iPhone Screenshots


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

Version 1.08

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

This app deserves a 5 star rating. I am not sure why other people didn’t love it as much as I do. I used this to identify a tree in my yard. This app shows actual photos of all of the possible foliage that a particular tree species produces. Based on the snap I took the app provided my with several choices, but I was able to determine the exact one because of the additional photos. I will keep this app and use it whenever I wonder about a tree in the future.

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.

Not accurate


I ‘d love it if it worked, but it didn’t.
Some problems
1. The matches that came back are wildly different in leaf size! Yeah maybe the shape and color are somewhat close, but the first match has leaves 20-30 cm and the 3rd match has leaves 1.5 - 3 cm long!
2. Attention to leaf detail was not great. The vein structure, the length to width proportion, pointed or rounded.
Pretty much a flop.
