I may be the last one to know about the Windy Maps App, but I’m very pleased to have found it. It’s an App specifically designed for hikers. If you examine the Spain maps, you’ll find most of the Caminos. For Spain, there are about 19 downloadable maps by region. The Caminos that I examined are clearly marked. The detail of the downloadable maps is great. Plenty of detail provided for getting through cities. For folks traveling with their iPhones or iPads, this is just another tool to accompany any online or print guides you might have with you. Not sure if there is an Android version or not. Maybe Unklehammy can check that out for us. Buen Camino!
