Offline Maps is a practical map companion for travel, hiking, cycling, field work, and any day when you want your map tools ready before the signal disappears. Open the app and start working directly on the map. Choose from Apple maps, OSM vector maps, OSM legacy maps, cycling, hiking, nautical, aeronautical, and other supported sources. Save map areas for offline use where downloads are supported, then keep exploring with your tracks, waypoints, measurements, and coordinate tools in one clean workspace. Record GPS tracks, pause and resume when needed, and keep an eye on your progress with live distance and speed statistics. Saved tracks can be searched, renamed, shown on the map, styled with solid colors or gradients, imported from common GPS formats, and exported when you need to share your route. Mark important places with waypoints, customize icons, rename them, search your waypoint list, and use waypoint tracking to see distance labels and guide lines on the map. Long-press the map or use your current position to create a new waypoint in seconds. Measure what matters in the field: lines, polylines, radius, circles, rectangles, and polygons. Drag points to adjust shapes, save measurements as map items, and export selected data when the job is done. Offline Maps also includes coordinate tools for Decimal, DMS, UTM, MGRS, Plus Code, and GeoHash formats. Copy or share individual coordinate values, open Google Maps links, and quickly search by pasted coordinates or map links. Built for modern iPhone and iPad, Offline Maps keeps the map at the center and places tracks, waypoints, and measurements together in Map Items so your important data stays easy to find.
