NEVER GET LOST AGAIN
Combine GPS with downloaded topo maps and you can view you current location on a topo map even when you are at that perfect hidden mountain lake that is days from the nearest the cell tower. Use the GPS and compass on your iPhone to see your current location and to align the map with the direction you are looking.
(GPS and compass work without an internet connection.)
APPLE WATCH SUPPORT
View your offline maps and current location just by glancing down at your wrist. You no longer need to pull your iPhone out of your bag to check your position.
DOWNLOAD MAPS
Easily download USGS, MapBox, NRCAN/GEOBC, Thunderforest, and Satellite maps so you can use the maps offline while deep in the backcountry.
PLAN YOUR NEXT ADVENTURE
Be prepared for that awesome journey through majestic mountains, down flower ladened valleys, and over craggy passes. Trace routes to find approximate distances and elevation profiles between locations. After tracing a route on a topo map you can view that route on the Satellite map.
