GPS Hiker is a great and free application for outdoor activities. It supports GPS track logging, GPX file import/export and offline maps (Open Street Map, Open Cycle Map, MapQuest, Hike Bike and Custom Map Image) download and viewing. It also integrates with EveryTrail.com for you to search, view, download and upload trips. Camera, twitter and email features are integrated as well.

While in the outdoors and without cellular service, you can display currently logging tracks and previously logged tracks made by other parties simultaneously on the offline map to make sure you are on the right track. Photos taken during the logging session can be displayed on the map and saved for later use. You can also follow the previously logged track to assist your navigation and check the mileage and altitude information for reference.

GPS Hiker also allows you to search millions of trips from www.everytail.com, read trip stories, view trip pictures and download the GPX files of interested trips directly into the application for later reference. If you have EveryTrail.com account, you can also upload trips with photos to the site and view your own trips directly from the application. Even without an account, GPS Hiker itself is a great trip finder / viewer for your travel information reference.

GPS Hiker is proudly field-tested at Mission Peak, Fremont, CA, USA.
