What's your go-to OSS navigation app? I've been trying the three in the title. CoMaps is a fork of Organic but Osm seems to be its own thing. Honestly haven't seen a reason yet to prefer one over another besides Osm's pretty bad name.

For public transit (trains buses etc) I use Transit, it's not OSS but the company aligns strongly with me and I like that their employees get four-day workweeks: https://transitapp.com/vision However if there's a OSS alternative I'm not aware of I'm always willing to try it.

For finding businesses I would not expect much.. there seems to be no good answer that isn't Yelp or Google Maps, and of course that kinda goes by the nature of crowd sourced reviews and information. I have GMaps WV but it's kind clunky and I just ended up falling back to Maps unfortunately.

EDIT: Forgot to mention biking. I live in a not-so-bike friendly suburb and have actually found that Google gives me WORSE bike routes than OsmAnd, for what it's worth. The OSM route tends to be more roundabout but safer. My guess is you get more urbanist minded people contributing to these, so that's nice to see.
