Has anyone used the gypsy guide for iPad app? It certainly is cheaper than renting the gps guide. I have downloaded the free app YYC to banff and I see that there are now two additional apps - one for Banff, Lake Louise, Yoho and another for the Icefields Parkway to Jasper. These apps are only $4.99 a piece. Are they essentially the same as the gps guide?
