Before you pop that berry into your mouth, you might wanna check to find out if it's poisonous.
The handy app, Leafsnap, can help you do that.
After you download and install the free app unto your iPhone or iPad, you can search an extensive photo collection of leaves, flowers, and fruit to learn more about a specific tree or perhaps you encounter an unknown species in the wild, snap a photo and submit it for identification.
Right now, the database is limited but is expected to expand to cover the entire Continental U.S.
There are several good apps out there for researching bird species but I like Peterson Birds of North America.
This iPhone and iPad app gives you access to its database of over 800 species of birds on this continent.
Budding ornithologists will enjoy the beautiful color illustrations while uploading their own photos or locally-found birds.
Between these two apps, spending time outside got a lot more interesting and techy.
