The comparison framework
Navigation apps are compared on five criteria: offline availability, MGRS/military coordinates, route planning for pedestrians, export features, and suitability for operational use. Each app excels in different areas.
Google Maps
Google Maps is unmatched for urban navigation and road-based traffic. The real-time traffic information and POI database are industry-leading. However: limited offline maps (area download with expiry date), no MGRS, no GPX export, no elevation profile. For field navigation or military use, Google Maps is fundamentally unsuitable.
OsmAnd
OsmAnd (OpenStreetMap Android/iOS) is the open-source champion for offline navigation. Excellent offline maps for the entire world, free. Supports GPX import and export, elevation profile, and raster maps. No MGRS support out of the box (plugin available), steep learning curve, dated interface. Good alternative for budget-conscious users.
AllTrails
AllTrails is the largest community for hiking trails: millions of curated routes with ratings and photos. Excellent for recreational use and discovering new routes. Limited for operational planning: no MGRS, no team edition, no SALUTE reports. The route database is its strongest point, operational functionality its weakest.
MilMap
MilMap is designed for professional and semi-professional navigation where precision, offline operation, and operational features are required. MGRS is the standard coordinate, offline maps without expiry dates, PDF route books, SALUTE reports, team maps, and terrain analysis. Less suited for casual use due to the operational focus.
The right choice
Use Google Maps for city navigation and finding POIs. Use AllTrails for recreational hiking on known trails. Use OsmAnd as a cost-free alternative for field navigation. Use MilMap for any situation where professional navigation, offline use, MGRS, or operational features are required. Many professional users combine MilMap with AllTrails for route discovery.
