By Columbia University, University of Maryland, and Smithsonian Institution

This app is only available on the App Store for iOS devices.


Leafsnap is the first in a series of electronic field guides being developed by researchers from Columbia University, the University of Maryland, and the Smithsonian Institution. This free mobile app uses visual recognition software to help identify tree species from photographs of their leaves.

Leafsnap contains beautiful high-resolution images of leaves, flowers, fruits, petioles, seeds, and bark to aid identification. These high-resolution images were created by the conservation organization Finding Species.

Leafsnap currently includes trees found in the Northeastern United States and Canada. The inclusion of Canadian trees is through collaboration with the Canadian Wildlife Federation, with support from TD Friends of the Environment Foundation.

What's New in Version 1.08

Leafsnap now works for iPhone 7. You can also now browse species without being connected to a Wi-fi network.

Great idea, but problems with the app

I just downloaded the app from the US iTunes Store and tried to create an account but failed. I also can't choose my location because my location (Germany) isn't one of the options. Not sure if that is why I can't create an account but I'm disappointed I can only use this for scrolling through the built-in pictures. Please consider an option for other locations. There are lots of trees here that can be found in the US that I would like help identifying.

Upgrade includes new species and works great!

I just downloaded it and it has more species than before. This version has fixed all previous bugs and I was able to take pics and recognize leaves I found outside. Thanks!

Impossible to say

Over the space of three years I have attempted to download and utilize this app. Needless to say this has been tried using several updates of Apple's OS and not once has it worked for me. The app is huge. It requires that I remove part of the tree or carry around a white background with me. Paying for an app does not always indicate it's value, but in this case I have gotten what I paid for. What a shame.
