Yes, and Organic Maps and Maps.Me do the same - download entire countries or regions. It is SO tremendously useful when traveling. Have not tried CoMaps yet.

Maps.me, Organic Maps and CoMaps are all the same family.

Maps.me used to be an open source project, when they took it closed source and tried to commercialize it, the last open source version was forked and is now known as Organic Maps.

Then the Organic Maps maintainer started acting sketchy, introduced a paid partnership with Kayak and generally not behaving in a very community minded way. Organic Maps was forked and the new version is now known as CoMaps.

We'll see how long this one lasts.

Yep, that's the beauty of open source: "what do we do if we end up disagreeing with the maintainers?" -> just fork away :-).

What's the secret sauce for transferring one's own annotations and notes among all these apps ?

One imagines there're subtle differences and it's not something worth getting lost in the details of..

I'd see if an LLM can help you get the data, build you a migration tool, and help you migrate it.
