via data collection, such as the registration of plant or animal species. 



One of the most famous and most comprehensive citizen science apps is iNaturalist, a social network of scientists and regular citizens collaborating to map out biodiversity across the globe. With iNaturalist you can record observations of flora, fauna and fingi, get help with identification and participate in specific local projects focusing on certain species. You could also use the app to coordinate or join a local bioblitz ⁠— an event in which volunteers do an intensive area survey, trying to find and register as many species as possible within a limited amount of time. 

The app is available on App Store and Google Play. 


Some apps in this category focus on particular kinds of species or locations in nature. BirdNET, for example, specializes in bird identification by sound. As part of a research project about training artificial intelligence to classify bird species, the app allows users to submit recordings and review suggestions while learning more about the birds in their vicinity. The app is associated with the Cornell Lab or Ornithology, and the collected data has already been used to replicate findings in avian ecology. 

The app is available in App Store and Google Play. 


Mapillary was created to explore not plants or animals, but the landscape itself. By periodically taking pictures while you go on a walk, for example, the app uses computer vision to connect the images with 3D reconstruction and identify relevant markers, like road signs. This creates an interactive map with up-to-date features, similar to Google Maps. Mapillary maps and data are used for research and development purposes. The app is compatible with GoPro and can be used during bike and car rides as well — the possibilities are endless!

The app is available on App Store and Google Play. 


Citizen science apps are afford opportunities for a wide range of educational activites using available materials like smartphones. 

Organize a Bioblitz 
Using iNaturalist, or the more child-friendly verison, Seek by iNaturalist, you can organize bioblitz events for both younger and older children. Findings can be discussed and compared, and the activity is an excellent opportunity to introduce the concept of biodiversity in a hands-on way. For a more detailed guide to using Seek by iNaturalist for educational purposes, click here

Survey a Local Area
Survey a local area, both in terms of landscape and biodiversity. Constructing a cooperative Mapillary map with childen can prompt discussions about eco-friendly urban design (e.g. water drainage or green areas), while other registration apps like iNaturalist can help survey local species. Learn more about surveying activities by clicking here

Bird Days
Use apps like BirdNET to help identify birds by their song during a walk. Practice identifying the birds by appearance and sound, and dedicate special theme days to exploring facts and features of the relevant birds. Learn more about bird activities by clicking here

These technologies serve as reference works, providing helpful information about various natural phenomena even while you’re in nature. Some of them are digitized reference works which also can be found as books, while others offer completely new features that exceed a book's functionality by presenting the knowledge through other modalities. 


Stellarium Mobile

Stellarium Mobile is an app for the amateur astronomer, providing a virtual night sky with marked constellations, planets and much more. You can use it to plan observations, check visibility and get exact positions of celestial bodies, all tailored to your location. The app also allows you to explore different "sky cultures" and their conventions for naming constellations and planets — with everything from Romanian to Navajo settings. By upgrading the app for 19 kr. a month, you can access even more functionalities, but there is plenty you can do with the free version as well. 

Available on App Store and Google Play


LeafSnap is a plant identification and care app. You can either search plants by name to access detailed information and photos or use the image identification function to help you determine the plant species. Information about your region helps the app make more accurrate classifications, and if you decide to take a plant home or buy one, you will be able to find extensive information about care, watering schedules, diseases etc. 

Available on App Store and Google Play 


Reference apps can be used on their own, but are also especially good for combining with other types of activites and technologies. 

Take Nature Home 
In this activity, the participants choose a plant from the outdoors (always check endangered lists) and try to recreate its environment at home or in a classroom. Use LeafSnap and other reference works for information and care instructions. If the plant does not survive, try to identify what went wrong. 

Night Sky Experts
Explore the night sky with Stellarium Mobile, with or without a telescope. After a while, have everyone exit the app and check how many constellations they can remember and identify. 

These technologies focus on helping users identify edible plants and fungi on site, so that they can be taken home and prepared to eat. Foraging apps support skills that go beyond knowledge acquisition about natural phenomena, but include hands-on experience in local exploration and the use of all senses - including taste buds. 


Vild Mad (Wild Food)

This foraging app, now also available in English, will help you explore edible forageables in the Danish landscape. Save your favorite foraging spots as well as pictures and notes for reference.
