One of the best map apps I saw is Mapy.com -- same OSM database, but works way smoother and looks better than OsmAnd. Less features, of course, but 99% of time I just need to see the map.
They have a really nice feature I haven’t seen elsewhere to find a circular walking/cycling/ski route of a certain length. Useful to get ideas on where to go if you have some time for a walk or ride in an area you’re not entirely familiar with.
It's better known as mapy.cz Indeed, works really well, I use it mostly when hiking or cycling, but it's also helpful when sightseeing. It provides all details from OSM tiles when needed.
Do note that mapy.cz is not open source and that they started moving more and more features into their subscription based paid offering... The beginning of enshittification.
