Crashes when opening Reviews

It is a nice little app, especially for the price. It will find trails, provide maps and directions, and users have posted photos. However, the trail descriptions are minimal, so it would be nice to read reviews. But when I try to open the Review section, it crashes and shuts down. Oh, you *can* get out of the photos by tapping the photo and selecting the Back button. Works every time.

Great for finding good trails

I found this app exceptionally useful while hiking in the Rockies and in my home state. I like the ability to GPS track your progress and upload your own trails but for some reason the GPS actual route gets lost when I upload.

Great functionality but out of date and buggy

This app has great functionality and as long as you're careful it'll work fine. But try editing trail info on modern phones and ios versions and you'll end up stuck and needing to restart the app. It seems like this is a dead product, so it'll only get buggier over time. Which is a shame.
