I'm not sure if it qualifies as "good", but OsmAnd will do this.  When
navigating a GPX track, it doesn't map the GPX track to the underlying
roads.  Instead it just tells you when and how sharp the track turns.
When using its own routing instead of a GPX track it does a better job
of describing the roads to turn on to.  Its not exactly what you've
asked for, but OsmAnd is probably a useful starting point.
