Heard about this app a couple weeks ago and have been using it since. I found this very useful (especially since i'm relatively new to the city) and it doesn't need GPS or data/wifi to bring up the map. Had it loaded onto an ipod touch and it's great for mapping a route while staying on the bike paths. Thought i'd share in case anyone else had been looking for a good map of bike trails in Calgary.
