### 1/5 — Wrong

*2023-06-28*

Missing trails, missing restrictions, closed trails shown open, absolutely no vehicle based trails between the 2 counties, why?

### 1/5 — App doesn't work

*2022-09-21, version 1.1.4*

On my iphone with up to date software the app opens and then closes immediately. It needs to be fixed

### 2/5 — Inaccurate & Slow Loafing

*2021-06-15, version 1.1.2*

Painfully slow loading (even over fast WiFi). Inaccurate data: Closed trails show as open. UI uses too small text and hard to read colors throughout. Overall a poorly designed and not maintained app.

### 1/5 — Not reliable

*2021-06-03, version 1.1.2*

I downloaded the app and check it every time I go biking to make sure the trails are open. The problem is that it is never accurate. They never update trail status on the app. I don’t know what else to do to know when Boulder decides to open or close their trails. I have been three times to the Marshall Mesa area where the trails are supposed to be open (green) and when I get there, they are closed. This app is just taking space on my phone.

### 5/5 — looks great!

*2020-04-05, version 1.0.1*

this app has been working awesome!!! thanks and nice job!

**Developer response:** Thanks for the feedback. We hope you enjoy the app!

### 2/5 — Not reliable

*2020-03-09, version 1.0.1*

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.

### 3/5 — A good start

*2020-02-12, version 1.0.1*

I’m sure this app will be changing a lot as it gets off the ground. It would be great if it had cross-country skiing as a filter, as well as ease of use, both for skiing or other uses. Also would be great if you could search for off-leash vs on-leash accessibility for dogs.

### 2/5 — Avid hiker, disappointed app user

*2020-01-21, version 1.0.1*

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.

### 4/5 — Has promise, missing many trails

*2020-01-12, version 1.0*

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.

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

### 4/5 — Looks good so far...

*2020-01-11, version 1.0*

Looks good on a phone, but not on an iPad.  Will this be improved?

**Developer response:** The app is not optimized for iPads, but it still works. We've forwarded your suggestion to our developers for future consideration. Thanks for your feedback!
