By default, once you start a walk you will be taken to the Map View (which displays all the houses from your walk on a map). In some cases, you may prefer to work not from a map, but from a simple list of households.
The list view can be useful if you are doing bulk data entry or the physical area you are canvassing is not well mapped by Apple or Google.
To switch to the List View upon starting your walk, simply tap "List" at the top of the screen:
If you are on Android, there will be a dropdown instead. Click on "Map" to reveal the menu and then select "List".
