Really superb app!

Note!!! This app uses pre-existing maps (trail guides, your local zoos handout, etc), so if your area seems short in maps that you know are out there, get involved and submit requests!
Even up here in eastern Canada there were lots of maps already, and shortly after I sent in requests for about 10 other maps they were added.
The maps are great resolution, and because they are downloaded onto your device they work when youre out of range - necessary when hiking/mountain biking etc! Very uncomplicated layout, and the ability to add points or draw overtop of the maps is bonus. Highly recommended, one of my favourite apps!
