Can I print the map, when I try it just gives me a blank circle
By Chris on 29th October 2018

Hi, not sure what you mean? It does allow you to plot 1,2,3 ... postcodes and keep them all visible. Do you mean something else?

ability to overlay plots from additional post codes would be very useful

Hugh, please have a look at How Far Can I Travel.
By Free Map Tools on 23rd May 2018

is it possible to add distances via roads not as the crow flys. example if trying to plot a map showing driving distances NOT distance as the crow flies? trying to plot a map which has driver distances for costs and radios doesn't do that accurately enough.
