What app do u use in long distance walks, like pennine way or coast to coast, cos i think u have internet like 75% of time, so it makes totally different from hiking in mountains. I'm actualy dont trust phones in mountains, cos got disappointed in them few time (low batter, especially in cold weather), so i trust only paper maps. but any regards of gadgets, maps, apps, or just some sort of configuration would be appreciable. Thanks!
