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.

Ratings and reviews

The problem I am having is large random location errors when stationary for a while, and in particular if I go into a building (say a cafe). The location just bounces around like crazy. As well as looking silly, it adds spurious distance: on a recent walk it added 3 miles! This makes the track useless for sharing or reusing. Friends' using other apps don't seem to suffer the same problem. I could pause recording, but that's a real hassle. Maybe allowing thresholds on distance moved would help?

Fantastic app for marine navigation, and great value at £25 for the entire UK charts for a year! I love the level of customisation allowable, so much more than other apps out there. It tracks in the background and has proven battery-efficient so far. Really enjoy having official Admiralty charts in my pocket (and tablet, and PC at home). This has become my go-to app for backup navigation at sea!

A year on from my first review, I'm happy to report that it is still as good: It's good for plotting my walks and runs in advance, but also whilst I'm on the move. For use in the mountains it is a handy navigational aid for use alongside traditional map and compass. Con - It would be good if I could rotate the map manually and automatically in the direction of travel.
