Buy European

I do use Komoot quite regularly and purchased the offline world map for a one-time fee years ago. Unfortunately, after that, they started a subscription model ('premium') and now many features are locked behind a paywall. E.g., you don't have access to the hiking maps layer that highlights bigger paths (long distance trails, GRs etc.) with a special colors. You can still plan with the Komoot standard map, but without the coloring of the official paths, you may unnecessecerily pick very unofficial paths that aren't well-maintained anymore, which are overgrown with thorns or which simply ceased to exist.

The tool is handy but as the hiking maps are all based on free OSM data and they restricted access after I paid, I always find their business practices a bit shady.
