If you are a new user, we recommend our new app "Memory-Map for All" instead of this one.

Turn your iPhone or iPad into an outdoor GPS or marine chart plotter, with the detailed Topo maps or NOAA marine charts needed for your activity. Maps are stored on the device for offline use, when you don't have any network connection. The GPS will show your location even where you have no mobile phone signal.

The app can be used standalone, but the maps and overlay data may also be used on your home PC or Mac for planning, and for printing maps on paper. Then upload everything to your phone or tablet and enjoy navigating outdoors with high quality maps.

When you get home you can transfer your tracklog and points of interest back onto your computer, to see where you actually went, analyze your speed and elevation profile, and so on.

Whether you are fishing, paddling, backpacking, mountain biking or sailing, enjoy your time in the wilderness with Memory-Map. We have been developing mobile navigation apps since year 2000, and our products are trusted by mountain rescue teams, police and coast guard stations around the world.

Nav & Log

I've been using Memory Map for a few years now, and have found it easy to use, very handy for navigation, and also ideal for logging trips. I usually take friends along when I'm on the water, and keep the logging function active so that at the end of the day, I can do a screen grab of the trip and email them a record of it - which they always appreciate and enjoy sharing with others!

Good pocket navigator

I use MM for sailing, in conjunction with other navigation tools. Never trust your boat & crew's safety to one method of determining your fix, but having said that, MM is a good nav program to have in your pocket.

Good app, just needs a few more features

I use this app quite a bit for boating & hiking, found it to be the best for noaa & USGS topo maps when out of 3G area. You can pre-download entire areas of maps fairly easily which is necessary when in the back country or on the ocean. When you use the mobile version in conjunction with their PC software it's very nice keeping track of waypoints, routes and tracks. Import/export works well. Marine NOAA maps are free to download, but you have to pay to get many other maps (USGS topo, Delorme, etc). But for ~$20 or so per map region I don't think it's that unreasonable though.

I've compared many other topo apps, all of which seem to be lacking one feature or another. Memory map is worth the $$, but also lacks needed features. I end up having to use use it in conjunction with other apps, which is do-able but inconvenient. Would be much better if they could add a couple additional features, namely: 1) need ability to take photos within the app & tag them to waypoints/tracks... 2) Add 3D view (which is available in the PC version), or at minimum an option to view shaded relief via elevation data. Viewing topos in 3D/shaded relief really helps a ton, and seems it'd be fairly easy to add since they already have all the elevation data.

Overall good app, just needs more features
