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.

Ratings and Reviews



Has the potential to be an awesome app.... But sadly hasn't worked since I downloaded it. The database is incredible and beautiful to 'leaf' through (please forgive the pun!). BUT... It crashes every time I take a picture (if not before) and the one and only time it did actually photograph a leaf it gave me about 35 possibles... And then crashed! So. First make it work. Second include English tree names. And then guess what? You could so easily charge for it! I'd pay good money if it worked! Keep it up people - this could be an a m a z i n g app!



I've been waiting for an app like this for ages but Leafsnap is almost useless. Uploads take ages on 3G and wifi, and the matches that come back (when the upload doesn't fail) appear to be random. I uploaded around 20 distinct leaf shapes on the requisite white background, on average got around 20 matches each back, and was none the wiser in terms of being able to identify the leaf. Given the marketing spiel on the website, I was very disappointed and would not trust this brand in the future


Not Reliable Ident Tool

A beautiful app, and the concept is great but as an Arboriculturist and dendrologist I can say with authority that some of the botanical names have been incorrectly given to certain sets of images. The images for Quercus robur is for example, completely incorrect!
