it is just automatically scaled paper map, so you have to know how to read it
Osm clients - I tried multiple of them.
Paper maps - from the same company that makes the Cycloserver maps. You can get set of them for about 100€ (CZ not sure about SK). There is just something special about planning trip on paper maps.
I was researching ridewithgps once again to see if I can justify the premium over Komoot onetime map plan. I finally thinkered around the web view of rwgps and I must admit it is very powerful already in the free functionality. I don’t think I will ever go back to Komoot, but I haven’t decided on the premium package for rwgps just yet.
