iNaturalist is a community website for sharing pictures and observations of plants and animals. To enable easy sharing of observations, iNaturalist offers a free Android app and a free iOS app. Using the apps you can take a picture, geo-locate it, write your observations, and upload to the iNaturalist community. If your observation is incomplete, for example if you're not sure of a scientific name, you can ask the community to add comments to improve the recording of your observation.
If you don't want to join the iNaturalist community, you can simply explore members' observations through the iNaturalist Google Map.
