About Memory-Map

The Memory-Map 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 may other specialist maps, even without a wireless internet signal.

Maps are downloaded on-the-fly and can be pre-loaded so that they can 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 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 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, British Admiralty, 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.

Great App. Used it for years. My phone developed a problem in November 2019 which meant my GPS tracking was recording track dates in November 2000 not June 2020 using UTC not BST. Lots of chasing around via ...
