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.
I’ve been impressed with how well cyclers.app works in my part of the US. It does a great job routing me to avoid car traffic even in suburban Texas.
