The first time you take a photo, it automatically creates an account for you, after which you can go to the options screen and change your username and/or password.

We have one under development, but since the app is free and the work is being done by volunteers, we do not have a release date, nor a firm guess as to when this will be.

Click the "Snap it!" tab. From there, you will be directed to a camera screen where you can then take a photo of a leaf on a white background or choose one from your phone's photo album. After submitting a leaf, the app will automatically add it to your collection and compute a list of potential species matches.

You must submit a photo of a single leaf on a fully-white background for our automatic algorithms to find them. If you are still having trouble, please email the photo and the error to support@leafsnap.com.

Simply swipe left on the row in the list of results to label your leaf as that species.

In the browse tab, tap "My Collection" at the top of the page. From there, simply swipe left on the row you would like to delete.

The Smithsonian was instrumental in collecting the datasets of leaf species and supervising the curation efforts throughout the course of the project. As part of this effort, the Smithsonian contracted the not-for-profit nature photography group Finding Species, which collected and photographed the high-quality photos available in the apps and the website.

Leafsnap currently includes all 220 tree species found in the Norheaster United States in Canada.
