Take Your iPhone on the Road: Five Nifty Green Travel Apps

There are iPhone Apps that locate lighthouses, make funny noises and, of course, support sustainable travel. Going green can be easier with an iPhone.

Air Sharing ($2.99)

Air Sharing (by Avatron) allows users to download all kinds of data: web pages, .pdfs, excel docs, etc., for perusal offline. On a flight, in the car, wherever, there's no need to print all those files and carry them in a briefcase. Users can drag and drop files onto the iPhone by simply mounting the device on a laptop. Email attachments can also be sent with air sharing.

Green Travel Choice ($1.99)

This app gives up-to-date information on CO2 emissions for travel via car, train, motorbike or plane. The Green Travel Choice map displays the carbon footprint of the various travel options, and the logbook can be used to keep a personal record. Green Travel Choice was developed by PocketWeb, with the partners Commute Greener! and The International Ecotourism Society (TIES). The App was released in April of this year, and has few user reviews at this point.

Twavel (free)

Twavel's iTunes listing reads: "Warning: Twavel can be addictive and lead to environmentally friendly behavior." Like Green Travel Choice, Twavel allows users to track the CO2 emissions associated with their travel choices, and to compare their carbon footprints with those of friends. Other features include message sending and travel-tip sharing.  The app basically combines twitter updates with a carbon emissions calculator. Twavel features some cartoon-bugs and is a very kid-friendly app.

hike GPS ($2.99)

The American Hiking Society, an organization that protects and supports North American trails, put out this hiking app by Accuterra by Intermap. In 2009, Accuterra's hiking app won Apple's Design Award for "Best iPhone OS 3.0 Beta Application." Hike GPS has 300 recreational map bundles and covers more than 220,000 miles of trails. The app shows realtime elevation and travel stats, so hikers can take photos and upload them to a map. The map image can be sent as an email with a link for viewing tracks and photos on Google Maps or Google Earth, or it can be published on Facebook. A rather new green travel app (May 2010), Hike GPS has few user reviews, but it's a nice way to support American trails.

Super Twiddler ($2.99)

Super twiddler (made by thumbble) might not be everyone's idea of a green travel app, but it's paper-free, and it pushes the guidebooks off the map. Yes, there's also Kayak, Urban Spoon, Where and all those other essential apps, but Twiddler gives travel advice based on your mood. The original app, twiddlerSF, covers San Francisco, and the new Super twiddler covers 27 US cities. You input your mood (energetic, dorky, thirsty), how much time you have, and your location, and out comes a series of suggestions. It has up-to-date information, and integrates Google Maps (for directions) and Yelp (for user reviews). It's a shame that, like hike GPS, it can only be used in the states.

If you have thoughts about any of these apps, or any other green travel apps to you'd like to mention, please let us know.
