Do not rely on this! – Grand Canyon by Chimani Review
Sadly, the app didn't work as stated. Wifi/mobile coverage at the Grand Canyon is sporadic at best. The app promised the ability to use the maps without connection but I could never get it to work. After several attempts, I just gave up. Don't rely on this or you will be very disappointed (or worse). Get a paper park map.
