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.
Looks nice.
Unfortunately for my location and usecase it is not that useful. Map overlays are main issue -there is just not enough info . G-maps are shit, and basic OSM cyclo map is still limited compared to my picks (some mobile OSM clients solve it by showing more layers).
Maybe for checking my planed route but not for planning. But for US or other locations this may be useful tool.
