Memory-Map | GPS Navigation with offline topo maps and marine charts
iOS Universal Navigation
Turn your iPhone or iPad into an outdoor or marine GPS. 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.
Although the app can be used standalone, the maps and overlay data may also be used on your home computer for planning, and for printing maps on paper. Then upload everything to your phone 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.
