Customer Reviews


Not long ago I did a section of the PCT using this app. I had no previous experience with navigation, not even at the Park;) but it was easy to learn and use. Not to exaggerate but It worked better than the $800 Garmin my friends were using
Ice and snow made it extremely difficult to navigate; many trails were lost while the melting ice created new miss leading trails erasing the marked trails.
I had no problem getting in and out of the woods even at locations were no phone service was available. (download map areas first to get accurate readings where no service areas)
We encountered one lost hiker that my team and I end up helping by guiding him and teaching him how to use this app.
He got out alive;)
All I can say is that it really works
Don’t break your head

Broke Imports in IOS 11

This app no longer imports of gpx files from other apps via email or airdrop, making the app pretty lame.

Probably adding bugs to drive users into subscriptions...
