Note: This app complies with Google's scoped storage policy, which means that it does not access any data outside the app, except when explicitly importing or exporting files. If you have the legacy Memory-Map app, you have to install a separate copy of your maps in this app.

The Memory-Map for All app turns your phone or tablet into a full-featured Outdoor GPS or Marine Chart Plotter, and allows you to navigate with USGS Topo maps, NOAA Marine charts, and many other specialist maps, without needing a mobile internet signal.

Maps are downloaded on-the-fly and can be pre-loaded, so they are ready to be used offline. Once the app and maps are loaded to the phone or tablet, cellular network coverage or internet connection is not required for real time GPS navigation.

The Memory-Map for All app can be used as a standalone GPS navigator, but it can also be used in conjunction with the Windows PC or Mac app (free download) for planning, printing and loading up maps, waypoints and routes to the phone/tablet.

Memory-Map for All includes free access to 1:250,000 scale topographic maps and many other free maps around the world. More detailed maps are available for download and purchase with a free try-before-you-buy, time-limited demo option. Available maps include Ordnance Survey, Hema, USGS quads, NOAA, UKHO, and DeLorme. Maps can be used on your PC as well as your phone and tablet. The Cloud Sync feature allows you to keep the overlay data consistent on all your devices.
