Most useful app in my phone

This app is not just super useful, but also potentially a life saver. I lost access to the Internet while camping and hiking in the Acadia National Park, but I was still able to navigate the park thanks to this app: the app preloads the maps so they are available even without access to the Internet, and the GPS in your phone also works independently from the data service, so you’ll see your current location and orientation in the map even without Internet (think about that!).

On top of that, the app will allow you to plan to your stay in the most efficient way. Without it, I would have not been able to make the best of my 4-day stay in Acadia (and Yosemite, a few years back).

One of BEST apps I’ve used

I have 50+ apps on my iPhone and this is one of the top ones. I wish more apps did this — all content is available offline and combined with GPS location services, you can easily navigate your progress on one of our NP trails while you hike. That’s really important because usually you can’t get cellular data service while hiking in the wilderness.

We’ve been using it in Yellowstone and Grand Teton parks and it’s been more helpful than the NPS hard copy maps! Thanks REI, GREAT work!

Free offline maps

I really appreciate that REI put this out and offers offline maps with gps tracking throughout the national parks for free. I almost bought all trails for $30 because I was worried about a snow covered trail in Yosemite but REI tracked me perfectly, recognized every step, never lagged, and even tracked when I turned left and right in real time. I was able to follow where the trail should be underneath the snow using this app.
