Not all nature enthusiasts are technology averse. In fact, many, like me, are using technology to enhance their connection with nature and live greener lives. Mobile devices have made it easier than ever to get the information we need when we need it to make greener choices on the go.

Check out the following list of some of my favorite (mostly free) green apps: 

The Dirty Dozen  
From the Environmental Working Group, this app is your go-to-guide when shopping for produce. Buying organic can mean a big hit to the wallet. But even experts agree that eating non-organic fruits and vegetables is better than not eating any at all. The good news is that buying organic matters more with some foods than with others. This app helps you make smart shopping choices by listing the dirty dozen, the 12 foods that it is most important to buy organic because they have the most pesticide residues.

BeeSmart™ Pollinator Gardener 
Planting pollinator gardens with native species is becoming increasingly important in sustaining healthy eco-systems and wildlife friendly habitats. This app by the Pollinator Partnership and Catch is a handy guide for selecting plants for pollinators that are specific to your area. Enter your ZIP code and peruse the database based on the type of pollinator you would like to attract, bloom color, level of sunlight, type of soil, or type of plant. When adding new plants to your garden, check the guide before you buy.

Oh, Ranger! ParkFinder 
Connect with nature no matter where you are. With this app, you can instantly search a database of more than 50,000 federal, state, and local parks and other public lands. Learn more about a particular park, search for parks nearby, or search for parks based on city and state or by ZIP code. You can also search based on 30 activities, including camping, hiking, fishing, water sports, picnicking and more.

Audubon Birds 
Even novice birders will enjoy the Audubon Birds app, which makes it fun and easy to learn about our feathered friends. Search the database or browse by shape, family, name, and more.
