Help with AreaWalk.

Search for the place or tap Locate, choose Area, then tap each corner on the map. Drag a corner to adjust it, or drag a side tag to pull out a new corner. The area and perimeter update as you go.

Choose Distance and zoom in. Use the crosshair button to place a point exactly at the centre of the screen. Pro adds a magnifier loupe under your finger while you drag. Deep zoom magnifies the imagery; it cannot add detail the imagery doesn’t have.

Walk mode (Pro) traces your path with GPS as you walk the boundary. The accuracy is shown live; wait for a good fix before starting and pause when you stop. Walk mode keeps using location while it is running, shown by the system location indicator, and stops when you finish.

Areas and lengths are calculated geodesically on the WGS84 ellipsoid, so the maths is exact for the points you set. The result depends on where those points are: map imagery can be offset by a few metres and phone GPS typically varies by 3–10 m. AreaWalk is not a legal survey.
