Heh, Google is catching up. I want to highly recommend https://www.komoot.de/plan for hike or bike planning. It's fundamentally based on OSM and very very nice.
Share the recommendation for komoot, although it's quite new, and a bit buggy.
OSMAnd is also useful, not so polished, but you get a lot of power over the way you use the map, for instance searching for attractions, pubs, cycle parking, etc along the way, and it's completely offline.
It's interesting to see that problem from the other direction. That site is useless for me because it can't easily decode US addresses.
Thanks for sharing
It looks nice, but still needs some polish before it's usable for me.
