An increasing number of hikers are using smartphones as navigational devices, eschewing dedicated GPS receivers for simplicity or to save weight. Here are some popular choices for mapping apps, but don't forget that the first rule of hiking is to always carry a paper map — if your phone runs out of power or breaks, you won't be lost in the woods.
1. Gaia GPS (iOS and Android, free and subscription options). Perhaps the most comprehensive set of offline maps and features available.
2. BackCountry Navigator (Android, $11.99). Downloads of free maps, but the paid version offers more comprehensive maps and ease of use. An iOS version is in development.
3. MotionX-GPS (iOS, $1.99 with in-app purchases available). This app has been around a long time. The interface feels a tiny bit dated, but it has plenty of capabilities for two bucks.
4. All Trails (iOS and Android, free, with pro version for $29.99, annual subscription). Clean interface and comprehensive set of features, but maps can only be downloaded for offline use if you're a subscriber.
