I'm using Locus maps on my mobile and I'm very satisfied with it. Plotaroute on PC complements already now well with Locus maps on the smartphone. It would be even better if the "anchor points" of plotaroute would be exported in the GPX file so that Locus would be able to detect them as "shaping points". Don't know, if that is possible.
Sorry, anchor points are an internal editing feature for the route planner, so can't be exported with your route.
