When you first run the application, it prompts you to enable the device's Location service. This is used to identify the best available free basemap for your location. You must enable the location service and provide a connection to the internet to allow the application to download the basemap. It is faster if you are on a WiFi network to download map data, but any internet connection will work.
When the map is displayed, you can scroll and zoom. Data is automatically downloaded as you move about the map. Remember this is just a free basemap, more detailed maps are available for many areas.
The maps in Memory-Map are raster images, which means the level of detail in each map is fixed. If you want to see more detail, you have to switch to a different map.
