the biggest problem I have with switching is that Google Maps is a business directory. open street maps is empty where i live. it works okay for navigation, but not so much for finding a coffee.
Street Complete is a great app for quests regarding existing features, but also consider the feature might not exist at all yet in OSM.
Map Complete is great for adding new features. It also asks a bunch of optional simple questions about the feature which gets converted into the relevant OSM tags. It's browser based but you can just add a shortcut to your home screen to have it quickly accessible.
As many have already told you, you can contribute to OSM, I have put in it almost all the establishments in my area (Not at Big area but...). Although soon I have to update them
im on board with the idea in general, but im not going to do this. it would be an endless effort to the benefit of almost nobody. places go up and down so fast here that google maps is often out of date too. it's filled with stale information and im flagging missing places constantly. every digital community in this country is a garbage pile.
the ride share apps here do use open street maps though, and im making corrections to building addresses when i find something isn't right. it's great.
But you can also just flag it if editing is not your cup of tea.
Here's a convenient, non-techy tool to add notes for others to use when editing:

There's a pretty barebones editor in Organic Maps, but you can also check out Street Complete and Every door (more advanced and less user friendly, though insanely efficient)
Yeah, it's interesting to look through the edit history over the years. With StreetComplete I recently fixed ~8 stores that were many years out of date, during an hour walk.
It's fun to find a real hole-in-the-wall that even google maps doesn't have.
Can you give an example? Because I've just looked at Luxembourg, Nepal, and Aruba, and they're all littered with named buildings and landmarks. Pyongyang even has a fair bit filled in.
openstreetmap.org is a mappers website, not a map users website. It works great for mappers, but is horrible for people who want to use the map to find their way around.
I think the openstreetmap ecosystem really needs a better website for map users.
