The default way to use PictureThis is by using your device's camera directly through the app. That said, you can also import any image you have on your device and crop it manually.
Another interesting feature in PictureThis is its user community. You can take a look at the most recent photos of plants uploaded by other users from around the world. And you can even see the map of your region to know where you can find different types of plants. This way, for example, you can find out if there are palm trees, roses, tulips, eucalyptus trees, etc. in your area.
PictureThis is a very useful app that lets you identify any plant, flower, or tree, in a matter of seconds. Plus, you can share your findings with the entire world.
