Customer Reviews


This app is amazing. I've loved Tom Harrison maps for years because of how well labeled and accurate they are, and I'm happy to see how well that translates to the app. The terrain profiles are super useful and easy to use and the search feature is awesome! The day I found this app I spent hours plotting my next hike and putting markers where I've been. The app can get a little slow/ stuck if you have a lot of routes or points of interest up at once, but it's not really a big deal. I wish there was a way to sign into a database or something - I'm nervous now I'll lose all my data! Overall wonderful super useful app.

Perfect hiking companion

This app is great for Yosemite hiking, it even can find your location on the maps. The distance measurement for every trail really helps too!

Yosemite conquered

Great app. Everything you need but I still keep his paper map as a backup.
