The area that is defined by the 3words can have a river down the middle of it. Eg the app can give the same 3words on both sides of the river unless the river is very wide.
A what3words address defines an area of three meters by three meters.
Not when the GPS in a persons phone is +-10m, and often much worce.
Lol. Perhaps give a 3 word address that is 10m away from the river...it will still be more precise than a postcode (in this highly spurious example).
