If you’re a mountaineering iPhone owner, then we’ve got the perfect app for you: PeakFinder , the popular peak-finding application, has recently gained a USA West version of the app – meaning hikers living in this area can now use the app to discover the names of the mountains around them. Previously, PeekFinder was only available in an Alps version . However, this new addition to the range opens up the application to a much wider audience. Essentially, the app shows full panoramic views of its users’ surroundings, labelling each and every peak within the vicinity.
