Introducing Leafsnap

Now available in the iTunes App Store: http://itunes.apple.com/us/app/leafsnap/id430649829?mt=8

Note: iPad and Android versions to be released later this summer.

Leafsnap is a free electronic field guide for trees. It's available as an app for iPhone that helps you figure out what tree you're looking at. Just snap a photo of a leaf and Leafsnap will analyze the leaf to help you identify it correctly.

Leafsnap was developed by researchers from Columbia University, the University of Maryland and the Smithsonian Institution. In addition to leaf-shape recognition, it also has thousands of photos of several species of trees' flowers, fruit, bark and more. Test your knowledge by playing games included within the app or browse/share your collection at any time.

Understand your backyard, understand your world... with Leafsnap.

A production of Smithsonian Institution
Produced by Brian Ireley with Sarah Taylor
Starring Vivian Nweze

@Yowzoe you clearly have no background in biology whatsoever. no picking off one leaf of a tree will not do it any harm in the slightest. it would be a major evolutionary disadvantage if such an insignificant change had any sort of effect on a tree. im not sure if you realized this, but leaves grow back dipshit.there are many cases where cutting branches off a tree is beneficial for it. delete your comment, so weak minded people dont hold back on learning science with this app

Grab ahold of all those poison oak and poison ivy leaves friends!

Thanks to so many perverts misusing this app, the program now thinks there is a penis leaf.]

Keep in on Chat roulette you freaks.

@benchokwaiman that would be a nice feature being able to determine whether a plant is edible or poisnous if you are someone who goes on hikes and stuff in the forest and need to survive on leaves only.

She's a pretty girl, that said it would be nice to see an Android version sometime soon :) I wish I could have been a part of the development team lol.

No more wiping with poison ivy !!!!!

This app does NOT work. Don't get ittt

[savagecabage]

@ilovejaway @uggles2 ok thats obvious that picking one leaf off a tree isnt going to harm it, but what happens when a bus load of kids come along one day and they each do it, then the same thing the next day? and repeat .how long before the tree runs out of leafs?

you still need a book while walking

[MrTothCsaba]

I still say not to pick off the leaf if you can make a photo by avoiding it. This is a principle, it's not about if the tree can survive it or not. Don't change it if you don't have to.

damn... iPhone users don't hike in the woods sillypants, they use the subway. You should have made this for Android, since it has more users :)

Hoping this expands to Canada, I'm sure UofG can help with that!
