Round trips from each trailhead are created automatically. - Sort by course constant, course time, distance or elevation gain. Use "Change Descent" to end at a different trailhead. - "Plan with this course" fixes the route and saves an offline map around the summit in one step. - No suitable course? "Create course on map" lets you tap trails to build your own. GPX import is supported. [Course time planning] - Set time and breaks for each checkpoint, and get estimated passing times from your departure time. - Record actual times and compare them with your plan. Course times are recalculated even without a signal. [Safety while hiking] - Route deviation alerts by voice and vibration, even in silent mode or on the Lock Screen. - When you leave your route, "Add This Trail to Route" adds the trail you are on. - Sunset alerts based on your estimated finish time, excluding time spent resting. - Lock Screen and Dynamic Island: see distance and time, and record summit and descent without unlocking. ■ MORE FEATURES - Offline topo maps: official Geospatial Information Authority of Japan (GSI) maps, downloadable by mountain name. - Trailheads, parking and bus stops: 1,500+ trailheads on the map; start or end your route at any of them. - Photo Scan: detect past hikes from photo location and date.
