What, why and when
Species identification apps are used to easily and quickly identify species during field trips, mostly by beginners. They are also increasingly used for citizen science projects such as iNaturalist and Flora Incognita. In such projects, people interested in ecology and nature conservation can identify species using the app and also upload the picture and location of the observation. This is then checked by experts. Of all uploaded and checked photographs, a database of species observations is created. However, not all of the identification apps are directly connected to such a project. Most apps allow you to create your own library of species observations on your device.
Goals
Learning to identify species is hard and takes a long time. To easily identify species and enable people to get to know birds, plants, insects and other taxa, many apps for smartphones and tablets were developed in the last couple of years.
List of apps sorted by taxa
Most species identification apps work with photographs that are taken through the camera of the device and then uploaded and compared to a picture database. The species with the highest similarity to the uploaded photograph are then displayed, so that the user can select the most fitting alternative. Some apps do not take up any data input. In these cases, the app uses a species identification key or shows pictures that can be used for comparison. This is often the case for apps that are based on a book. In some cases, you can play a sound, e.g. of a bird, and compare it to the sound you heard on your field trip. Please be careful with this function as playing voices of animals in the wild can distract present animals. In Germany, this is even prohibited by law (§ 39 BNatSchG).
Please note: For many apps, there is a free version with the basic functions and you can buy more functions and species descriptions in the app. In this article, for free apps, only the version with the basic function is described. If you are interested in the app, please check out prices for additional functions in the app store.
Information about each app was retrieved from the respective app stores (Google Play Store, Apple App Store).

Picture search engines
Species identification is also possible by using the picture search function of search engines such as Google Lens. Here, you just have to take a picture with your smartphone or tablet. Then, you go to Google, select Google Lens and upload the picture. It is also possible to upload the picture with Google Lens. Similar pictures from the internet will be shown. For owners of an Apple device, this works in a similar way. In many cases, the results already include a species or genus name or at least a hint towards the taxonomic family. However, the result might not always be correct, especially on the species level. Distinctions between species that are closely related might not always be clear. The distinction on a species level therefore only works for species with very distinct characteristics.
iNaturalist and Seek - A citizen science example
The iNaturalist project began as a project by a Masters's student at UC Berkeley in 2008 and subsequently became an initiative supported by the California Academy of Sciences in collaboration with National Geographic. Since 2023 it is an independent non-profit organization that partners with a wide network of institutions (iNaturalist 2024 a, b). The iNaturalist community consists of hobby biologists and experts representing diverse levels of knowledge from all over the world. The majority of members use the app as ‘observers’ and upload their pictures and other data, while the ‘identifiers’ have curative functions of identifying observations or verifying identifications coming from the community. Community members with a certain number of certified identifications can be promoted to curators (iNaturalist 2024 c).
Figure 1. Map of species identifications (Feb 11th, 2024). Areas highlighted in red have the most identifications.
How iNaturalist works (from the App instructions):
- - Observe: Find a species and take a good picture for identification
- - Share: Upload the picture to the iNaturalist community and give details about the location, time and specific characteristics of the environment
- - Learn: The community can now join the discussion about identification of the species and make suggestions.
- - Citizen science: Observations are shared with a network of scientists who determine the quality of observation and identification and build a database for understanding patterns in nature and for protecting biodiversity.
