Smartphone Apps can add a great deal to your time spent in nature, allowing you to better identify the flora and fauna around you.
While the Greenbelt staff uses many of these apps, we have not personally tested all on the list. However, all are rated 4-Stars or higher. Some may have only Apple or Android versions, most have both. Note that the text is taken from the designers' online descriptions, and is not endorsed by Greenbelt.
Many Apps are free, but some Apps may require in-app purchases to make them fully functional.
Some may require an internet connection (while you are deep in the woods), others may not.
If we’re missing an App that you would like to recommend to the Greenbelt community, please email Alexandra Letizia: firstname.lastname@example.org. Have fun out there!

Or, you can choose the Nearby Species feature to see what, if any, tree species have been identified by another Leafsnap user in your region. The Collection feature is where you can place photos of leaves, flowers, or fruit that you have taken with your mobile device and you can take those photos using the Snap It feature. Once you've taken a picture, Leafsnap instantly searches a library of images put together by the Smithsonian Institution. It returns a possible species name, high-resolution photographs, and information on the tree's flowers, fruit, seeds, and bark.

Pl@ntNet can also identify a large number of cultivated plants (in parks and gardens) but this is not its primary purpose. At present Pl@ntNet makes it possible to recognize about 20,000 species, a long way from the 360,000 species living on earth.
