The idea behind EveryTrail is simple - use your iPhone, with its built-in GPS and camera, to map ("geotag") photos as you travel locally or around the world. EveryTrail then takes this "geotagged user generated travel content" and creates a unique mashup you can share online with your friend or the EveryTrail community. Start your trip, take and automatically geotag photos and access key travel stats (such as maps, distance traveled, speed and altitude) as you travel.
While reviewing the application, I decided to take a short trip to a local park with my two boys and upload my trip to EveryTrail. I found the application simple, intuitive, and easy-to-use. EveryTrail definitely gets the job done. The iPhone platform is created a growing number of new and exciting applications that really didn't exist beforehand - EveryTrail probably belongs in this category.
Battery life is definitely a consideration and EveryTrail recommends that you set the screen brightness to the lowest level and even turn off WiFi and 3G! This is because the application needs to be active and cannot "sleep" during the trip (In fairness, this is more a limitation of the iPhone 2.0 itself).
If you are an avid traveler or simply like the outdoors, you'll enjoy using EveryTrail to create and share your travel experiences quickly and easily. You can also visit the EveryTrail website to explore thousands of shared trips from all over the globe!
