Looks like they use both Open Addresses and NAD, a government-provided address database. Both appear free to download, but I don't know how easily it could be actually integrated into an app as I'm assuming that would require some time of API or something. I am also not a developer, just trying to figure out the best solution for navigation without giving all my data to Google. I did notice there's a "Custom Map Server" option in CoMaps settings, so maybe I could manually add something there? Not sure how that works though and maybe that overrides the default database instead of adding to it.

Yes this is what I was looking for, thanks!

Now is there any way to add this data to comaps? Specifically address data?

Do they publish a list anywhere? I'd love to see what they're using and see if I can get it into CoMaps somehow

I haven't noticed search being all that bad, there's just straight up missing data.

Also wouldn't the search function be fixed at an app level, not across all OSM?

Well the only solution I can see is for us to start manually adding everything we can find to OSM unless there's some way to import better data into OSM or CoMaps.

No, looks like they're not, except one I added in CoMaps, so that explains it.

How does Magic Earth have all those addresses then? There was even a restaurant I was looking for the other day that I found on Magic Earth but not CoMaps. Is Magic Earth's map data open-source or can that somehow be loaded into CoMaps?
