Difficult
Difficult to use and navigate. Need something that just has details of the trails or attractions at the park.
Too many ads
There are just too many ads, pops up at almost every click
Response from developer
The free version comes with a ton of features, like offline base maps, current weather data, push notification for park alerts and news, photo galleries. In addition to that you can download all maps and brochures for one park of your choice for free. Subscriptions make the app ad free and let you download all maps and brochures of all parks.
Great app
Shows me what I need to know (where, what to see etc.) for setting up my trip. You don’t realize how many amazing places we can see at our National Parks until you view them on this app.
