Has promise, missing many trails

App seems slick but borderline unusable missing so many trails. For example Skunk Canyon isn’t listed at all, Mesa Trail has scattered patches, and the Bear/NCAR road which Xcel sporadically closes isn’t listed. Noticed all that in 2 min of looking around so I imagine a lot more is missing. Hopefully they make it actually “comprehensive” like the press around the app launch claims.

Thanks for the review. If you tap the reload button in the bottom left corner, those trails should now show up.

Not reliable

This app has one job - to show which trails are open and closed in the area. Unfortunately, it does not reliably do that. Right now in the City of Boulder all Marshall Mesa area trails are closed due to mud, but the app shows them as open. This was also the case yesterday when I showed up to the Marshall Mesa trailhead with friends and found the gate closed. Also, in Boulder County the app is showing Hall Ranch open, when those trials are also closed due to mud.

I was originally really excited about this app and recommend it to many people, but I will stop doing that until the app proves to be more accurate. Until then I’ll just continue to reference the agency websites directly.

Avid hiker, disappointed app user

I live here in Boulder and love open spaces. I’m out with my dog just about every day. Unfortunately, this app is severely lacking. An example - clicking a trail brings up a huge (50% of screen) overlay that covers up the actual trail. Some trails are broken into segments and require tapping through one segment at a time.

Any trails is far from a great app but it is also far superior to this one.

Maybe next time the dev team will consider doing live user tests to get feedback and make the app better.

Developer Response ,

Thanks for your feedback and we're sorry you are disappointed. We will work with the partner agencies to see if there is a way we can merge trail segments. And we'll evaluate other ways of showing trail info. Thanks for the suggestions.
