Having tried several apps for iphone and Android, I collected descriptions of offline ond online apps. Offline Apps Download maps for use without an internet connection OruxMaps Offline Maps (Android): Orux is generally considered the best Android mapping app because it is free and has an incredible raft of features. It will take you some time to familiarize yourself with these features because the user interface isn’t exactly polished, but essentially you can upload all kinds of maps and tiles including GPX, routing, have different user profiles and even track your route (live tracking with an internet connection). Play Store Rating: 4.9/5 Locus Map Pro (Android): Locus is also highly rated by Android users. It has access to huge quantities of different maps (inc. terrain, cycling, hiking, skiing), either while you use data, or as in-app purchases for offline use. You can import custom maps, enjoy turn-by-turn voice navigation or understand places with the incorporated Wikipedia information. Play Store Rating: 4.8/5 RMaps (Android): Similar to Galileo for iOS, you can upload your own maps to this highly-rated free app. There is no navigation or routing, just mapping, but it’s free and has great reviews! Play Store Rating: 4.7/5 Maps.Me Offline Maps (iOS/Android): Our go-to application for offline mapping. Maps.Me isn’t as powerful as other apps, or as beautiful as Google Maps, but the user interface is great and it packs in a lot of searchable travel information on restaurants, hotels, campgrounds, hospitals, police stations etc. The map data is provided by OpenStreetMap (OSM) which is a collaborative open source database with information provided by hundreds and thousands of people. It’s easy to get maps, simply download the countries you need in the app (usually 5-500mb per country) when you have have a good internet connection. App Store Rating: 4.5/5 MotionX GPS HD (iOS): This is one of the top iOS app for a backcountry use. Download the maps within the app and enjoy travelling on backroads and hiking trails with detailled topo maps. Super easy to plan, track and store your exploits. App Store Rating: 4.5/5 City Maps 2Go Offline Maps (iOS/Android): For a couple of dollars, you can download maps for all countries in the world which are stored on your device. The map data is provided by OpenStreetMap which is a collaborative open source database with information provided by hundreds and thousands of people. This app even has inbuilt Wikipedia and WikiTravel information which can be found at landmarks on the maps. App Store Rating: 4.5/5 Pocket Earth Offline Maps (iOS): This highly rated and powerful iOS app allows you to import and export GPX files, download maps (cities, regions, countries) for offline use, route, turn-by-turn navigate and track your trip. It incorporates 500,000 Wikipedia entries which are incredibly useful for travel. App Store Rating: 4.5/5 OsmAnd Offline Maps (Android): As the name suggests, this app has access to OpenStreetMap data which can be downloaded to your phone through the app for offline use. If you don’t want to store maps, you can also use mobile data to access maps. A great feature of this app is the cycling and walking routes. This app includes navigation features such as voice guidance and re-routing. You can also search for addresses and find GPS co-ordinates. Play Store Rating: 4.5/5 Backcountry Navigator Topo GPS (Andoid): This top selling backcountry app has OpenStreetMap and OpenCycleMap information available for download, so it’s not just good off the beaten path. It’s also super easy to import GPX/KML information / GPS co-ordinate information – here’s a great guide to using it. Play Store Rating: 4.5/5 Gaia GPS Topo and Trails (iOS/Android): This backcountry focused app allows you to explore remote places once you’ve downloaded the topo, road or aerial maps. You can import/export your own GPX/KML files by web browser, DropBox and email. The app isn’t as cheap as other options ($20USD) but once you’ve invested, all map downloads are free within the app. Play Store Rating: 4.3/5 NavFree Offline Navigation Maps (iOS/Android): This highly popular, free, OSM app has great features including offline mapping, routing, re-routing, turn-by-turn navigation, Google streetview and more. Play Store Rating: 4/5 CoPilot GPS (iOS/Android): This app is free, and has lots of offline maps available. For iOS users, this is one of the better apps for offline searching and routing. You’ll need to purchase features such as turn-by-turn and voice navigation for a modest amount. App Store Rating: 4/5 Galileo (iOS): One of the most powerful offline mapping apps for iOS, although we’ve found that you’ll need a computer with iTunes to make the most of it. You can upload your own custom maps in a number of formats to the app. App Store Rating: 3.5/5 UDirect Offline Maps (iOS): The UDirect maps are clunky, so we only use them for checking out topography (which happens to be very accurate with this app). You can download entire continents of maps at a time. App Store Rating: 3/5 My favourite at the moment is komoot (online and offline) and Naviki .
