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.
