With Observation you can easily record nature observations in the field. Our online image recognition AI helps you identify the species on your images. You can choose to use the app offline anywhere in the world. Your observation data is stored on your phone first. Saved observations can be uploaded to Observation.org when online. This app is part of Observation.org; an EU-based platform for world wide biodiversity monitoring and citizen science. Observations that you save in your account are publicly visible for everyone who visits Observation.org. Take a look at the website to see what other observers have recorded and explore all data collected by our community. Observations are validated by species experts, after which the records are made available for scientific research.
