I think that my whole problem is described in the title but: I'm using OpenStreetMap based navigation on my phone (OsmAnd) and each time I need to plan a route in advance, I'm having the same problem.

Does anybody know any good tool which I can use, having the features from below:

  * collaboration with friends while editing the route
  * easy way of adding / removing waypoints in the route
  * being able to see nearby POIs, ideally filtering those by categories
  * export of GPX files for your GPS)
