Both OSM and Organic Maps are SEVERELY lacking in businesses. So many places aren't in the directory.
You search for fast food and only a couple pop up. Search for s fancy steakhouse by name, nothing. It shows about half of the weed dispensaries in my area...
Is there a way to update the "phonebook"?
Has shitgle been spending money trying to make all other maps unusable? It sure fuckin seems like it.
You can easily add POIs with streetcomplete, osmand or directly on osm.org . Just add POIs whenever you search for it and it is missing. It'll take some time depending on your area but if you don't start today, there won't be an alternative for you tomorrow. Ask a friend to do the same. My area has more pois and details and is more up to date and the location is more accurate than google.
