Which are you using?
For most things (day trips, few km after work…) I use multiple of them.
- online and offline mobile app
- trip planner works pretty well
- you can check out places (photos, reviews…) when online
- well maped whole Europe
- not enough information about roads (asphalt, paved, gravel…)
- basically interactive version of KČT maps
- can’t find app
- basic planner, but better for drawing your route
- much more helpful info about roads
- 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.
Sherpa has been a helpful tool.
