This weekend I experimented with a new app for iPhone. The Trails app tracks your hike progress with GPS to record location, distance, elevation, speed, etc. and then allows you to upload the recorded data to EveryTrail.com. The data was surprisingly acurate, however the app must remain open for the service to work. This gives the battery quite a workout. My 3 hour hike used about 40% of the charge.
